Alright, my recovery hiatus is over, and we've reached the end of part 1 of the Final War arc. So now, we're going to have a sort of Intermission arc, and it's the third movie, World Heroes Mission! Now, this arc will take place in the MHA in America/World timeline, which means these new OC's will be present in the crisis going on. As for when this arc takes place, we're going WAY back to before the International Sports Festival. This arc takes place between it and the Forest training arc where our heroes first met the Injustice Squad. I don't wanna ramble, so i'll leave things at this, A MAJOR SPOILER WARNING IS IN EFFECT! If you don't wanna be spoiled on events from the new movie, do not read this! But, if you're fine with spoilers, then I hope you enjoy!

While the world rested calmly, knowing they were protected under the watchful eyes of hero society, unbeknownst to all, a new threat was beginning to rise. Deep within the earth in an unknown location, the terrorist organization "Humarise" was taking its steps into darkness. Within their cathedral-like main hall, all its members gathered to witness this historic day. Their leader, Flect Turn, stepped before them all to usher in his new era. 

"At last, the time has come. We of Humarise shall cleanse this world of all who dare freely wield their quirks. We may pray worship to the golden child who was born decades ago, bring the world what we know as Quirks, to this day and era, but that same golden light hid behind it a truly terrifying darkness. And thus, the Quirk Doomsday Theory came to life. Those with quirks will become arrogant, cocky, and narcissistic of their own abilities and will bring ruin to our world. The world has already tried once before to hide such events. Japan, one year ago, a monumental war broke out between those who call themselves heroes and villains. Because of their quirks, they caused untold destruction. And soon, the scale will be tipped once again, but on the entire world in which we stand! It is our duty, as members of Humarise, to rid the world of these quirks once and for all! Those who wield their power will know of our intentions, and they may try to stop us! But we shall give our lives to see our goal to the end! We will return our world to what it once was, a world where the quirkless rule! Now, my brethren, join me as we begin this historic new era!!" Flect spoke to his loyal followers as they cheered with him. 

Flect then raised a small dagger into the air and pressed the end of its grip. A button was on it, and the dagger soon glowed. Then, from within an even deeper part of their hidden base, a massive machine activated, it turning red as it let out an isolated signal. This signal transmitted an activation code to a bomb which began to release a green gas from within a city's sewer system. The gas spread all throughout the city, infecting only those with quirks and forcefully activating them to extreme measures. A man with small wings in his back suddenly had then grow to massive proportions, but at the cost of overwhelming pain which caused him to pass away. Another man with a quirk that let his arms catch fire, he suddenly had his whole body burst into a huge fireball which disintegrated him. Untold destruction and death was happening in this city, with only the quirkless surviving. This was the goal of the terrorist group, Humarise. And this was just the beginning of a threat that would take the whole world hostage. 

However, as Humarise began to enact their plan, somewhere else within their facility, a member was fleeing from the scene, carrying a briefcase in his hands. 

"I have  to hurry.... I have to show this to the heroes.... so they can stop them!" The man said as he carried the only hope heroes would have if they wished to stop this terrible tragedy from occurring again. 

-3 Days Later-

With the world soon learning of this terrorist organization, it came time for the heroes to mobilize. Nearly every pro hero from around the world was on guard in specific locations where Humarise membered were suspected to be. And soon, within the country of Otheon where their leader, Flect Turn, was located, Endeavor and his strike team would soon enact a sting operation to capture him and end this.

And all across the world, in France, New York, Cairo, London, Moscow, and so many more major cities, heroes were beginning their operations to find the bombs that Humarise had hidden. These bombs were determined to carry a gas form of the Trigger drug, a substance that, when exposed to a quirk user, can drastically increase the users output. A normal dose can cause a 10x increase in the quirks strength, but this gas was proven to increase the output by hundreds, maybe even thousands of times. Any quirk user exposed would die within seconds.

But halfway across the world from Otheon, in Tokyo, the final members of Endeavor's strike team were preparing to join the fight. The pro hero, Wrath Queen, would normally join and help as she was part of a secret alliance with Endeavor And Hawks, but due to sustaining critical damage from a villain that's left her in a coma, her position will now be taken over by her son, Cry. He had already taken over her role as teacher for a class of new heroes in Philadelphia, but due to this world emergency, he had to postpone his time of teaching and send his students away for their safety. Jiro was part of his group normally, but she was sent off to New York to assist with locating the Trigger bomb there.

Before he left to join the fight, Cry had one thing to do first. He had to visit his mother. 

"Mom.... It's.... it's me, it's your son. I.... I really wish that you could be here with us, to help us stop Humarise. You're a part of this team, you should be leading the charge.... I'm so sorry for what's happened to you. So I will do everything in my power, as the one who'll stand for you, to uphold your honor and justice. But even if you're still here, i'll be sure to take a part of you with us. That way, your spirit will be with us when we save the world." Cry said as he stood next to where his mother slept. He leaned over and gave her a kiss on her head before someone put a hand down on his right shoulder. 

"Cry, I really am sorry. But it's time for us to go now. Endeavor is about to commence the operation." Wrath Queen's sidekick, Refracta, said as Cry unfortunately agreed with her. He stood back up and turned to join her and the last member who'd be joining them. 

"Is it normal to get really nervous for these sorts of things?" Shinso asked as he and Cry shook hands. With Shinso being a second year now, he could go out on work studies, and his pro he was with, Refracta decided to bring him along as his quirk could prove most useful. 

"Like you wouldn't believe. Just don't second guess or hesitate, and i'm sure you'll do fine. It's good to have you with us, buddy." Cry said as he got a good look at Shinso's new hero costume. It looked like a typical all black S.W.A.T uniform, with the big vest full of pouches to boot, but just without the helmet or the word "S.W.A.T" on it. He also had his binding cloth which was the same as Aizawa's, and his ultimate weapon, his Persona Chords voice changer. 

"Glad to know I can be of assistance. So, what do you say we get this started?" Shinso suggested as Cry and Refracta agreed. 

"Very well. Cry, do you have Endeavor's coordinates?" Refracta asked as Cry gave them a nod. 

"Yes, I do. Let's go." Cry said as he activated his quirk, opening up a portal which they stepped through, coming out the other side and into a moving cargo plane where Endeavor and the rest of the team were.

"Glad you could make it. Alright everyone, listen up! I'm only going to say this once, so make sure you cement it in yourselves! 3 days ago, the terrorist group known as Humarise detonated a gas bomb with devastated a large city here in Europe. 2 days later, we were able to figure out other targeted cities of Humarise. With help from the World Heroes Association(WHA), we also managed to locate the base of operations for Humarise. That is where we are headed now. Take a look." Endeavor explained as every hero looked to a screen within the plane. It viewed a large mansion that sat atop a hill, with thousands of armed guards on standby to oppose the heroes. 

"We have reason to believe that the Trigger Bomb within Otheon is located here, in this mansion. We'll storm the premises and locate the bomb, then deactivate it before its detonation. That is team A's task. Team B, yours will be to find Humarise's leader, Flect Turn, and detain him. If we can pull off both of these missions, then we'll be just a few steps away from stopping this crisis." Clair Voyance, an agent of the WHA, told everyone as they understood. 

"All Might, any words of advice before we get this started?" Endeavor spoke into an earpiece as, halfway across the world in the WHA headquarters, All Might took over to speak. 

"Thank you, Endeavor." All Might said as he cleared his throat before beginning his speech to every hero a part of these operations. From the heroes in New York led by Hawks, to France led by Ryukyu, to even the heroes in Tokyo being led by Present Mic, all awaited the words of the former number one hero. "Heroes, this is one of our darkest hours. This threat is even greater than that which plagued Japan one year ago. However, since then we have grown stronger, wiser, and now, we are ready to face this threat with all our might, and stop it from occurring once again. We will stop Humarise and save our world, that I am certain of. And whether you are a seasoned pro, an earnest sidekick, or even an up-and-comer in training, you all know what you have to do to end this. So go beyond! Plus Ultra! And save our world, heroes!"

With All Might concluding his speech, the loading ramp for the cargo plane opened up. All heroes stepped up to the line and waited for the green light to jump. 

"We're approaching the drop zone. As soon as we jump, we'll be taking fire. Do whatever you must to land on the ground and get inside their base, understand?" Endeavor spoke as everyone gave him nods. Cry used his quirk to change his costume, giving it a darker colour and design than normal, and even turning his normally diamond right arm to black obsidian, making him harder to spot. And moments later, the green light lit up. "Alright, here we go! It's time we put an end to Humarise once and for all!"

With that, the heroes jumped from their plane. They free-falled through some clouds before the city of Otheon came into view, and their target, Humarise's mansion base. And, as Endeavor said before, they immediately went under fire as Humarise's members started unloading rounds at the incoming heroes. 

"Most members of Humarise don't have quirks, so if you encounter them, make sure not to cause serious harm!" Clair said through her earpiece as Cry and Shinso took the lead, falling faster than all the other heroes. 

"Arsenal, take Persona and clear out as many of the ground forces as you can before we land! We want the least amount of casualties as we can get, but be swift about it!" Endeavor ordered as Cry responded with a "Yes, sir!" before using his quirk to cover himself in a dark obsidian armor. Thanks to the extra weight, he fell much faster than everyone else and was protected from the bullets. And Shinso, under his hero name "Persona" dove behind him, drafting so he could keep up and land with him.

"You still with me, Shinso!?" Cry asked through his earpiece. 

"You can't lose me that easily, Cry! I'm right behind ya! Coming up on the ground soon, get ready!" Shinso said as the boys were within 1000ft of the ground.

"Alright, i'd say we're close enough to where I can get a good enough read of the floor! Get ready to fight!" Cry shouted as he used his quirk again to make a portal open up right beneath where the boys were falling. They went through and came out a second which was along the ground, the two coming to a skidding stop between dozens of armed guards. 

"It's the heroes! Kill them!" Someone shouted as a large number of guards shouted "YEAH!" in response. But the moment they did that, they dropped their weapons and gave blank stares. The person who spoke before was Shinso, and thanks to his Persona Chords, he sounded just like the enemy and tricked them into replying to him, allowing him to brainwash a a few dozen members at once.

"Nice one! Now it's my turn!" Cry roared as he used his quirk to make a freezing shockwave emerge from where he stood. As the shockwave spread, the ground would freeze. Shinso jumped up to avoid the attack, while other members of Humarise began to freeze where they stood. Now, only a small handful remained.

"Good work, but you missed a few!" Shinso shouted as he used his binding cloth and wrapped it around 3 enemies at once, pulling them all together and crashing them into one another. 

"It's your first mission, I have to give you some bad guys to take out! Wouldn't be fair for you if I didn't!" Cry replied as he condensed a bolt of lightning in his obsidian right arm and threw it at the remaining forces. He hit the ground between them all and it erupted into a huge explosion which sent them all flying. 

"Endeavor, the ground resistance is all clear! Team B, Arsenal And Persona are now making their way into the mansion to find Flect!" Endeavor's sidekick, Burnin', informed him as Team A was finally nearing the ground. 

-With Team A-

"That kid never fails to impress me, and it seems his companion is talented in his own right. We owe them for making our descent as smooth as possible." Endeavor said as he and the rest of his team landed, half of them staying to subdue the Humarise members outside while the other half stormed the mansion to find the Trigger bomb.

Once inside, Endeavor, Burnin', and Clair scoured through the massive mansion in search of their target. Clair's quirk "Clairvoyance" gave her X-ray vision, allowing her to see through the wall around them.

"Anything yet, Clair!?" Endeavor asked as he blew through a wall of enemies with one shot of his flames.

"Not yet, sir! We'll have to go deeper into the mansion! If anything, i'm sure wherever the bomb is, so is Flect Turn." Clair replied to him as Endeavor changed began to speak into his earpiece again. 

"Team B, what's your status!? Have you located Flect yet!?" Endeavor spoke as it was clear the signal was getting weaker while inside the mansion, all he was getting was static at first.

"We're.... the bottom.... many enemies..... no sign.... Flect.... yet!" Cry said as their transmission cut out. 

"So they haven't found him yet, then. Endeavor, he said they're near the bottom but there's a lot of enemies. Do ya want me to go down there and assist them?" Burnin' questioned but Endeavor shook his head. 

"No, they can handle themselves. I know that for sure. We need to focus on locating the Trigger bomb. We don't know how much time we have until it goes off, and if we can't find it, then this whole city will be lost! Clair, any progress on finding that bomb!?" Endeavor spoke but Clair shook her head once again. 

"No, sir! Still nothing! I'm starting to think it's not here at all, sir!" Clair replied as the three of them stopped for a moment. 

"What!? But that can't be right! The WHA confirmed the bomb would be here!" Burnin' stated as Endeavor went deep into thought. 

"Humarise must've suspected we'd figure out the bomb was here, so they moved it to a new location. The WHA still confirms the bomb is in Otheon though, so at the very least, our search stays within a close distance. Let's just hope Team B manages to find Flect down there and bring him down." Endeavor said as they rounded up the remaining Humarise members they encountered. 

-With Team B-

"Another one to your right!" Shinso shouted as he took out yet another armed guard with his binding cloth. 

"Thanks, I owe you one!" Cry said as the two had descended many levels of the mansion, now deep underground. 

"According to the layouts of the mansion given by the WHA, we're on the lowest floor. Flect has to be here." Shinso stated as the two were coming up on the end of the hallway, a pair a massive doors ahead of them. 

"Then let's crash this party!" Cry roared as he used his quirk to enhance the strength in his right arm. With one blow, he blew down the door and the two rushed into a massive main hall style room. But the strange was, no one was in the room. It was completely empty. No Flect, no transmitting machine, and no bomb. "No, no, no, this can't be right. Flect has to be here, it's the only place we haven't checked."

"Cry, I don't know what to say, but Flect isn't here. I mean, take a look around you. We searched every speck of this place from top to bottom and didn't find him. Even if we missed some rooms, the other heroes surely would've found him by now. Flect was never here to begin with, this was all a ruse." Shinso stated as Cry clenched his fists. The thought that they were so close at the start of all this, and now they were further than ever burned. They needed to find these bombs or else a worldwide mass genocide of everyone who had a quirk would occur. 80% of the population would perish in mere seconds. Failure is not an option, so to have victory slip through their fingers hurt more than anything. And it wasn't just the operation in Otheon that was a failure. New York, London, Tokyo, everywhere the heroes were stationed, they were led to dead ends. The heroes knew the bombs were still in the marked cities, but had no idea where to begin looking for them. "So..... what do we do now?"

-Meanwhile...-

In hopes of not causing a worldwide panic, and believing they had all of Humarise in their grasp, the WHA had not actually released the information about the global crisis. People continued about their normal lives, not realizing what was going on in the world. For the students of Persevering Heights Academy in Philadelphia, their week to train before the International Sports Festival was cut short with their new temporary teacher being called away for urgent business. So now, the students had this week for their own personal vacation time. And some were certainly using it for well earned vacation. 

"Now boarding U.S.Air flight 1107 to France." A woman spoke over a P.A system as, at the International Airport in Philadelphia, Harper Leesons; new student at P.H Academy, was headed off with her family for a trip to Paris, France.

"About time we started boarding, it was taking forever." Harper said as she and her family boarded their plane. Given that flights to France are always packed, their family could not get seats together, so they all sat in separate spots on the plane. Harper sat down in her seat and tried to doze off into sleep, her typical strategy whenever she flies to pass the time. Unfortunately, her attempt at sleep was cut short when the person who'd be sitting next to her arrived. 

"Oh, you have got to be kidding me." A familiar voice said as Harper opened her eyes in shock and saw her mortal nemesis of her class, Lisa Burrows, sitting down in the seat next to her. "It's a 9 and a half hour flight and I have the unfortunate luck of being stuck next to you of all people the entire duration? God, kill me now." 

'Oh fuck me, she's here too!? Why god, why!? Damn it, why didn't I agree to go with Phobos!?' Harper thought as they soon took off, trapping the two together for a flight of pure hell for them both. 

As for the other students, it seemed travel was on all their minds as well. Best friends from Class 2, Amelia and Holly were off to spend a few days in London. Possible new boyfriend and girlfriend, Steve and Stacy planned on visiting Egypt for the week, a hot location for two hot people, in more ways than one. Kira Summers, the ghost girl of Class 2 was headed off to Toronto to visit family for a couple of days. Stella and Jackson from Class 1, unknown the two were on the same flight, were both heading to Rome for a few days. Yes, all the students planned to use their time well, but only one of them was staying behind. Yes, she had much more important matters to take care of. 

"So, that damn hero I fought is still alive, huh? Well, at the very least, we can hope she stays in that coma." Markus Wheeler, leader of the Injustice Squad spoke as he'd just been given information from his groups spy and fake class 1 student, Tika Wilcox.

"She's a tough one to break, so I doubt her coma will last long. But I have bigger news, boss." Tika said as her older sister, Daina, became intrigued now. As for Shield, their 4th and final member, he just had killing on the mind so he wasn't even a thought right now. 

"More news, little sis? Damn, you really are quite the intel gatherer, aren't you? What's going on now?" Daina asked as Tika tossed Markus her phone which displayed secret WHA records. 

"I went into the internet with my quirk and managed to find these files about some new terrorist group. Call themselves 'Humarise.' Apparently, they're planning on blowing up bombs filled with this weird gas that kills people with quirks. I don't know about you, but to me, that certainly does put a wrench in our plans, especially if those bombs go off." Tika said as Markus and Daina agreed with her. 

"Indeed it does. Says here 25 major cities across the world have been marked where a bomb is located. So then, New York's the closest target? It'd be a fools idea to think we'd be safe here, but since these are gas bombs, that classifies them as a WMD, a Weapon of Mass Destruction. If someone doesn't get rid of that bomb over there, the gas could easily spread across the country and infect us all. I for one, would rather not have that happen. But, I also don't wanna leave the fate of the whole fucking world in the hands of some crappy heroes. So, Injustice Squad, how's about we take a trip to the Big Apple, eh? Let's go be heroes for once, how does that sound?" Markus suggested as Daina and Tika both rolled their eyes at him which just made him chuckle to himself. 

"I'm with you for stopping the bomb, but just don't call us no heroes. It sickens me to here that." Daina said as now, even the notorious Injustice Squad was getting in on the global action. Every key player was now set on the board. One wrong move from either side would spell doom for themselves. Only one question remained now as time was ticking. What side would make the first mistake?
