Furor Mecanica at USJ

AN: Quirk from the first chapter.

"I guess I should use this form." Izuku mutters as he switches to a smaller and more feminine form.

"I thought you stayed in Sentinel form because it was the most human-like?" Tsu asks from her seat next to the robotic student. "This is much more human sized."

Indeed the body was almost half a meter shorter than the sentinel and was much less bulky.

"Because this form isn't male." Izuku answers in a feminine voice.

"I see." Tsu says.

"You can turn into a girl!?" Mineta shouts, "Show us your..."

Before Mineta could finish his vulgar request he was knocked out by Kyoka.

"How disturbing." Momo comments.

"What can that form do?" Mina asks curiously.

"This form, the Adept, is much more agile, and has a psionic transfer ability. But I chose this for rescue since it's much friendlier looking than anything else I can do." Izuku explains.

"I want to see you in action!" Mina shouts, "See if you can dance!"

"Ok then." Tsu says, concerned about the amount of energy coming from the pink skinned girl.


It turns out, being in his adept form was quite lucky. Izuku was able to psionically transfer onto the boat in the flood zone instead of just sinking. He could have fought from the bottom of the lake, but his classmates might jump in to look for him and get hurt.

"I have an idea." Izuku says after some discussion about what to do. "I switch to my disruptor form and detonate above the water, creating a vortex where Mineta's quirk can stick them all together."

"Then we escape?" Tsu asks.

"Indeed, grab Mineta and flee, I will follow." Izuku says. "Also, my disruptor form can cloak so don't expect to see me until you reach shore."

"Sounds like a plan." Tsu agrees and slaps Mineta, causing him to freak out and begin throwing his quirk into the water randomly.

In a flash of light Izuku transforms into a large floating ball of light with metal plates orbiting around it. "We begin anew." A male voice resonates from within. The ball then glows brightly before sending a ball of said energy towards the villains in the water.

The explosion vaporizes nearby water and causes an implosion, sticking all the villains into a neat ball.


The three students gather at the edge of the lake, Izuku returning to his adept form as he arrives, scaring Mineta who hadn't remembered his previous form could cloak.

"Quite." Izuku's feminine voice commands. "We should get out of here."

"Let's head for the bushes." Tsu says, moving quietly through the water.

Sadly, despite it being essential for a hero with his quirk, Mineta had never invested time in learning how to sneak about. So he slashed through the water like someone twice his size and made more noise than even the robotic Izuku, who was more than twice his height and many times his weight.

This nearly got Tsu killed as the hand-covered villain raced forward and would have killed her if Aizawa didn't stop his quirk. Izuku followed this up by sending his psionic transfer though the villain, stunning him temporarily before following this up with a glaive. Unfortunately the big brain villain blocked the glaive and the fight was on.

All Might soon arrived and within seconds only the leaders were left standing.

"Stand back young Midoriya, I will take care of these villains!" All Might shouts.

"Negative All Might, I have engaged in glorious combat and will not be retreating." Izuku replies proudly.

"You could get hurt." All Might claims.

"To kill me they would have to destroy all my forms. And that is not possible." Izuku responds.

"Still." All Might adds lamely.

"Not even you could beat my best forms, these chumps don't have a chance." Izuku insists before launching a glaive at the hand villain, forcing the warp villain to block once All Might engaged the Nomu.

The fight continued for a few minutes as a stalemate, All Might unable to beat Nomu and Izuku easily kiting the other villains.

"Enough!" The handsy villain shouts, "Kurogiri, Nomu, do the thing!"

Suddenly Nomu makes a blatant but powerful attack, creating an 'opening' that All Might exploits, suplexing the villain... right into a portal.

"All Might!" Izuku shouts.

"SHIT!" All Might shouts as he is grabbed.


The timely arrival of Todoroki and Bakugo solved that situation, but the fight was still on.

"This time you really should stay back." All Might orders, preparing for an epic showdown.

"No, this time, gloves are off, I'm switching to a powerful form." Izuku insists before a glowing golden light engulfs him and the massive body of his immortal form appears.

"Our cannons shall sing!" Izuku booms, "I will take this Nomu." he claims before his powerful cannons open up and begin tearing Nomu to pieces.

"Nomu! Kill him!" The hand villain screams after the barrage stops and Nomu regenerates before throwing a punch that sends everyone, except All Might, flying.

Once the dust had settled, everyone could only stare in shock. The punch that had pushed All Might back earlier, had not even moved Izuku. He just stood there calmly and aimed his cannons. "Woe to our enemies." Izuku says before blasting Nomu once more.

All Might just stood there and stared at the complete destruction of Nomu, its regeneration unable to outpace the cannon's damage.

"Regeneration can't last forever, but I can." Izuku claims as he continues the barrage.

After recovering from the shock of Nomu being beaten so easily, the hand villain shouts "Kurogiri, dump him in the lake!"

And soon enough a portal appears below Izuku and his cumbersome form is unable to dodge. After he disappears into the portal a mighty splash is heard from the lake.

Soon Nomu regenerated and charged once again, but All Might wasn't sitting idle this entire time. Using his righteous anger at this attack he vanishes from sight. Appearing below Nomu instantly All Might throws a punch beyond what had been seen before, sending Nomu through the roof as the UA staff arrive.

"I return with a vengeance!" Izuku's immortal voice booms as he breaks the surface of the lake, marching towards the stunned villains.

"Tomura, it's really time to leave." Kurogiri insists as he glances at the many threats.

"Fine!" The man-child replies, but not before sneering at All Might. "I will kill you!" he claims before disappearing.

AN: A second installment to this quirk. Definitely my favorite that I've thought of here. OP but not ridiculous like some others. The funny thing is even such basic Protoss units are completely unbeatable. Colossi? Carriers? Any other air unit... yeah, good luck. The only weakness of the purifier faction is their lack of air splash, only Fenix's hero scout and his dragoon form have them but Izuku doesn't have access to those elite units, only basic purifiers. Lucky for us the swarm isn't a thing in this universe and most villains can't fly.

I have a few more ideas for quirks, and I'm thinking about how to do a nuke/Mensk quirk. Despite my dislike for Terrans, it has some potential as a quirk. Even if it would be the weakest shown yet, save perhaps for Primal Tsu...
