Onto The Story

After the portal villain released the creature they called Noumu, I immediately made two clones to get Kasumi and Kirishima-san to safety while I personally get Sumiko-chan to safety. Once we regrouped near the entrance, everyone just grouped together as if they were scared of what was to come.

"Hey everyone!" I said which got them out of their shock or fear. "Stay here until the pros get here, I'm going to fight that thing."

"Wait! Izuku let us help you, or at least me!" Gwen shouted as the villains actually waited for us.

"She's right, Midoriya, you can't do this on your own!" Yaoyorozu-san said to support Gwen.

"I'm sorry," I said softly before turning my back to them while I still faced them. "But I'd rather fight now and let you all become great heroes in my place. After all, I always stayed back in the past and now I won't let anyone get  hurt because of my own fear." 

Before they could hold me back, I quickly made a clone of Miku and Draco to guard them and keep them back. Then, I slowly walked towards the villains while calmly talking. "Kurogiri and Shigaraki, right?"

"Yes and I suppose you'll be the decoy until the heroes come."

"I guess so," I said lazily before making a clone of myself which turned into Kaneki while I took my Kuriyuki form. "But I'm the pro hero Omni!"

As I went to attack Shigaraki, he yelled "Noumu!" All of the sudden the black, bird-like creature appeared out of nowhere and punched both me and my clone through the roof. When we came down, I started to glow pure white while my clone glowed pitch black.

My clone's body seemed to become more muscular with new horns and wings on him. Once the glow subsided showing his black hair with red tips which matched his wings, pants, and arms while he was completely shirtless.

As for me, the original, I felt my body shift to be slightly shorter while wings sprouted from my back. But once the glow subsided, I was revealed to be a white-haired girl in a white dress that had a red skirt while wore small blue gloves that had clear sleeves going up to my elbows.

Once we fell back to the ground, Draco and Miku immediately came up to us and guarded us against the Noumu creature. "Hey, I think it's time for plan B!" Miku shouted as we got up.

No One's POV

After Angelica and Daisuke got up, 5 more clones appeared while each took the remaining quirks before all of the versions of Izuku got into a line. "What's this, plan B already!?" Shigaraki taunted before each clone grabbed their necklace.

"Sorry, but plan B is just starting," Each clone said in unison before shouting: "LIMIT BREAK!"

Each clone glowed their respective color before revealing somewhat similar versions of themselves. Then, Miku and Aurora (Healing) jumped back while Draco, Angelica, and Daisuke walked forward slightly.

As the Noumu rushed forward, Draco grabbed its right arm while Daisuke grabbed his left and Angelica held his head still. "Now!" They all yelled in unison as the others got ready to attack.

Kuriyuki went first with her tails and her hands all made a single white fireball before it became a stream of white fire aimed at the Noumu's brain. "Flaming Neutralization!"

Kaneki used a combined version of his Kagune to strike the obvious weak spot of a brain. "Relentless Strike!"

Spider-Man then swung above the Noumu before using his webs to help hold down the Noumu's legs.

Finally, Deku used another Full Cowl, but this time, his veins glowed, green lightning surrounded his body, and some of his energy arced off of his body. Then he jumped towards the Noumu so fast, onlookers could swear that he teleported there, but then Deku sent a flurry of attacks against the Noumu's entire body. "Universal Calamity!"

Once all of their attacks were completed, the Noumu's head was completely obliterated which stopped any further attack but all of the clones glowed before combining into the original Izuku.

"No!" Shigaraki yelled while holding his hand. "Kurogiri! Get the other Noumu!"

Kurogiri then expanded which let 3 more Noumu get into USJ. Then, the doors of USJ slammed open as Shigaraki's hand was shot.

"Have No Fear, For We Are Here!" Shouted All Might before he tried to punch the buff Noumu (exact same as previous one, I just don't want to say black and be called racist). "What?!" He shouted once the Noumu looked completely unfazed by the attack.

"Sensei! Obliterate the brain!" I yelled to try to help as All Might continued to punch but didn't affect the Noumu.

As I realized that All Might-sensei couldn't obliterate the brain that quickly, he was punched back by the Noumu. Then I looked back towards my fellow classmates and saw their fearful faces.

Before I could think of anything, I self-consciously grabbed my necklace and used Limit Break. But this time, nothing about me changed except that I felt a surge of power. 

Then, I seemed to use One For All and jumped towards the buff Noumu and cupped my hands together as a blue flame engulfed its entire head. Which obliterated the head of the Noumu as I was picked up by a winged Noumu.

"I've had it!" I yelled before I breathed pure fire towards the underside of the Noumu with some amplification using Voice Manipulation. The Noumu released me as I sprouted green wings and flew on top of the Noumu while literally screaming its head off.

Finally, a Noumu with a chainsaw and a big ass sword that could rival the buster blade, tackled me as I fell towards the ground. When I touched the ground, I summoned my Kagune before using it to slam the creature off of me before I webbed the Noumu to the ground before using my Kagune to cut off its head.

Once I defeated the last Noumu, I became exhausted before I dropped to the ground and could only hear the remaining villains go through another portal. After that, Athena-sama appeared with a small smile on her face.

"Good job, Izu." She said while closing my eyelids with her fingers. "Rest easy, my little hero."

That's A Wrap

Powers:
Kitsune Physiology (4 Tails)
Ghoul Physiology (Previously Haemokinetic Constructs)
Voice Manipulation
One For All (Controls 5% Freely)
Spider Physiology
Healing
Dragon Physiology
Cloning

Demon Physiology (Daisuke) - Izuku can use the powers of a Nether Demon, one of the most powerful and eldest demons. But so far, Izuku is only as strong as a Physical Demon.

Angel Physiology (Angelica) - Izuku can use all the powers of an Ethereal Angel, similar to Nether Demons except their powers provide hope and rejoice. But Izuku is only as strong as a Physical Angel, among the weakest of Angels with the least variety of powers.

Super Moves

Flaming Neutralization: (Kitsune) Kuriyuki charges up a flame of immense heat, ranging from red to pure white in color. The blast is stronger as it is charged up and can nearly neutralize anything but takes up a large amount of energy.

Relentless Strike: (Ghoul) Kaneki sends a flurry of strikes towards a target using his fists and kagune. A somewhat normal move that doesn't use too much energy, but is predictable as the blows are made by muscle memory.

Full Cowl: (One For All) Deku uses One For All throughout his body to minimize the danger to his body and maximize the control over the quirk. But so far Deku can only use 5% without breaking apart his body.

Universal Calamity: (One For All) Deku rushes to an opponent before unleashing a flurry of blows using 100% of his power. Each blow must be timed perfectly to maintain Deku's body but also not to let the damage to his body set in.

A/N: Hey! I'm done with USJ, but I forget to include Toga Himiko so I'll introduce her during a filler or keep the main storyline where she meets 1-A during the training camp arc.

Either way, I'm going to be adding a few OC's, but I need them from you guys and I have one definite one. I do want two more to include but I'll have a poll later on for it.
