If Deku Had the Omnitrix

Fighting Back

 "Today we're going to an off-campus facility to have rescue training," Aizawa told the class, "So get ready." Iida starts giving orders of how to enter the bus as he was class president. While the students were chatting on the bus, they started talking about their quirks. Kirishima makes a remark about how Bakugou, Todoroki, and Midoria have pro worthy quirks as they're strong and flashy. Bakugou and Todoroki don't say anything but Deku is flattered to have been complimented.

The class arrives at the Unforeseen Simulation Joint - USJ for short - with Rescue Hero 13, and Aizawa. 13 explains, "I'm pretty sure you all know the capabilities of your quirks, but you also should know that some of yours can easily kill. Here, you will learn how you can use your quirks to the fullest potential to rescue people." 

In the middle of the explanation, a black fog appears in the middle of the facility, and a parade of villains start pouring out. "13, protect the students" Aizawa commanded. A villain with hands covering his face and body said, "Where is he? I went through the trouble to bring all these friends who want to see All Might. I can't believe he's not here. Maybe if I kill a couple of kids he'll come out to play."

Aizawa rushes out into the crowd, erasing quirks, and taking them down with his wrap scarf. The students and 13 try to escape, but the fog villain appears in front of them. "There is no escape" the fog echoed "we are the league of villains." Bakugou and Kirishima immediately go to attack the villain, but it had no effect against the smoky body. The villain covers the students in the fog, and warps them into the different zones of the USJ, dropping Deku in the shipwreck zone.

As Deku falls into the water, he turns his watch's dial and transforms. He turns into Ripjaws and surveys the underwater area around him. A villain appears and tries to attack him, but he's able to dodge and fight back. He uses his tail to hit the villain, incapacitating him. His frog-like classmate, Tsu, swims up to Deku and they both emerge from the water entering the ship in the middle of the lake, where he times out.

 Deku, Tsu, and Mineta talk about how the villains found the perfect opportunity to sneak onto school grounds and find the USJ schedule when the press was at the school. "They wouldn't have attacked if they didn't somehow have a way to actually kill him *ribbit*" Tsu commented, which made Mineta start crying.

"We have to work together and protect All Might no matter what it takes. This is up to us, let's be heroes" Deku said determinedly. "ArE yOu CrAzY?!" Mineta whined, "ThE bEsT tHiNg Is To WaIt FoR tHe PrOs To ArRiVe." "The villains here have quirks that are suited for the water," Deku explained. "They must have known what was inside the USJ beforehand, and not what quirks the students have since they put me here" Tsu added. "They don't know what our quirks are, and we can use that to our advantage." 

 "Obviously I can do whatever a frog can do *ribbit* I can jump high, climb walls, and stick my tongue out about 20 meters" Tsu started. "I can transform into about 10 different forms and the time I have to stay in form and out of form is really inconsistent" Deku explained. "I have balls that grow out of my head and they can stick to anything except myself" Mineta added.

Suddenly, one of the villains attacks the boat and causes it to start sinking. Mineta panics and starts throwing his balls at the villains, and Deku notices that they're afraid to touch them. "An enemy certain of their victory is bound to make a mistake. All Might said something along those lines. Now's our chance to act" Deku said confidently. Deku gave them a rundown of what their plan will be while waiting for his watch to turn green again. Once it was time, he turned his watch's dial and chose his fastest alien, XLR8. 

Deku jumps off the boat and starts running on water in circles around the villains, creating a vortex. "Tsu, Mineta, now!" Deku yells, causing Tsu to jump off the boat with Mineta in hand. Feeling inspired by Deku, Mineta throws more balls into the water causing the villains to get trapped while being in the vortex as all the water meets back in the middle throwing all of them up.

Tsu, Mineta, and Deku stay at the shore of the shipwreck zone, watching Aizawa fight and being prepared to help him in case something happens. As XLR8, Deku witnesses time pass slower, making him act instantaneously if something were to happen. This came in handy when the villain with the hands all over his body, started to disintegrate Aizawa's elbow.

 Without thinking, Deku rushed over to help within a millisecond, kicking the villain away from his sensei. Following this, he attacked all the other villains that were left standing, knocking them out, then helped Aizawa stand. "You should've stayed back, you're not experienced enough to fight against these villains," Aizawa said sternly. Deku simply responded, "I couldn't bear seeing that villain hurt you when I could do something to stop it."

The hand villain started laughing. "Wow! Your quirk makes you so fast, it's really cool! Too bad that it won't do anything against my Nomu" the villain said giddily. The giant humanoid bird creature that was standing nearby started running towards Deku and Aizawa, but it wasn't fast enough to stop Deku from dodging while holding his teacher. Deku brings Aizawa. Tsu, and Mineta over to 13 and the other students who just defeated the fog villain, to care for his teacher's arm. Deku then runs back to this "Nomu" and prepares for a fight against it.

Deku runs circles around the giant villain, creating a wind vortex lifting it off the ground. While the villain is in the air, he then starts jabbing it with his sharp claws, but it has no effect. The hand villain started scratching his neck agitatedly, and said: "Nomu, don't hold back against this nuisance!" The Nomu tried, but couldn't do anything against Deku's extreme speed.

The repeated hits didn't do anything against the villain, so Deku had no other option than to just keep the vortex going. "If I just do this until All Might arrives, then -" Deku's thoughts were cut off by the sound of his watch timing out. Deku transformed back to normal, causing the Nomu to land back on the ground, and pick him up by the neck. The other villain walks over to the struggling Deku and brings his hand to his face. Just when it seems like his face would be disintegrated, a loud boom echoed throughout the facility, stopping him in his tracks.
