Izuku Midoriya was currently in the locker room with the other boys of Class 1-A as they all changed into their costumes. Unfortunately, his hoodie had been trashed in the Battle Training and they still hadn't repaired it. Suddenly, Izuku disappeared in green light and was now dressed in his hero costume. The other boys gaped at him.

"W-What? How did you do that?" Kirishima asked as Izuku rubbed the back of his head sheepishly.

"Uh.. my support item lets me change what I wear in my forms so I just set a default for when I wasn't transformed," Izuku said as the other boys stared in jealousy.

"Jeez, man! You really have to tell us who made that thing. I'd kill for an instant clothes feature." Sato said, shaking his head in amazement.

Izuku absentmindedly nodded as he adjusted his shoes and made his way to the entrance of the school. Their hero training for today was Rescue training which Izuku was pretty excited about. He could already think of ways his aliens could help in various situations.

'Way Big could help people who are high up on collapsing or burning buildings and carry them in his palm down. Speaking of fire, as Heatblast I could just absorb the flames or freeze them over with Articguana. Ripjaws could help in aquatic rescue, although he might scare the people I'm helping. Upchuck could just eat any rubble in rescue scenarios. As Lodestar I could-' Izuku's thoughts were cut short as Ochako strolled up to him.

"Hey, Deku!" She said happily as Izuku greeted her. She was wearing her hero costume and Izuku was still trying not to stare.

"H-Hey Uraraka!" Izuku said, blushing as Iida began to talk about the bus's seating arrangements. Unfortunately for the class president, the bus was not the conventional kind he was planning for. Iida stared at the bus in defeat as they began to board it. Izuku looked at him and almost chuckled at his expression.

Izuku took a seat next to Tsuyu and Sato as he began to fidget with the Omnitrix, excited for the Rescue Training. Mina put her hands behind her head as she began to speak.

"You know Iida, you really gotta chill man," Mina said as he stared at the stiff Class Rep. Tsuyu put a finger to her cheek as she spoke up.

"Y'know if we're stating the obvious, can I say something? It's about you Midoriya" Tsuyu said, pointing at him as he looked at her confused.

"Huh?" Izuku asked as Tsuyu continued.

"Your quirk is really weird." Tsuyu said matter of factly as Izuku began to sweat.

"H-Huh? Ye-Yeah I guess you're right?" Izuku said as the rest of the bus looked at him.

"Yeah man, like seriously you can pretty much have a transformation for every situation from what I've seen. How many do you have?" Kirishima asked as Izuku replied nervously.

"U-Uh.. 29. And counting." Izuku said as Kaminari let out a low whistle.

"Sheesh. Your quirk is broken man." Kaminari said Izuku shook his head.

"W-Well not really. I can only transform for 10 minutes, remember? And I'm basically quirkless for the next 10 minutes after. I also can't change forms without transforming back to normal and even then it drains my time limit." Izuku explained as Kirishima nodded.

"Yeah, now that you say that, that is a really big drawback. Still, it must be great to have such a flashy transformation quirk. My hardening might be useful in a fight but it doesn't look all that flashy." Kirishima said.

"No way! Your quirk looks pretty awesome. You're definitely Pro Hero material." Izuku said, holding up a thumbs up.

"Seriously? It seems like it'd be easier to be a Pro if I had a flashier quirk." Kirishima said as Aoyama interjected.

"My navel laser is the perfect mixture of flashiness and strength," Aoyama boasted as Mina looked at him warily.

"But it's pretty lame if it gives you a stomach ache sweetie," Mina said as the blonde boy's smile faltered.

"Well, if anyone here has pro quirks, it's Todoroki and Bakugou," Kirishima said as the rest of the class nodded.

"Yeah, but Bakugou's angry all the time so I doubt he'd be popular." Tsuyu said as Bakugou sprang up from his chair.

"What the fuck did you say Frog Bitch!" Bakugou yelled as Tsuyu pointed at him.

"You see?"

"You know we all basically just met you and we can already tell you have the personality of a flaming dumpster," Kaminari said as Bakugou glared at him angrily.

"You say something blonde bitch!? I'll kill you!" Bakugou yelled as Izuku stared on in confusion.

'Bakugou being unpopular? This school is really confusing.' Izuku thought as Aizawa began to speak to the class.

"Hey, stop arguing we're here," Aizawa stated as they arrived at a dome-shaped building. It was huge and had different disaster zones waiting inside. Izuku and his classmates stepped off the bus to go inside but a person was waiting for them.

"Thirteen?!" Izuku yelped as the rest of the class looked in awe. Izuku looked at her and spotted a familiar badge on her helmet, the symbol of the plumbers. She looked at them all and held her hands out.

"Hello, everyone!" Thirteen said as Ochako began to nerd out.

"Woah! Thirteen! She's one of my favorite heroes!" Ochako said as Thirteen threw a thumbs up.

"Well, I'd hate to keep you all waiting! Let's get inside!" Thirteen said as they made their way inside the dome-shaped building. The class gaped in surprise at the sight before them. It was like an amusement park except all the rides were disaster zones. Izuku grinned as he looked at everything before him. There was a shipwreck zone, a landslide zone, a fire zone, a squall zone, and more.

'Seriously, where does U.A get the funding for all of this!' Izuku thought as he looked around.

"I made this training facility to help prepare you all for different kinds of disasters!" Thirteen exclaimed proudly as the rest of the class still looked in awe.

"It's called the Unforeseen Simulation Join! The USJ!" Thirteen said as the entire class thought the same thing.

'Just like Universal Studios Japan'

"Shouldn't that oaf be here already?" Aizawa asked Thirteen who looked at him rubbing the back of her head and leaning into his ear.

"Apparently he did too much hero work today and he used up all his power for today. He's resting up in the teacher's lounge." Thirteen said as Aizawa sighed.

'It's fine, we should be able to do this with only us 2.' Aizawa thought as Thirteen began to speak again.

"But first," Thirteen turned back to the class, "I have a few things to tell you. As you all know my quirk is a powerful one. It's called Black Hole. I can use it to suck up anything and turn it into dust."

"Yeah! You've used Black Hole to save people from tons of disasters!" Izuku exclaimed as he began to nerd out with Ochako nodding her head vigorously.

"That is true. But my quirk can easily be used to kill people. Some of you here also have quirks like mine which are very dangerous. In our world, quirks are heavily monitored and regulated so it's easy to forget how deadly some can be. I hope you all know that if you make one mistake in the heat of the moment, you can kill someone." Thirteen said as the class looked at her grimly.

Izuku agreed with this and remembered that all his forms can kill someone too. With his amount of aliens, he could imagine all the different ways he could mess up and kill someone by accident. He could char someone too close to him to a crisp with Heatblast, somehow step on someone as Way Big, punch too hard as Four Arms, or even just accidentally give them hypothermia with Articguana.

Izuku shuddered as Thirteen continued, "You all have a solid idea of your quirk's potential and because of All Might's combat training you all probably experienced how dangerous some of your quirks are when used against other people. Carry those lessons over to this class because today you'll be learning how to use your quirks to save people's lives. You'll be using them to help, not hurt or injure. After all, that is what being a hero is all about."

"That's all I have to say, thank you so much for listening." Thirteen said bowing as the class clapped at her speech.

"Great, now that that's over we can-" The lights around the building began to flicker as the class looked around confused. Aizawa eyed the building, seeming just as confused as the class. Suddenly a mist-like portal began to open up in front of a fountain, behind Aizawa. Aizawa turned around and glared at the man exiting the portal. He had pale skin and grayish-blue hair. His face was covered by a hand as he exited the portal, his eyes gleaming red through the hand on his face.

The class looked at the scene confused as Aizawa shouted.

"Stay here and don't move! Thirteen! Protect the students!" Aizawa yelled as Kirishima looked at the portal near the fountain in confusion.

"Woah! What is that thing?" Kirishima asked as Izuku felt a chill go down his spine.

"Wait, has the training started already? I thought we were rescuing people?" Kirishima asked as he looked ahead to the mob of villains exiting out of the portal.

"Stay back! This is real! Those are villains!" Aizawa said as he put on yellow goggles over his eyes. Suddenly a big behemoth walked out of the portal, it looked almost as inhuman as one of Izuku's aliens. Its brain was exposed and it was incredibly muscular. It also had a beak with an array of sharp teeth.

"How strange, the only heroes I see here are Thirteen and Eraserhead. According to the schedule we retrieved from U.A, All Might should be here." The mist said as Aizawa glared at them

"So you scumbags used the press as a cover and sneaked onto campus?" Aizawa said as the man covered in hands began to speak.

"Where is he? I brought so many friends here who would love to meet him." The pale man said, gesturing to the villains around him.

"Maybe if I kill a few brats, he'll come out to play." The man said as Aizawa's capture weapon unfurled and his hair stood up.

"Real villains? Ho-How did they even get in here?" Kirishima exclaimed as Momo began to walk up and speak as well.

"Thirteen? Why are the alarms not going off?" Momo asked as Thirteen looked around the building.

"I'm not sure." Thirteen said as Todoroki spoke up.

"Is the entire campus under attack or are we the only targets? Even so if the alarms aren't going off it's probably the work of a quirk. They carefully chose this facility to infiltrate when a class was being taught. They're stupid for trespassing here but they thought this out." Todoroki said as he gazed at the villains below them.

"Thirteen! Get them out of here and alert the main campus. Damn it, wait, if they're jamming the alarms then they're probably jamming our communication too. Kaminari, try to use your quirk to contact for help." Aizawa said as Kaminari nodded and tapped the communication on his ear and began to fiddle with the knob on his belt.

"Sir! You can't fight them on your own! There's too many of them! Your fighting style isn't suited for this. You do best in stealth and one on one fights. You can't do too much fighting a group!" Izuku exclaimed as Aizawa turned to look at his opponents.

"You can't be a Pro Hero if you only have one trick. You of all people should understand that." Aizawa looked to the Omnitrix as he nodded to Thirteen.

"I'll leave this up to you Thirteen!" Aizawa yelled as he jumped down the stairs, unfurling his capture weapon as he ran towards a group of villains.

The villains aimed their quirks at them but were shocked to find that they couldn't use them. Aizawa's hair stood up as he grabbed them using his capture weapon and flung them away.

"You idiots! That's Eraserhead! He can cancel your quirk by just looking at you!" A voice said as someone else spoke up.

"Cancel quirks huh? Bet you can't cancel a heteromorphic type like me!" A man with four arms charged at him and tried to punch him with two arms but Aizawa dodged it and clocked him in the face, throwing him back as he threw out his capture weapon to grab his leg.

Aizawa quickly dodged a punch from behind, kicking his assailant in the face, sending him back to two other villains behind him. Aizawa released the capture weapon from the villain's leg, making him crash down to the 3 villains behind him.

"What a pity, I hate it when Pro Heroes live up to all the hype." The pale man covered in hands said snarling as he looked at Eraserhead.

"I guess I shouldn't have underestimated him." Izuku thought Iida shook him from his amazement and yelled at him to get moving. Izuku and his classmates began to run for the exit as the guy covered in mist teleported in front of them. The class gaped in shock as the man introduced himself.

"Hello, it's a pleasure to meet you, we are the League of Villains. I know it's quite impolite but we decided to invite ourselves into your little class lesson to say hello. Now, where is All Might so we can kill him? I believe he was supposed to be here today?" The man in the mist asked as the class stared at him in shock.

Before Thirteen could pop her Black Hole, Kirishima and Bakugou raced forward towards the villain. Bakugou let out a huge explosion in front of him as Kirishima hardened his arm and slashed forward.

"Did you really think that we were just gonna stand around and let you destroy this place?" Kirishima said grinning, holding up his hardened arm. Izuku coughed, everywhere was covered in smoke as he looked at what had transpired.

The villain appeared out of the smoke, seemingly perfectly fine as he began to speak. "You live up to your school's reputation. But you should be more careful, otherwise, someone here might get hurt."

Thirteen popped her black hole as she glared at the villain.

"You two! Get out of the way!" Thirteen yelled as the villain released a storm of mist at them. The mist covered everyone as Iida struggled to help his classmates out of it. Soon, the mist formed into a sphere of black, encasing the other students within it.

Izuku found himself falling as he somehow got teleported to the shipwreck zone. Before he could hit the water, he scrolled through the dial of the Omnitrix and slammed down, hitting the water with a splash as he was covered in green light.

In his place was a gray fish-man with an angler on his forehead, with a thick row of sharp teeth. The shark-like villain who was about to ambush him swam away in fright of the creature, fearing for his life. Ignoring the villain, Izuku began to think about what had just happened

'Water… that villain must have a warping quirk.' Izuku thought as he quickly swam to the ship in the vast body of water. He was naturally adept at swimming in the water, zooming past some of the other villains as he swam to the ship. Izuku was incredibly grateful that the Omnitrix had given him the form he had needed… otherwise, he couldn't imagine fighting these villains as Gray Matter or Ditto. Finally, he reached the ship as he used his claws to dig into the ship's metal exterior as he climbed aboard, slapping the dial on his chest, returning to normal.

As far as he could see he was the only one in the shipwreck zone which was concerning. That meant no one could help him. Izuku gulped.

'The villains knew our schedule and were after… All Might. Who isn't even here. They blocked communications and the exit so there's no way to escape. No one on campus even knows what's happening. And to top it off, I'm alone to fight a bunch of villains.' Izuku thought as he peered over the edge of the boat.

Suddenly villains were zooming towards the boat, ready to make Izuku mincemeat. Izuku grimaced as he looked down onto the Omnitrix. He couldn't transform this soon after turning back or else he'd have 5 minutes instead of 10. The reason he had turned back in the first place was that Ripjaws would've suffocated pretty quickly and he couldn't risk being in the water with all those villains.

Suddenly he heard a beep on the Omnitrix, signaling it was ready to use with the full time limit.

'What? I usually have to wait 5 minutes to transform without the penalty after turning back.' Izuku thought as the villains drew closer. Immediately he dialed the Omnitrix, hovering over Articguana so he could freeze over the entire lake. He slammed on the dial, disappearing once again in a flash of green light.

The light dimmed and in Izuku's place was not Articguana. He looked down at his arm which was now black and slender. He had plugs at the end of his fingers, tendrils, and a single green eye

"Feedback?" Izuku asked, confused, matching the alien's description to one in the notes that Ben had given him. But the puzzling thing was that Ben had told him that Feedback had been removed from the Omnitrix after an encounter with an alien named Malware. So how had he turned into him?

'Wait if Feedback is back in the Omnitrix… then does that mean that-' Izuku shook his head as he began to make a plan.

'I've got to get my head in the game. I won't die, not here, not now, not until I achieve my dream.' Feedback thought as one of the tendrils pointed to a source of electricity on the ship.

Feedback grinned.


"Shoji! Are there any signs of our other classmates!" Iida yells as Shoji's multiple limbs look around the USJ.

One of Shoji's mouths said, "They've been scattered across the facility, but they're still here." The group let out a sigh of relief at that statement.

"Well, what do we do? That guy is immune to our physical attacks and can teleport!" Sero asked as Thirteen looked deep in thought, her hands fiddling with a badge with an hourglass on it.

"Class Rep! I have a job for you. Run to the school and get reinforcements. The alarms aren't sounding and all our communication devices are useless right now. Even with Eraserhead canceling quirks left and right, we're still sealed out of the outside world. Whoever's causing this probably hid as soon as they got warped here. It'd take too long for us to find them. It'd be faster if you ran and got help than to find whoever's jamming our signals." Thirteen said as Iida looked mortified.

"Y-Yes! Bu-But it'd be cowardly of me to leave all of you her-" Iida was cut off as Sato cut him off.

"Go! There are a lot of alarms outside. That's why they're keeping us trapped here in the USJ." Sato said as Sero got into a fighting stance.

"As long as we keep him off your back and you can get outside, he can't follow. Speed past this mist with those engines of yours" Sero said as Thirteen spoke up.

"We'll provide support, kero." Tsuyu said as she crouched down, ready to attack.

"Use your quirk to help people. Be a hero Iida!" Thirteen encouraged the boy as Ochako smiled at him.

"I can help you like I did in the cafeteria! You can do it!" Ochako said as Iida got into a running stance and his engines popped out.

"Do you really think it's smart to talk about your plan in front of your enemy?" The man in the mist asked as he fired tendrils of black and purple smoke at them.

"It won't matter when I'm done with you!" Thirteen said as her Black Hole activated, pulling the mist away and disintegrating it into atoms.


Feedback looked around the ship and saw villains surround him in a circle. He grimaced as he tried to absorb as much electricity he could through his plugs and tendrils. Before he could absorb the last of it, a huge hand-like water construct cut the boat in half.

Feedback clung to the boat as it began to sink. The villains below him began to jeer at him but Feedback had a plan. He had one shot at this but it was guaranteed to work.

Feedback climbed over the ship's edge, standing on top of it with a mad grin. The villains stared at him, the grin never leaving his face as the villains laughed.

He jumped off the ship and took a page out of Bakugou's book and began to thrust himself past the villains using energy from his fingertips to rocket him forward past the villains. The villain with the water construct from before tried to slap him out of the air with another hand but Feedback veered left to dodge it, being careful not to electrocute the river.

"Now I know why Ben loved this alien so much! Feedback rules!" Feedback exclaimed as he flew to the edge of the shipwreck zone. After approaching the shore, he deactivated the electricity in his fingertips and readjusted his hands to point to the ground as he activated it again to safely land. Feedback landed with a thud as he kicked up dust around him. The villains were slowly approaching him, swimming to him.

Feedback's grin faltered. He couldn't electrocute them, not when they were in the water. No matter how much he regulated his output, one wrong move and he could fry an entire group of people. He couldn't fight them until they were on solid ground.

Feedback raised his arms in a fighting stance, scanning the area as a huge shark man jumped out of the water, widening his jaws to take Feedback's head off. Thinking fast, Feedback stuck his tendrils onto the man's skin, sending a small shockwave through his body as he screamed in pain before falling unconscious.

The villains still in the water looked at him, grinning as they began to regroup.

"So you're just a taser huh? I'd like to see you take all of us!" One of them yelled as all the villains rushed to the shore as Feedback got ready. All the villains exited the water with their quirks out as feedback looked at where their feet were.

Solid ground.

Feedback's grin grew wider as he placed his hands and tendrils on the ground and yelled,

"Improvised Super Move: Feedback Loop!"

Arcs of electricity raced on the ground as the villains stared in shock. They all screamed in pain as the electricity entered their system. Feedback sent out the electricity and reabsorbed it every few seconds as the sparks danced across their bodies. Soon they all went limp and fell unconscious.

Feedback breathed heavily as he looked at the scattered bodies around the shore. He tried to output the least amount of electricity he could since most of them would still be wet from exiting the water. He raced to one of the bodies and checked their pulse. It was beating.

Feedback breathed a sigh of relief as he took in his surroundings and began to form a plan, deciding to stay in the water to hide from the villains.

'If I follow the shore to the exit, I can avoid the central plaza entirely.' Feedback thought as he looked at the central plaza where his teacher, Eraserhead, was still fighting the villains. Feedback didn't know how long his teacher could keep going but he knew he couldn't keep going for long. Finally, an idea popped into his head.

'I can't just leave him alone! He needs my help... But I have to think about this logically. I'll step in if he needs any help, plus the Omnitrix should be timing out pretty soon so I can't just rush in.'

Aizawa began to ready himself as the pale man with hands all over him raced over to him. Aizawa unfurled his capture tape and shot it forwards towards the man trying to subdue him.

The villain grabbed it as he and Aizawa raced forward. Aizawa grabbed the capture tape again as he elbowed the villain in the stomach. The villain grabbed Aizawa's elbow as he struggled to get it free. Suddenly, his hair fell, signaling that his quirk got deactivated.

Feedback gazed on in horror as Aizawa's elbow began to disintegrate. Aizawa pulled away with a pained grunt as he began to fight other villains, taking them out of the fight one by one as the man covered in hands watched.

Soon enough he was the last one standing and the villain who had disintegrated his arm held out his arms.

"You really are so cool, Eraserhead. Oh, but by the way, hero… I'm not the final boss." Suddenly the huge muscular bird monster with an exposed brain appeared behind Eraserhead as Feedback looked on in horror.

Before he could make his move to help his teacher the Omnitrix began to beep and flash red.

'No! Not now!' Feedback thought as he disappeared in a flash of red light, catching the eye of the villain who was about to send the monster at Aizawa.

"Now what is this? A student?" The man said with disgust as Izuku triple tapped the Omnitrix faceplate and leaped up from the water. He knew this was basically suicide but he couldn't just stand there and do nothing.

"Get your hands off Mister Aizawa!" Izuku yelled as he held up his blaster and dropped his skateboard on the ground. He kicked his feet off from the ground, barreling his way towards the villain, holding up his gun.

"Nomu, kill that brat!" The villain yelled as the Nomu in a quarter of a second appeared in front of Izuku. His hands were raised, about to crush him but Izuku was fast. He reacted quickly and swerved past the attack on his skateboard, pelting the Nomu with laser blasts that stunned the Nomu in its tracks.

'I might not be able to use the Omnitrix but that doesn't mean I can't fight!" Izuku thought as he swerved away from another one of Nomu's attacks.

Unfortunately, he couldn't keep this up forever, the only reason he wasn't dead was that the Nomu lacked intelligence and couldn't properly attack him. The Nomu raised another one of his fists, aiming directly for Izuku's head as he began to panic. Izuku knew he couldn't swerve away in time so he jumped off the skateboard, rolling away on the ground as Nomu smashed the board to bits. With no way to outmaneuver the Nomu anymore, Izuku started shooting the Nomu repeatedly, making it stagger back as he ran around it.

Whatever the blaster shot out was powerful enough to paralyze the Nomu but since it was only set to stun it was more of an annoyance than a real obstacle. Izuku ran around the Nomu as the villain glared at him.

"Nomu! Stop playing around! Kill the brat before I do it myself!" The villain yelled as he thrust his hand forward to try and touch Eraserhead with his decay quirk. Izuku's eyes widened as he began to run forward towards his teacher, ignoring the Nomu behind him as he shot it with lasers. Eraserhead's hair stood up, canceling the villain's quirk as all 5 of his fingers touched Eraserheads face.

"No!" Izuku yelled as he intercepted the both of them, wrenching the villain's hand off Aizawa's face and dropping his blaster. Aizawa stared on in shock as the villain grabbed Midoriya's left arm, where the Omnitrix resided.

Aizawa's hair fell.

The villain grinned as he waited for Izuku's arm to disintegrate but the universe had other plans. Izuku's body began to rapidly change, first Heatblast, next Wildmutt, then Diamondhead as the villain stared on in shock.

Izuku turned into XLR8, Gray Matter, Four Arms, Stinkfly, Ripjaws, Upgrade, Ghostfreak, Cannonbolt, Wildvine, Blitzwolfer, Snare-oh, Frankenstrike, and Upchuck in a span of a second as an entire beacon emanated from Izuku, showering the entire USJ in green light.

"Wh-What are you?!" The villain yelled as he began to transform even faster. He became Eye Guy, then turned into a quarter of the height of Way Big before he transformed again, this time into Spitter, then Buzzshock, Articguana, and finally Feedback as Izuku grinned.

"I'm Izuku Midoriya and I want to be a hero!" Izuku said as he transformed into Lodestar and lastly, Swampfire. Swampfire grabbed the villain's arm and shoved him back as his arm began to disintegrate. Swampfire quickly chopped his arm off, the limb falling to the floor as it disintegrated completely. With his arm quickly regrowing, Swampfire quickly covered Aizawa in the toughest vines he could, forming a protective barrier around him. Another flash of green light enveloped Izuku as he turned back to normal.

Izuku stood tall as he slung his hand in front of Aizawa's protective barrier as if to protect it. The villain laughs.

"Nomu! Kill him!"

"It's hero time!" Izuku yelled as he slammed down on the Omnitrix. His body felt like it was melting, disappearing under a green flash. The flash dimmed and in Izuku's place was a large being in a containment suit with three slits to let the alien see. Izuku stood his ground and the villain scoffed.

"You're gonna beat Nomu with a tin can? You're not the right level for this hero!" The villain yelled as Izuku raised his arm and braced himself for the punch from Nomu. The Nomu cocked his arm back as it made contact with the metal exterior of Izuku's containment suit, the sound of it resembling a bell being rung.. The Nomu growled in pain, its fist bending from the durability of Izuku's exterior as the villain yelled in anger.

"What are you doing? Break his armor and kill him!" The villain yelled as the Nomu unleashed wave after wave of punches at him. The containment suit simply brushed off the impacts like they were nothing as the Nomu's hands became deformed but regenerated after each hit. Izuku's metal feet dug into the ground as he withstood the impacts and took notice of Nomu's healing.

'Regeneration? Damn it, I need to think of a plan.' Izuku thought as he sidestepped Nomu and threw a punch at it. Surprisingly, his fist seemingly just bounced off. Izuku looked on in shock as Nomu grabbed him and slammed him down to the ground.

Izuku stood up and threw up his arms as the metal containment suit began to glow red hot with his anger and determination.

"I can do this all day."


"Ah, Black Hole, the quirk that sucks up matter and turns it into dust. What a destructive quirk. However you're a Rescue Hero Thirteen, combat isn't your forte!" The man in the mist yells as he sets up a portal behind Thirteen so she would use her quirk on herself.

Acting fast, she disables her quirk and rolls away from the villain. She grabs a badge with an hourglass symbol as it begins to transform into a futuristic gun, while Izuku's looked like a pistol, this gun looked to be an honest to god energy cannon.

"Wh-What? How!" The villain yells as Thirteen smirks from under her helmet, pointing the energy cannon to the villain. The students looked almost as shocked as the villain, looking at their teacher's weapon.

"Get your hands off my students!" Thirteen said as she fired the gun, aiming for the brace on the villain's neck. Acting quickly, the villain creates a portal to send it back to Thirteen but the blast seemed to curve around it. The energy blast hits the villain's brace, making him stumble back

'I-It's tracking me!' The villain thought as Thirteen fired another shot at him as she yelled at Iida.

"Run! Get help!" Thirteen kept firing at the villain, each blast sending the villain staggering forward. Acting fast, Iida began to run for the doors as the villain yelled in anger

"No!" The villain slipped from Thirteen's battle and made his way to intercept Iida. Shoji grabs the mist, trying to capture the villain as he breaks out and continues to race towards Iida. Immediately, Sero and Tsuyu lash out, grabbing the villain as Ochako races to touch his metal brace.

"Now!" Ochako activated her quirk as she touched the brace on the villain's neck as Sato grabbed him by Sero's tape and swung him around like a lasso. Sato throws him as hard and as far as possible as Iida reaches the door and pries it open to get outside.

Iida dashes out from the USJ entrance, bolting to U.A as fast as he could.

Suddenly a huge green beacon emanated from the central plaza as the students gazed down in curiosity Ochako and everyone else gasped in shock as Izuku began to rapidly transform through his various aliens before wrenching the villain's hand off his arm and protecting Eraserhead in a vine barrier.

"It's hero time!" They heard Izuku's yell reverberate across the entire USJ as he was gone in a flash of green light.


'Damn it, none of my hits are scratching him.' Izuku thinks as he punches Nomu again, its hits bouncing off the monster's skin, charring a bit from the heat emanating from his suit but that quickly mended. The villain laughs from under the hand covering his face.

"It'll take more than that to hurt Nomu! He has shock absorption!" The villain cackled as Izuku's mind stopped and registered that fact.

'Shock Absorption and Regeneration. Th-This thing has 2 quirks!' Izuku thought as the creature threw another punch at him which didn't hurt the alien in the slightest. But Izuku knew he only had a few minutes left before the watch timed out.

Izuku felt the inside of his suit burn as a realization washes over him. The heat he was giving out… it didn't feel like Heatblast's heat. This heat felt… radioactive. Could it be that his powers involved radiation? Izuku yelled as he let out some of the energy in his body, a laser shooting out of the three slits in his armor as Nomu howled in pain. His body became charred and deformed from the laser, a clean hole through his chest but the damage regenerated quickly.

Izuku remembered something about quirks, something that he knew was a fact. Quirks were bodily functions meaning they had a limit. Every quirk could be exhausted in some way shape or form. Which reminded him of something Bakugou said in the battle training.

'I need to kill him faster than he can mend' Izuku thought as his entire suit glowed red with heat. He felt all the energy in his body, the geyser of radiation bubbling inside his suit as he grabbed Nomu and pinned him to the ground. It was difficult to pin him down but Izuku clawed for the radiation to escape his body.

Izuku screamed as he focused all the energy in his body into a single blast as the Nomu yelled and thrashed below him.

"Improvised Special Move: Nuclear Meltdown!" Izuku yells as he pours out all the heat and radiation in his body in a massive blast completely decimating the ground below him and Nomu as a result. The ground was melting and the air was scorching hot. The villain backed away from the crater containing his Nomu and Izuku as the mist villain appeared next to him. The Omnitrix began to beep and flash red as the villain covered in hands glared at him

"Shigaraki, it's time to go. The Pro Heroes will be here soon." The mist villain said as Shigaraki yelled in anger.

"He cheated! He killed Nomu! Nomu can't be beaten by some brat! I'll kill him!" Shigaraki yells, running and thrusting his hands forward to kill Izuku just as the door of the USJ flew open.

"Have no fear! For I am here!"

A/N: And that's the chapter. It took longer than usual due to the number of ways Izuku could have fought the villains and I had a hard time deciding what aliens to use. The aliens I wanted to fight Nomu were either Goop, NRG, Swampfire, or Humongosaur. I decided on NRG because he is one of my favorite aliens and would definitely defeat Nomu with deadly efficiency due to his radiation.

Also, Feedback and Ghostfreak are in the Omnitrix. Will Izuku ever use Ghostfreak? Maybe, maybe not. I'm debating on whether to have him show up soon but if he does you can probably guess who Izuku is gonna use him against. I want to him to be there to kind of scare Izuku a bit since he knows what happened to Ghostfreak in the OS. He'll be there just to kind of put him on edge every time he transforms since he'll never know if he'll accidentally mistransform and become Ghostfreak. He'll eventually have to face that fear though.

As for why Tsuyu wasn't dropped into the shipwreck zone, I thought it'd be easier to write the chapter without her and I think I was able to show off Izuku's capabilities more as a result

Thirteen being a badass and pulling out an energy cannon is since she's a Plumber. She isn't a Max Tennyson but I would believe she'd be well trained and able to hold herself in a fight if she was involved in galactic law enforcement

Also my if you didn't notice, Izuku cycled through the original aliens in order of appearance and cycled through his new transformations in the order of appearance in this story.

I don't know Shigaraki's decay quirk works, but I don't think Diamondhead would be immune to it just because his crystals don't age. I'm under the assumption that he doesn't age things forward but just pulls them apart? But Swampfire would easily be immune to Shigaraki's decay, atleast this early on since Aizawa didn't just straight up disintegrate from one touch to his elbow. I don't know if that's right but that's the logic I followed on why the Omnitrix didn't just keep him as Diamondhead. Also if you're asking why Izuku didn't just phase when he turned into Ghostfreak, he was already being gripped by Shigaraki so it wouldn't have mattered I'm pretty sure.

Review Responses:

Doctor3207: That is actually a really good idea, I might be using it in the future chapters. I really liked Ship in Alien Force so I would love to incorporate him into the story. Also yeah sorry but Ghostfreak's in the Omnitrix.

Anyways, until next time everyone.
