Izuku was having the time of his life.
Well, if he didn't consider the fact that villains had attacked his friends and that he was about to face off against the strongest of said villains.
Apart from that, his current situation was just swell.
He wasn't going to deny the fact he had maybe gone a little overboard, but he had never gotten his hands on such a big piece of technology, all the little pieces coming together as a whole, humming in a chorus that just begged the boy to make them into something more.
He'd let his inner nerd run wild.
What used to be the boat U.A probably used to simulate water based rescue missions was now an eight foot mech, crammed full of so many weapons that it probably had more firepower than the whole Mustafa police department.
The entire situation made Izuku want to screech like a fanboy, but he decided that doing so would likely not look very intimidating to his enemy.
Speaking of, the green haired boy idly noted how the hand he'd cut off had grown back in the short time it had been.
So Nomu had regeneration.
Could be worse, there were a few ways around that kind of quirk, the real question was how strong the regeneration actually was.
Izuku crossed his mechanical arms as the black creature rushed towards him, fist cocked back for a punch.
Before the powerful blow could land, however, it was stopped by a green shell like structure made of hexagons, a hardlight shield, the boy thought it would do him some good to add a version of it to his hero costume, but he couldn't figure out how to make it small enough yet.
Despite the creature's impressive strength, Izuku barely shifted backwards thanks to his technology, Izuku loved Upgrade so much.
The two opponents stopped for a moment, locked in a silent struggle as Nomu tried to force Izuku backwards with sheer strength, seemingly confused as to why the boy hadn't moved.
It was during this brief respite that Izuku caught on to something, there was no light in his opponent's eyes, no spark of intelligence, it was as if he was a puppet made to follow orders, no better than a machine made of meat.
Unfortunately, said machine had been ordered to kill the boy, and he knew enough about machines to be sure that the black creature wouldn't stop unless one of three things happened, it completed its mission, the success of which Izuku personally wasn't very fond of, it got new orders, which seemed unlikely since the one giving it orders seemed very pissed at the greenette, or it got defeated so badly it couldn't keep fighting.
This was the only viable option to ensure Izuku's survival, the boy knew as much, except he wasn't sure if he could simply put the beast out of commission by beating it in a fight, the boy simply wasn't strong enough to be sure he could do that.
That was the problem, Izuku was still weak, he was a lot stronger than he was less than a year ago, but he wasn't strong.
If he was strong he could win all his battles without having to go too far, killing was not the tool of the truly powerful, those who needed to kill to stay safe were scared of the retribution of leaving their enemies alive.
Right now Izuku was terrified.
However, he couldn't win this fight without going all out, and that unfortunately meant the boy was going to have to fight to kill.
It left a bad feeling in his stomach, well, he didn't have a stomach right now, so it was more of a mental affliction, but between his own life, and the life of a possibly non-sentient being, Izuku knew what he had to do.
The greenette cocked his own fist back, a piston forming on his forearm, before delivering a punch straight to Nomu's face, the piston then kicked in, extending the fist enough to hit the creature a second time in rapid succession.
Any normal person would have had their cranium caved in by this, but the hulking mass of muscle barely flinched, in fact there wasn't even a sign that damage had been dealt.
'Some form of defensive quirk? But isn't his quirk regeneration, is it possible that this thing has more than one quirk?' Izuku thought to himself, this only further cemented his theory that the being before him wasn't human, Izuku quickly back stepped to move out of the way of another punch, this time forgoing the use of his shield in order allow himself to grab the offending arm with his own.
In his free hand, a hilt extended out of his wrist before a long four foot blade slid into place above the extending guard of his new sword.
In one swift motion Izuku cut off his enemy's arm.
The brutality of his own action made Izuku queasy, the feeling of his upgraded steel weapon shearing through the flesh of his enemy was nauseating, even more so when his own body was wrapped around the weapon.
Even though the boy had already confirmed the creature's ability to grow back lost limbs, the fact he had just cut something's arm off was borderline traumatic.
The boy steeled his resolve once more, the creature was here to match All Might at his full power, not only match him but beat and kill him, he needed to go overboard to survive.
Izuku barely noticed the lack of blood coming from his enemy's stump before a new arm burst out from it, almost as if it had never been lost in the first place.
The boy clicked his tongue in annoyance, he needed to put the monster down, but it was just shrugging off his attacks, he needed time to think of a way to permanently damage his enemy.
Creating a jetpack on his back, the boy boosted himself backwards at his enemies next attack, leaving the thing's range by a large margin, before a compartment opened up on both his shoulders.
The boy released a barrage of missiles onto his foe, not the concussive type of missile either, no these were made to blast a hole through the hull of a tank.
He watched as his opponent was seemingly unaffected by the chain of explosions, moving through it like it had simply been peppered by pebbles.
'Right it could probably take a hit from All Might…' Izuku thought to himself in annoyance.
Using the cover of smoke the boy had just created, he took to the air to gain some distance from the creature, hitting it with laser blasts from his one circular eye every so often to keep its attention on himself.
Usually the weakness of a regeneration type was fire, if the wound was cauterised then the afflicted would be unable to heal said wound without cutting away the burnt bits, the only issue with that was that his laser beams should have in theory been cauterising the wounds he inflicted anyway, but as the creature had shown with its wrist, that had not been an issue for it. Well perhaps his lasers weren't hot enough?
The creature did display a commendable amount of durability, so it would make sense that he would need much hotter lasers for any kind of cauterisation, except increasing the heat from his lasers would require some form of focusing chassis, which wouldn't be too difficult to make with the amount of components currently at the boy's disposal, but Izuku also questioned whether the laser would be exposed to the creatures flesh for enough time to ensure that the wounds would not heal.
Well there was a much more brutish solution than tactical orbital lasers strikes he supposed.
Turning his attention to his sword, Izuku willed it to change, instead of a large metal blade, the entire thing retreated into its hilt, before taking a cylindrical shape.
In the next moment a long thing blade of superheated green plasma shot out from the hilt of the sword.
'Note to self, make one of these on a smaller scale for untransformed use.' Izuku thought to himself, before he turned to face his opponent.
His other hand morphed into a rapid fire laser rifle that he used to distract his opponent by pounding him with fifty bolts a second to the face, as he dashed towards him with his jetpack.
The boy brandished his laser sword, leaving a streak of green light as he chopped off his opponents arm again, the highly concentrated plasma burning the stump a smoky black which would hopefully prevent it from regrowing.
The creature screeched into Izuku's robot face.
The boy was not amused.
Neither was the the watch interface on his chest as it started flashing an angry red.
Which was just great in Izuku's opinion.
The greenette recalled his stretched body parts, reforming Upgrade's body into its usual form as he sat in the cockpit he had made for the off chance that he needed to operate the mech in human form.
He'd gotten carried away, because, well he didn't have an excuse besides he was focusing all his effort in finishing the fight that he got tunnel vision, at least he had the foresight to make the thing functional outside of his transformed state.
Well, functional was a stretch, without any upgrades the thing was real rickety, it had terrible armour, and couldn't provide the energy required to power any form of energy weapon, which really left Izuku high and dry when it came to offence or defense.
It was built from pieces of a boat after all, not exactly prime mech building material.
But hey, the thing could float quite well, so maybe he could do that.
Float his enemy to death.
Izuku was knocked out of his musings as a powerful fist cave his hull in.
Well that was just dandy wasn't it?
The boy slapped his enemy away with his now defunct laser gun hand, before channeling the little power he had left into his sword so he could give his opponent one last fuck you shank.
It had not achieved much more than pissing his enemy off, but at this point the boy would take what he could get.
His opponents response was to grab both of the mech's arms try to rip them out of their sockets, a task which he was succeeding at with horrifying efficiency.
Izuku took a short pause to mourn the loss of his mech, truly one of his masterpieces, before he punched the big red button on the control panel.
The back of his mech opened up, shooting out the cockpit, sending Izuku across the plaza, before the robot overheated its engine and exploded right in his enemies face.
The self destruct sequence really should have killed anything that Izuku had been fighting, but Nomu seemed to just shrug it off with ease, which was both terrifying and extremely annoying.
Recognising the fact that he should probably run, Izuku began scrambling to escape his escape pod, which was quite ironic in the greenette's opinion, not that he had much time to think about that, as he heard the angry rant of the villain who had been holding his teacher hostage earlier.
"NOMU, GET ME OUT OF THIS STUFF AND THEN KILL THAT BRAT!"
That certainly did not bode well for the boy, so he decided to crawl out of his pod faster, upon doing so he risked a look at what his enemies were doing, only to see the black creature rip through the purple goo he had made using Mineta's quirk with its claw like it was tearing through wrapping paper, which just served to annoy Izuku even more about his situation.
On that note, Izuku decided to book it the best he could, maybe he could get away enough for the watch to go off cool down so he wouldn't be splattered on the concrete by the creature's hulking fists.
Running as fast as his legs could take him, which was fast enough to almost get him out of the plaza before a shadow loomed over him.
Izuku looked back in horror, eyeing the black creature as it lifted its arm up, fist ready to come down upon him.
He was dead.
The boy knew his demise was coming, and he could do nothing about it.
His regrets flitted through his head.
He regretted not figuring out all the secrets of the watch.
He regretted not achieving his dream to support the quirkless population.
He regretted not helping to prepare his friends for the world as much as he could.
He hoped his mother and his friends wouldn't cry too much over this.
Izuku Midoriya closed his eyes, ready for it to be the last time.
"It's fine now. Why? Because I am here!"
Izuku cracked open his eyes, looking at the towering figure of the man before him.
Damn All Might, always saving him at the last second.
He was definitely going to get traumatised at this rate.
