Put of all of these story ideas, this ones probably the weirdest. I got this idea from the Wolf Deku book in my Scraps and Skills reading list that was based on Teen Wolf. Never seen the show so here's my version.

===

The story takes place near the end of his final elementary year. Izuku's quirk was called Intense Energy. The more excited or intense he gets the more energy he builds up, evident by sparks of energy emanating his body. With this energy, he can enhance his speed and agility, strength, though it only enhances him only slightly. If he doesn't have enough intensity/excitement, he can switch sources to calories, though this means he'd have to eat more than average. The sparks can also change color depending on the type of excitement or intensity he's feeling.

Green = normal

Red = angry or determined

Izuku was born an orphan after his parents died from a crumbling building. He has an odd relationship with Bakugo as a one-sided rivalry/hatred/friend. Bakugo had his eyes on him (not bkdk) ever since he dodged all of his thrown ball in dodge ball, which was an amazing feat by their classmates.

His personality would be calm and mostly be passive of most things. At times he can give snarky or sassy remarks.

Mitsuki actually new Izuku's mother but is unable to adopt him for shitty legal reasons. She thinks that her friends murder was planned by a villain, but the police just thought that she was only grieving. 

One afternoon, Izuku was walking back to the orphanage until he was drawn to an alleyway. He saw a ragged girl growling distractingly. He offered to see if she was okay but was then bitten. The bite actually hurted him and he wore a bandage once he got back. The pain lasted for 4 whole days. No amount of healing quirks or pain killers was able to help. There wasn't any poison or external chemicals in his body so it can't be poison.

Even the police got involved and tried to solve the case but couldn't find the ragged girl. They advised Izuku to keep them in touch of everything around him. One day however, he disappeared. The orphanage lady called the police reporting that his room was shredded and ransacked. They assumed he was kidnapped by a villain and conducted a search, with the Bakugos at times helping them. The only peculiar thing was the signs of clawmarks and that the window was evidently broken from the inside, meaning the kidnapper was already there.

The search went on for 18 days and before they could presume him dead or missing, a witness reported that he's seen him near the edge of a forest looking ragged and looked he was "savagely" scratching himself. The police (and Mitsuki) along with a few heroes wasted no time and went to look for him. They found him just as reported, ragged and scratched though he's seen clutching his head while muttering trying to "contain" something. One of the police tried to approach him but was strangled by him in blinding pain. The heroes held Izuku back and tried to console him but all he said that "it hurts" and to "make it stop". His quirk was cackling wildly and his body began to morph.

Eventually he transformed into a deep grey wolf but incomplete, from the hairless patches on his body. They did everything to try and stop but in the end, Eraserhead, who joined the case, erased his quirk and Izuku promptly fell unconsious. They had ambulance transporting him to the hospital but even with pain killers he kept whispering to "make it stop".

They checked his body for anything different and only saw signs of a second quirk, they simply named "Wild Wolf". Other than that he a case of mild malnutrion and infected wounds but those were patch up. Izuku woke up 12 hours later and the Bakugos quickly rushed to the hospital. During the police's questioning, he said that the pain from the bite was its peak and he tried to sleep it off but then woke up finding an intruder in his room. The intruder said that he was "one of them now" and told him to come with them. When he refused the intruder attacked. He retaliated but thats when the pain began to spike up again and felt his body changing. He threw the intruder out of the window and gave chase.

He spent a long time in the woods unsure of how to go back. At times, the pain would spike up whenever the intruder attacked, only this time with their allies. The detective thanked him and left. But once he exited the hospital, he thought about how Izuku gained another quirk through a bite, who's not AFO.

Izuku spent a week in the hopsital recovering and testing his quirk in the quirk testing room. They discovered he was able to merge Wild Wolf with Intense Energy. The drawback was that his original quirk causes him to be wilder in the wolf form. As for Wild Wolf, his attitude changes to being brash and snarky when used but its doubled during the full moon, specifically in the moon light. They also discovered his werewolf form which took more effort and energy to do so. Thankfully, werewolf bites weren't listed.

Izuku was deemed healthy at the end of the week though he still had a few nightmares about the intruder and their gang. He signed up for therapy and anger management sessions though they were a 50/50 success as their methods would at times insult him and his quirks. The other hard part is Intense Energy requires the user to become excited or intense and with his calm exterior, it would be twice as hard. Thanks to Tsukauchi, the Bakugos were finally able to adopt him who's now Izuku Bakugo.

Skip to the final years if Mid School

Izuku has gained a lot of skills with both of his quirks but he rarely uses his wolf quirk, having a few traumas with it. After staying back to retrieve his notebook (he and Katsuki got into another fight) he got caught by the Sludge Villain and escaped using hia quirks until All Might showed up. He thanks Izuku for his help and bolts off until he realized the bottle was missing.

Izuku shows up where the Sludge Villain's attacking Katsuki and rushed out to help, uncousiously using both his quirks and turned into a grey wolf. He claws at the eyes and the villain lets go then All Might arrives. While everyone was praising him, Izuku bolted out of there, dragging Katsuki with him. Once they were alone, Katsuki huffily said that he didn't need help but thanked him anyway. Once they arrive home, Katsuki checks if Izuku was fine since using the wolf quirk sends him into an episode.

During those 10 months, the two would got to the beach to train for the Entrance Exam. While All Might was searcging for Izuku. Once the day came, Aizawa from the cameras recognized Izuku and Bakugo from the case and were wondering how they were doing (dadzawa!!). All Might was also there and considered his choice before Nezu pressed the button. A zero-pointer appears and Uraraka is trapped until Izuku uses his quirks, this time partially morphing his arm into wolf claws, wrecked he bot. As the exam ends, All Might has made a decision.

That summer, brothers waited anxiously for their letters. Izuku decided to have a walk near the beach and bumpsbinto All Might, however just from his scent he already knew who he was. Startled yet pleased, he explained his whole reason for trying to find him and offered his quirk. While initally amazed by the quirk, he refused explaining that he dislikes heavy responsibilites and that his quirk (he hid the two quirks he has) was already big enough of a burden in his life.

All Might was taken aback by the answer but respected his choice, though he urged him to keep his form and quirk a secret. He understands and the two swap phone numbers to keep in contact. Izuku suddenly recieved a phone call from his mom yelling at him to come home as the letters arrive. He rushed back and through the letters he and Katsuki passed with flying colors. They celebrate and wait for the holidays to be over.

===

The Bakubros (is wat im calling now) are part of 1-A and they meet Uraraka and Iida. Aizawa arrives starts the quirk apprehension test with the usual ruse. Izuku gains solid scores on most of the tests until the ball-throw where Aizawa erases his quirk. He says that he noticed he's been holding back his quirk (he knows about the double quirk) even during the exams and demands him to use his full strength. Reluctantly, Izuku does so, morphing into a werewolf while combining Intense Energy from his anxiety (his clothes morph with his body). Izuku finally gets a score but his body is shaken before he can awe at his results and collapses.

Fortunately, that was the final test and he gains 3rd place, which earns some yelling from Katsuki for a re-match. Izuku first goes to the infirmiry for his damage and goes back to class to introduce himself as Katsuki's brother (adopted). Bakusquad forms, excluding Izuku from the rowdiness, and he decides to sit alone. The next day just before arriving in UA, he bumps into Tokoyami who they hit off for having animal-mutated features.

(Idk much about Tsuyu and Toko's backstory so this is my headcanon)

Tsuyu told of how she did have friends, she's mostly lonely due to her passive expression and frog features, but she does have a friend who has a snake head feature. Tokoyami's life was similar to Tsu's but it mostly revolved around his quirk. A lot of people feared and mocked it saying it was a source of evil, but they were quickly told off. His bird head was fine for the most part. For Izuku, he explained that he didn't really make friends since an incident that involved some scarring, but he assured them he's fine. The two nodded but weren't fully convinced.

That day, they had their first Hero Basic Training with All Might and wore their costumes.

(I can't find a reference for his costume so imagine Kiri's costume crossed with Hound Dog's. He'll have small armor bc clothes can itch in his wolf form. Also this is his mask)

(It's made from a material that can stretch and adjust to his face when morphing, so it could protect his face)

He's teamed up with Koji and are up against Tenya and Ochaco (changing teams here). The former were a strange duo but worked together. Izuku told Izuku about his wolf quirk and they come up with a plan. Koji would call birds with a bird whistle (don't ask) and get them to scout the building. They find Ochaco there and Izuku swiftly captures her in tape. They find where the bomb is hidden and Koji orders the birds to scatter in the room to distract him. This is where Izuku comes in, partially morphing his ears, arms, and legs and fights off Tenya, until Koji grabs the bomb.

The fight stops and Izuku was MVP of it. They watch the others do their battles and Izuku and Koji hit it off being buddies. He soon invited him to his friend group (which at this point is filled with animal-related quirks or features).

Another day another lesson, the class was told about Class Rep and they chose Tenya and Momo (Izuku didn't attract too much attention during the Battle Training). Izuku, accompanied by Ochaco and Tenya, hang out with his group during lunch. They talk about their quirks and goals, and Izuku shakily says that he doesn't like using his wolf quirk as it represents bad memories. They understood this however.

The alarm goes off and the class rush out except for Izuku. He smelled a peculiar scent and went to investigate. Koji tags along, not wanting to mushed in a hallway, and orders a few mice and birds as a lookout. They find where the scent was but find no one there except a few scents still lingered. The birds told him that someone wearing a black hoodie was gathering papers then he disppeared into a purple ring. They went to Aizawa and told them about the intruder.

===

The next day, Aizawa anounced about the trip to the USJ. In the buss the class talked about their quirks and Kirishima pointed out that Izuku had a weird quirk, one that emanates electricity and morphs his body into some kind of animal. Kaminari visibly got excited one he though there was also an electric user but sulked when Izuku denied it. He doesn't explain his quirk but says that it has a few unwanted memories. Shoto perks up a bit and the class understands him.

When they got off, they meet Thirteen (srsly why is she named that?) and the villains come through a portal. Izuku feels his instincts sharpen and wonder who or what's triggering them. Kurogiri introduces himself as usual and sends the students away. Izuku lands on Dunes Area. He scents Momo, Kyoka, and Kaminari's scent and heads over there, until he's tackled to the floor. He looks up and his body shakes as he saw his alleged kidnapper. The girls in ragged clothes, who introduces himself as Maple, greets as it's "bin a long time".

(Just imagine she's wearing ragged brown clothes, her hair being messy, and lots of scars on her face)

Izuku shoves her off and snarls what she's doing here. She says that she's come for him and asks if he's considered their proposal. He snarls never and lunges at her. They fight for a couple of minutes. While Momo's group, after dealing with the villains, heard the comotion and went there. Just as they arrive, Maple was about to deliver a final strike until someone tackled her away. Izuku's saviour was a young adult named, Okanu (derived from Okami, I'm bad with names). 

(Now that I found this, use his clothes as reference to Izuku's hero costume. Also imagine Okanu to be older, like early 20s. Also, Okanu was wearing simple shirts and baggy pants)

Maple screeches what he's doing here and he says that he's been tracking them for a while. He then tells Izuku to go to his friends while he fights off Maple. The two fight intensely and Okanu calmy asks why the pack wanted him as he's "barely older than a pup". Maple screeches (she has a squeeky voice) that the Alpha saw tremendous potential in him and it's none of his business. Okanu manages pin her down before a smoke bomb was thrown and she escapes.

He turns to Izuku and the rest asks if they're okay. Momo replies that they're fine and questions who they were and how and why Maple wanted Izuku. Okanu waved it off and decides to escort them to the plaza. They're wary but agreed, though Izuku's more tense than usual. When they reached the edge of the zone, Okanu pulls Izuku aside for moment and tells him to watch his back as "they've returned" before disappearing again.

The group turns to see the injured Aizawa and the Nomu. Shigaraki was about to kill Tsuyu and Mineta nearby (don't ask how they escaped) until All Might arrived. He dukes it out with the Nomu until he's trapped. Izuku attempts to save him and Katsuki, Kirishima, and Shoto arrive to help and freeze it. Katsuki pins down Kurogiri and All Might wiggles free. Shigaraki commands the nomu to break free and retrieve Kurogiri. In the blink of an eye, the Nomu charges towards Katsuki and All Might wasn't fast enough to stop him. They see Katsuki made it out alive and turned to see ozuku in his place. However they were astonished when he didn't take heavy damage and saw he was in a weird form. Izuku growls that he's done with the abomination (the nomu) and pushes it back with massive force.

The others were shocked at his level of strength but didn't expect to see his appearance. He was using his full werewolf form with red energy sparking from him. Katsuki tells everyone to get back and said that he was more feral in this form combined with Intense Energy. The Nomu charges after All Might again but was intead blocked by Izuku with full force. Powered by his rage, Izuku and the Nomu duke it out and everyone was astounded that he parried with the Nomu. Izuku using his feral fighting skills, managed to savagely rip out the brain (it's more morbid than imagined) and the Nomu dies(?(I mean it's already dead)).

The crowd were only stunned that Izuku had beaten something that was equal to All Might and frightened at his savage behaviour. Just then he collapses, taking the toll of his werewolf form and the intense rage that he used. Shigaraki took the chance to get his revenge but was suddenly shot. The staff arrived and arrested many of the villains but the main 2 escaped.

The class were outside talking about the fight they witnessed and their classmates immense strength. Katsuki was carrying his brother who was shaking with tears as he used the form he hated the most. Tsukauchi approaches the brothers and greets them it was good to see them again. The class perks up as the Bakubros actually knew the detective. He questions them but Izuku left out tje fight with Maple until Kaminari points it out. Tsukauchi pales and question if she was the same one. Izuku nods but added that someone saved them and asks if they could talk about it later. He agrees and saw the questioning glances of the class. As Izuku's carried into the ambulance, Katsuki sighs that it's time they knew. Tsukauchi ushers them into the bus and tells them that they'll exain everything once in the main building. He shares a look with Aizawa knowing that a personal enemy of Izuku returned.

After a few hours in their class, they're approached by the detective, Aizawa, and Nezu. They asks what they want to know and Momo answers about Izuku. He nods and sighs before beginning. He tells them if Izuku's bite case and how he went missing by escaping his attempted captors. They revealed about his second quirk and the class were taken aback that he gained a power from a just a bite (sounds kinky tbh). Kaminari asks if he was a real werewolf but was denied as they tested his power, adding the fact that actual werewolves don't exist (the quirk was also able ro be negated by Eraser). Shoto asks about his quirk and they explained about the Intense Energy and Wild Wolf. Katsuki chimes in that the wolf quirk was a psychological and physical painfull reminder of what happened that day, and how Izuku barely uses it.

Most of he classes heart broke except for Shoto as someone went through a similar yet more tragic experience than him. Before they were released, Nezu says that Izuku's quirk is kept top secret and the info is forbidden from anyone. They understood to keep it a secret and left, except for Katsuki. Izuku wakes up and is informed that the whole class knows and goes home.

===

During the 2 day break, the staff has a meeting with Tsukauchi about the USJ events. They talk about the League, how the Nomu had multiple quirks, and how their goal was to kill All Might. Moving from the topic, Nezu talked about the villain Maple that tried to kidnap Izuku. The staff are briefly explained about the tragedy with Aizawa and Midnight already knowing it. All Might felt a pang of sadness for him that explained his heavy burden, but was also confused on how one recieved a wolf quirk through a bite. Nezu urges them to keep an eye for a moment as they don't know about the second party's true goal.

Tsukauchi added about a saviour who fought off Maple. He has her records from England that shows her crimes: mugging, robbing, murdering, and a few cannibalistic incidents, but Okanu has no records at all. The only record they had of him was being spotted exiting a pawn shop then disappearing in an alleyway. He suggests they keep a lookout for him for questioning his knowledge on the group, which they dubbes "the Pack".

Meanwhile, the Bakugo family were very quiet, noted by passing neighbors as it's rare to hear (or not hear?). The parents got a call from the Principle about the kidnapper's return and were shaky about it. Katsuki and Mitsuki weren't yelling and Izuku has been shunned in his room all day, glancing only at his phone for his friend's text. They said that they knew about his incident and want to check up on him but he replies in short and small texts reassuring that he's fine. He rarely leaves the room and only comes down for news and meals.

One day, he's seen out of his room. Mitsuki asks where he was going and he said to have a walk near the park. The parents tense as they're scared he might get kidnapped again but he says he'll be fine and walks out.

At the park, he began wonder when the nightmare will end and why they want him to join. A rock was suddenly tossed at his feet with a note attached. He pulls the note and saw it was for him.

I know you have alot of questions so I'll try to answer them.

Look on your left (lol reference)

- Signed [taped blue fur]

Izuku doesn't know what to think about it and saw a shady figure with a furry hood. He was momentarily shocked that he had a blue wolf tail. He contemplated on his chances before walking to him.

He monotonely greets him and walks him to a more secluded alley. He reintroduces himself as Okanu and asks what he wants to know. Izuku wants to know about what's been going on, ever since he was kidnapped. Okanu sighed before beginning.

Before the dawn of quirks, yokai animals existed and lived separate from humans. One of thses yokais were the werewolves. The first yokai animals to be born, the prime yokais, had the power to turn others into one of them or revearse, just from a bite. At one point, there was a yokai war and the Alpha werewolf at the time decided to have a child bearing his powers so it could be pass down. The other yokais heard of this and followed suit. But soon the wars became more devastating and made the Kitsune leader to not court with anyone, including the other yokais. However, the Alpha werewolf was corrupted and continued to influence his offspring to bear children. Some refused but there were always relatives.

When the quirks first appeared, the yokai kingdoms easily blended in as quirks to human government eyes. Some beared children with fellow humans and thanks to quirk genetics, their power merged with the quirks and soon became one with them. Okanu himself was one of those born from werewolf and human. The kingdoms soon dispersed, adapting into modern culture except the Alpha. Rumors say that he despised the human race and only gave werewolf powers to those he saw "worthy". He planned to overthrow the humans until the Kitsunes, a former ally of them, banded with other yokais to kill him. They succeeded, but he got away with bearing descendants. Since that day, the yokais swore a pack to find their descendants and stop history from repeating itself.

Izuku was in shock at the hidden history of yokais. He look down on his hands, thinking that Maple bit him because they saw him as "worthy".  Okanu read his mind and said he was unsure on how he gained their attention. Izuku asked about how the yokai quirks worked and were passed down. Since one yokai would need to court with a human to bear quirk offspring, the prime powers would hold the quirk genetics but the powers were hereditary and the same to the absolute. Those who weren't direct descendants had their powers as normal as human quirks.

Izuku wondered how he could get the Alpha to stop his search for him. Okanu looked deeply uneasy. The order of the pack is ordered by the Alpha's word and if one defies him, they would need to challenge him to the thrown. This was the only werewolf tradition that has never been changed. If Izuku wants to get them off his trail, he'll need to face him head on. Okanu grimly adds that the current Alpha is merciless and that a challenge might end by death.

Seeing Izuku's stiffened state, he tries assure him. He'l try to get as many of the packs of his back but one day, he'll have to face him alone, and bids him farewell.

That night, the Bakugo's couldn't tell why their youngest was in a state of shock all day.

===

The students went back to class the next day and saw Izuku looking withdrawn yet better than during the USJ incident. Aizawa enters and talks about the Sports Festival and the big chance to get hero eyes on them. Izuku and his group talk about a group training during lunch. They could improve their fighting styles by using different terrains, and there would be no schools for the next 2 weeks. Izuku has an idea and knows a mountinous place where they could practice, as well as many animals for Koji's quirk.

Before home time, 1A was blocked by a crowd of students and they talk about if one of them proves themselves, they might be able to enter Hero Course, and vice versa. Shinso comes up and declares war on them and Izuku notes that even with his calm exterior, he sensed a fire determination inside, just through scent.

The next week, Izuku's group, including Tenya, Ochaco, and Katsuki, were brought to the Bakubro's personally training area. They have been using the terrain since they were 12 and created and hand-made obstacle course. The group trained vigorously: Katsuki was training his agility and manuverability, Iida training his speed and evasiveness, Ochaco and Tsuyu strengthening her quirk and practicing parkour, Koji using his quirk while doing the obstacle course, Tokoyami sparring with Izuku with and without Dark Shadow, and Izuku doing parkour with his quirks.

===

The day of the fesitval, Shoto declared his war against Izuku in the waiting room. The class were shocked but understood that they were also against each other in the festival. The first event was an obstacle course. The students would have to go through a series of obstacles placed by the teachers, anything goes as long as you're within the course. The Dekusquad plus Katsuki grinned as they have practiced all week.

The event starts and Shoto freezes the contestants with his quirk. They're soon face by robots from the Hero Exams and the dual-colored student passes with ease. Izuku passes through by morphing his claws and grabbing a metal piece for uses. 

They come up against a large gorge with tight ropes and very few were able to make it. Izuku took more time by simply climbing on the ropes.

They reached the final obstacle which the ground was covered by buried but harmless mines. Katsuki and Shoto were at neck and neck trying to gain first place, until they were overthrown by Izuku launching himself with the metal piece from an explosion.

He gains first place but is soon a target of many for recieving 10M points. He makes his group with Tsuyu, Tokoyami, but couldn't find a fourth member. He suddenly scented another determination in Shinso and calls him over. He was awkward around a few Hero Course student but agreed to join them.

They introduced each other and relayed their quirk, Shinso was internally surprised that they shrugged off after hearing about his quirk. Izuku's plan was to use Tsuyu as an extension to grab headbands, Tokoyami multitask of attacking and defending, himself as a lookout with his senses, and Shinso to lure others inti their trap.

As the second event starts, many teams went after Team Bakugo 2(?) headband. Shinso was was able to rile others to use his quirk and grab their points. Near the end of the event, they bumped into Shoto's group. Hey had a hard time avoiding him, with Shoto accidently using his fire, until the time ran out and Team Midoriya was first place.

While everyone was out for lunch, Shoto confronted Izuku about how he broke his vow. He told about his childhood with Endevour and how he loathes. He switched topics to Izuku's backstory seeing how they're similar. But to his shock, Izuku denies their similarities. While they are hesitant of using one side of themselves, he's not afraid of using just a fraction of it, while Shoto rejects it completely. Izuku left as Shoto ponders about their differences and similarities.

Izuku bumps into Okanu on the way to the cafeteria. He greets him and compliments him on his words at Shoto and his skills. Izuku was startled that he eavesdropped but thanked. He asked what he was doing and simply said that he was here to see his skills. Izuku couldn't help but feel warmth by his compliments and began to think of him as another brother.

The final event starts and the first battle of the first round is Izuku vs Shinso. While Shinso was glad to work with Hero Course students that didn't judge him, but he didn't exactly care for them. As the fights starts, he promptly taunts Izuku about his class while dodging Izuku's slashes. In frustration, he tells him that 1A is probably full of freaks like him and the "bird-head", before realizing that he went to far. Unfortunately for him, this enrages Izuku and went full speed at him that it was all Shinso could do dodge it. He sputters saying he didn't mean it before being thrown out of bounds in the face by werewolf kick. He gets up and realizes how messed up it was taunting just by someone's look and tries to apologize, but Izuku already exited the field.

Izuku shuns himself in a waiting room waiting for his anger to fade away and saw Shinso in the room. He snarls and demands what he wants, Shinso meakly says that he wants to apologize, until Izuku threw a bottle he was holding just above his head. Izuku felt betrayed that Shinso mocked someone that they were born with and yelles that he was hypocrite for doing so. Shinso tries to apologize again but stops knowing that he needs some space and walks away. He clutches his hand, angry at himself and knowing that Izuku's last statement was true.

While they were sulking, the rounds continues just normal with Katsuki winning against Monoma and Shoto beating Sero by a landslide. Once all the battles were finished, round 2 begins with Izuku vs Shoto. Both fighters held nothing back as soon it began. Izuku scaled all of Shoto's glaciers with wolf feet and destroying them with his intense energy. As the fight went on, Izuku grew frustrated and began to go on all fours, morphed limbs. He angrily yells Shoto that he's being selfish for half assing his power. Shoto argues but Izuku gives a number of ways civilians could die if he didn't use his flames.

Shoto begins to hesitate on his words but replies that he'll find. Izuku shouts that if he wants to be a hero just to spite Endevour then he's no true hero at all. This sends him in a flashback where Shoto, a day after his mother was sent to the hospital, angrily states that his father is no hero as he just wants to be number one. He snaps out when Izuku pushes him back with a side-kick and hears him yell, "IT'S YOUR QUIRK ISN'T IT?! YOUR QUIRK NOT HIS!!". 

Shoto stops stunned at the revelation. He remembers his mother saying that he's not a prisoner of his blood and All Might's words on a talk show of how children were still their own flesh and blood. He tears up and flames bursts from his left and smiled. He states that Izuku was crazy im helping his enemy, but Izuku was okay with that. Shoto first shoots out his ice only for it to explode with a grey wolf with green markings in its wake. Izuku states (in a deep voice) that since Shoto's going all out, he'll do the same. He sprints towards him while being surrounded by red lightning. Shoto uses his flames and the arena explodes.

As the dust clears up, it's revealed that Izuku won, in his wolf form by pinning his amrs with his muzzle close to Shoto's face. Shoto openly declares that he yields and the match concludes. While being treated by Recovery Girl, Shoto reminiscents about his past and his hatred for his left side. He thinks back to Izuku's statement that he was no hero for only trying to spite his father. He tearfully realized that if he continued his vow he would turn out become like him.

Back in 1A's stands, they were talking about how Izuku turned into a wolf. Katsuki replies saying that's only one of his forms and that the werewolf form will be a real challenge. Izuku sees Okanu giving an approving smile and thumbs up and sits down with his friends.

The festival reaches its final round, with Izuku winning against Iida by flailing him around by the leg, and Katsuki impressively beats Tokoyami. Eventually the final battle is Katsuki vs Izuku, a battle between brothers. Both go full out but Izuku loses when he was pinned by his face and chest. Not risking to be blown, he surrenders.

The festival concludes with Katsuki in 1st place, Izuku in 2nd, and Tokoyami in 3rd.

When the Bakubros went home, they are greeted by a surprise party by their parents and celebrate their victory. Izuku also recieved a surprise text from Okanu congratulating him. He smiles and adds him to his contacts.

===

During the weekends Okanu invites Izuku over for training his wolf quirk. They had fun throughout the day, sometimes acting like actual wolves. During their break, Izuku asks about how he lives in today's society, as he legally doesn't exist. Okanu was actually born in England. His mother was of Japanese descent and named him after his heritage. In truth, they were living as refugees from the Pack and avoiding human contact as possible. However, the pack soon caught up and they burned down the buidling they were hiding in. He was 18 at the time, his mother died in the skirmish and the authorities presumed him dead, but the Pack discovered his escape after a few years. He later immigrated to Japan where he met several humans and werewolves in hiding.

Izuku looks down feeling sorry for Okanu. He wonders if they were the only pack and Okanu says that there are many packs, and the term is just another for family. Okanu has his own pack, which refers to as a guild, that have a mix of human and werewolves. They were living peacefully at most but wished that the Pack would just disappear.

===

Aizawa announced the internships and the class got excited. Since the Sports Festival, a lot of them caught the eyes of pros and shows the tally of offers. Surprisingly, Shoto got the most offers, followed by Izuku, then Katsuki. Izuku comments that it's they probably think he's crazy for helping his oppnonent. Shoto states his is because of his father, and the class notes the obvious reasons behind Bakugo's which earned a a scowl.

The class discussed on which they'll intern with. Shoto saw Endevour Agency on his offers and flashesback to a few minutes after his defeat. Endevour was angry and demanded to know how he lost.

"I am not you".

"What do you-"

"It means I'm done with following you. I realized if I continued persuing my goals because of you, I would stoop just as low. So from now on, I don't care what you have to say. I'm gonna be a hero my own way".

Katsuki picked Mirko on his list as she's known to by wild and sometimes feral like him (stated by his brother). Izuku was conflicted with his choice. He was torn between Edgeshot, a hero known to have a calm mind and elegant yet deadly fighting style, and a small-time yet popular hero, Springleap, who's known to have spring-like structures in his limbs that helps increase his output of energy. His fighting style was a mix of martial arts and feral style while wielding a bo-staff or sledgehammer, but his personality is described as cocky yet clever at the face of a villain. His agency was small with a few sidekicks and has a second agency in a countryside, where he goes to every summer. Ultimately, he decides to go for Spingleap after discussing with Katsuki.

The 2nd day for discussing on their internship, Aizawa anounced that Shinso moved to the Hero Course. He introduces himself and sits in Mineta's former seat. Some note on how Izuku acts disgruntled around Shoto and Shinso, despite how well he got along with the latter. Later in class, Izuku hands a note to Shinso.

"I know what you said was only to taunt me, but it still hurts. I'll try my best to forgive but I don't think I'll forget. Try to watch your words next time, even on the battlefield".

Shinso quietly thanks Izuku for giving him another chance.

Midnight later came in to help them with their hero names. Izuku chose Lycan (I'll need a better name) and when the day arrived, he packed his stuff, but he did sense a burning determination from Tenya, and not the good kind. 

His first greeting at the agency was almost being shot by a bo-staff, embedded into the wall, by a feral grinning pro. Springleap (plz help with the real name. Something that means "leap" or something) was very interested in Izuku's fighting style and showed him some martial arts moves, but at times he would pin him down for seemingly no reason. He got frustrated at this but realized he was pinned down because he got annoyed, so he would need to calm his anger. This soon worked and Springleap congratulated him by giving him a proper spar.

On one of the days, Springleap was called by another agency in Hosu, to request help on finding a small thug gang that's responsible for a few thefts. He invited Izuku along for his keen senses but were attacked by a Nomu in the train. They wasted no time in dealing with the attack, but Izuku soon froze smelling Iida's blood scent as well as a peculiar, yet sinister scent (in a way, he can identify a person's aura by scent). He came in just in time to rescue Iida from Stain. While fighting, he heavily snapped at Tenya for being reckless for revenge before being paralyzed by the Hero Killer. Luckily they were saved Shoto and together, they knocked him unconsious (Izuku got a bit carried away by giving large scratches). When pros started to arrive, Izuku was snatched by a flying Nomu but was then saved by Stain who freed himself. Stain's speech was recorded by a reporter before going unconsious.

The three were berated by the police for their acts of vigilantisms but narrowly escaped punishment after a video feed caught a brief battle moments. They were complimented them as heroes, but were still warned not to do it again.

On the last week of the internships, Springleap taught him a few tips on how to control his temper by making help with the paper work. The idea was to sort out the files quickly and efficiently. Eventually, the internships came to a close and Izuku kept in touch with his mentor.

The three were immediately hounded by questions the moment they returned to class. Katsuki was pissed and worried sick that Izuku bumped into a serial killer. Aizawa mentioned about the Mid-Terms exams and the class were in panic about it being near. The Bakubros had no problem as they studied together. Izuku even invited Shoto, Tenya, and surprisingly Hitoshi to help tutor them, which they accepted. 

Once the Written Exams were done, they went for their Practical Exams, which were beating the teacher. Izuku was paired up by Koda and were up against Hound Dog. The teachers discussed that although his anger had more control than Katsuki's, Izuku was still impatient, so they paired him with a quiet boy like Koji, against someone who's also wild but more calculating. Thei fight started off bad as Izuku immediately rushed in to battle Hound Dog but was countered every time. When he was down, Koji distracted Hound Dog with a bird tornado long enough for him to rescue Izuku. This snapped him out and finally came up with a plan. Eventually they passed the exams.

===

The results came out and turns out that Mina, Sero, Eijiro, and Sato failed the practicals but still succeeded the written exams. Mina invited everyone to hang out in the mall in a few days. Nearly everyone agreed, but Izuku said that he'll think about it as he wants to visit a friend for something. Everyone understood, but his brother couldn't help but be suspicious of his supposed "friend".

Izuku went to visit Okanu and told him about the training camp. Okanu was visibly upset that he'll be gone for a week but wished him luck. They changed topics to Katsuki and Okanu asked why he wouldn't introduce him to each other. Izuku says that his class knew him by name, the one who saved him from a feral villain girl, and he's scared Katsuki would freak out. The one mentioned was, eavesdropping was surprised and he can see why Izuku would keep him a secret. Katsuki left after that, understanding that Izuku needed time to "introduce" him to him. They soon left and Izuku went to wander into an abandoned underpass when her heard a distressed trilling.

He saw a girl with fox ears and 3 scarlet tails was growling at a villain with a blade-nail quirk.

Izuku came to her aid and together they fought of the villain. He saw a few cuts on the girl and went to bandage them. The two had an awkward moment and the girl decided to introduce herself first as Akasuki Himura, who was the same age as Izuku. They hit it off exchanging info until they realized they were both yokai, Suki (for short) being half-yokai. She was a kitsune yokai, inherited from her mother. Her quirk was Scarlet Fox, which allows her to transform into a red, nine-tailed, fox-shaped spirit.

(The design is like the cat ghost in the image)

The two hit it off instantly and shared phone numbers. Izuku arrived at the mall with his class for the shopping trip. He was suddenly put into a gentle neck hold by Shigaraki. The villain interrogated him, while also taunting about his past he somehow discovered. When Shigi realized his conviction, they were confronted by a horrified Ochaco and Izuku was released. 

The situation was reported by the poloce and even a few reporters knew, but left out Izuku's name. Akasuki comforted him when he told her about the villain and gave him a few tips on how to calm down. They enjoyed each other's conversation and Suki was soon introduced to Okanu who shared the same sentiment.

The day of the training camp begun and while everyone was frightened of the forest area, Izuku embraced and enjoyed it, releasing his wolf instincts and let loose on the earth-beasts. They arrived faster than canon, about 2 hours and met Kota. During an accident in the hot springs, Mandalay told him about his hero parents and his resentment towards them. The class were more than haply to get a gopd night sleep, but Izuku insisted on sleeping outside in his wolf form, saying his instincts have never felt more free. Coincidently, he slept in Kota's hideout where the said boy was startled by his appearance but decided to sleep on him. He secretly enjoyed the wolf's warmth.

The beginning of training was hellish for everyone. Shinso, while not having a physical quirk, trained with Aizawa on using his scarf, and other times trained his migraines from his quirk. Izuku's session was torturous. Aizawa setted up a container designed to make an artificial full moon, to activate his quirk's wild stage. His training included playing games involving patience and normal chores, while resisting his urge to run wild. Kaminari commented that his training was easy compared to the others but was countered not unless he wanted to be shocked by a shock collar.

Izuku sleeping routine continued throughout the whole week, with Kota gradually enjoying his presence. Izuku caught him prodding on his fur and instead engaged him on a conversation.

The Pussy Cats began the Test of Courage. Izuku was less than eager to do so afraid that he'll run wild, especially on a full moon night. Before 1B could ready their positions, Izuku alerted of unidentified scents in the area and Pixie Bob was attracted by a Magne's quirk and fell unconsious. Both classes freaked out and the teachers sprung into action. Izuku became afraid of Kota safety and darted towards the mountains. He was faced against Muscular who beated him half to death and fell unconsious. In his consious, he's met by another vpice which turned out to be his wolf self. He expressed on Izuku's fear of the werewolf form, not wanting go wild and possibly harm someone. He says that instead of restraining it he should embrace it, directing his attitude instead of controlling them.

Accepting himself as a werewolf, he transforms into the form and wins against Muscular. Once he was done, he sent a an SOS signal to Okanu and Suki on his other phone and carried Kota on his way. He soom had to let him go and told him to be carefull after smelling a very familiar scent. Kota was soon picked up by Okanu and was told they were friends of Izuku and were vigilantes. He and Suki were helping the teachers fight off the villains and rescuing the students.

Aizawa though skeptical, thaked hem for their help, including the 1A. When thibgs were calming down, now that the villains were retreating, Okanu's radio called with Suki on it, exclamining that the Pack was here and have Izuku. Hearing this, the 1A and Okanu rushed out to help when they were blocked by mutliple werewolves of the Pack. The alpha soon revealed himself, holding Izuku on a choke-hold. The Pack formed a ring around the Alpha and Izuku, and held Kota hostage in case the class and teachers tried anything. The Alpha proceeded to beat him up with Izuku barely holding his own. The Alpha was infuriated that he refused to join and snarled that he was as useless as his father. This shocked the Bakubros meaning that Hisashi and Inko's murder was planned all along.

Hisashi was known to have a strong will and care for others. Despite having a fire breathing quirk, he worked with the police as an investigator where cases were almost always a success thanks to him. The Pack soon caught wind of this and offered him to join. When he refused, he went into hiding and soon married and had Izuku. The attack on them was supposed to try and force him to join but ended up in failure and killed him. The Alpha decided to target Izuku but they lost track of him.

Enraged by the story, Izuku began to retaliate but his efforts were in vain as he was promptly pinned down. Annoyed by his continuous refusal, the Alpha decided to go after Kota as it would hurt him more. This was when Izuku truly snapped, escaped his bindings, and ultimately challenged him to the throne in order to protect his friends. The Alpha was shocked but mocked that Izuku had no pack. Izuku merely stated that his class was his pack, slipping out that they were his family.

Angry, both fighters turn into werewolves and fought. The class and the Pack were cheering for their respective competitor. At times a member of each parties tried to interfere but were stopped. At one point, the Alpha held Izuku at a huge disadvantge but to his shock, Izuku escaped snapping one of his fingers to slip away and next thing he knew, he was bitten down from the head. The Alpha tried wriggle away but as he did, Izuku ripped his right ear clean off and he roared in pain. Both parties stared in shock and anticipation as the Alpha was down and Izuku having a clear shot. Just when he was going to deliver the final strike, Izuku refused saying that the Alpha already lost. 

Maple, and even the Alpha, refused to accept this as it would only show cowardice, but Okanu interjected revealing the Alpha's name, Cyrus, that Izuku showed honor in battle by showing mercy to a downed opponent. The classes cheered for Izuku and the siblings were hold down by the Pack who accepted Izuku as the new Alpha. Okanu and Suki were there to congratulate them.

===

A day only passed after Izuku explained the whole werewolf history to his class. Katsuki eventually accepted them before he could "murder" them, and Okanu relayed tgat the Pack was taken care of by his Guild. The cell tower was taken down during the attack and the bus was destroyed, so Vlad had to use the only car to get help. The place was in a mess but the PussyCats, classes, and teachers were feeling fresh after the Pack challenge last night.

In the morning, Aizawa informed that help would arrive in a few hours and urged Okanu to leave with the Pack (he was greatfull that he allowed them off the hook). There was some difficulty on the Pack's end as they refused to leave without their Alpha, who was Izuku. No one had an idea until one of the werewolves suggested that Izuku's "mate" could lead them instead. Everyone was confused and Izuku was was embarrassed saying that he didn't have a mate. This in turn made the pack confused as they pointed out both he and Suki have each others scent. The class eventually realized of their relationship and Mina, Kaminari, and Sero teased him about it.

Okanu however thought it was a great idea, and he could help Suki by being the Beta (the second in command). Suki was overwhelmed at first but accepted the position, as she had no family to return to. Before they left, the two shared a private moment and prommised to keep in touch. Just as the authorities arrived, they left. Izuku had to endure constant teasing from his classmates about his relationship.

THIS WAS HELLA LONG!!! I cannot belive it took like a motnh for me to finish. Anyway, the League failed to capture either Bakubros and one of the Nomus had a tracker, which lead to the Kamino Raid. Everythings normal.

Like I said this was probably the weirdest idea I cam up with. Leave your thoughts in the comments.

IM OUT!!
