Chapter Text

Izuku Midoriya is born with a powerful mutation of his fathers quirk, he is capable of catching himself on fire and becoming stronger, both in offense and defense, but the flames can die out or be put out.

He is also able to breathe fire like his father, and while caught on fire the flames are both hotter and more powerful while reaching greater leangths and widths.

His greatest ability is while on fire and he takes a hit whether ranged or close range, his body sends out a condensed ball of fire that homes in on the person or thing that harmed him.

(Also yes I know that all of these seem like powers from Krieg from borderlands, that’s where I got the idea.)

In this world just before Izuku is born his parents gain the money to move out of Japan, they move to Ireland, where Izuku is born and gains a mutation quirk. His quirk gives him goat legs and horns like that of the mythical creature the satyr, later in his life his family moves back so Izuku can attend U.A. where he basically becomes the Pony tsunotori of class 1-a.

His quirk gives him increased speed and agility with bonus kicking power. (Basically letting him move like how he does in full cowling.)

He’s a pretty easy guy to get along with, although a bit loud at times while also using Irish slang/swears when he talks.

When Izuku gets his quirk, it is a strong telekinetic quirk allowing him to do all sorts of things (just think of all the powers from psychonauts) and he is soon found by agents Sasha Nein and Milla Vodello. He is taken to Whispering Rock training camp where he meets other children with psychic type quirks.

In this universe Izuku is caught in the middle of a villain attack, costing him his left arm from the shoulder down. So one day while walking past dagaboh municipal beach he has the idea of putting his intelligence to the test, and uses the scrap to craft a prosthetic robot arm that has the strength to break concrete. He than begins making a robot body of sorts, creating a new type of technology that helps make him and his mother more money, his mother names the robot deathtrap since it’s made of nothing but floating scrap from a junk yard.

Izuku still enrolls into the hero course his robot arm and deathtrap helping him secure points. He later makes a titan bot from titan fall, which helps in the USJ attack.

He also gets a side offer to do some work in the support course he accepts if just to make thing to help other people in every day to day life. Such as helping make hover tech for cars and trains.

In this world Izuku is still born quirkless, toe joint and everything, how ever it’s discovered that he has a very rare condition. One that cause him to grow scaly skin and his teeth and nails to grow in sharper, later in his life, thanks to all the bullying and abuse from others, it caused his mutation to accelerate making him twice as tall along with a tail that had begun to grow.

Izuku has all the strengths of killer croc from Batman.

Able to hold his breath under water for long periods while also swimming much faster.

He could very easily crush a small car and even bite through most metals.

His sense of smell has also gotten a boost allowing him to smell any nearby villains.

So we all know that Izuku’s dad can breath fire, but what if his dad was Hanzo Hisashi from Mortal Kombat. In this world Izuku would still be quirkless, but his father would train in him in both self defense and ninja combat along with how to use his famous spear.

Chapter Text

Izuku is born with the quirk to not only put people to sleep, from a small flame on his hand, but is also able to go in and out of the dream world.

In the dream world he can change and manipulate the environment.

Any damage he does to his opponent is done to them in the real world.

He has a gauntlet on his right arm with four long blades from the knuckles. (Think like wolverines but instead of in between the knuckles it’s on them)

With his power he catches the eyes of Midnight since she is able to put people to sleep but in a wider area.

Chapter Text

In this Izuku has the ability to summon various weapons, along with a durable armor. Things like pistols, shotguns, assault rifles, chain guns, and much more.

He is also able to increase his strength for a short period for a sort of berserk mode, or or to increase movement in his arms and legs to move and act faster. He can also focus an inner energy that he can apply to his armor or weapons to allow a small invincibility or damage boost.

Some of his favorite weapons are a double barrel shot gun, a chainsaw with the word ‘pain’ written on the balde, and a chain gun that can act as a mobile turret.

He can run out of ammo, but they replenish over time or he can physically make more to speed up the process.

Chapter Text

In this world Izuku’s mother and father do not have their canon quirks. Instead his mom has ‘maw’ which gives her a mouth full of enormous fangs. (Think mileena from mortal kombat x) His dad has arm blades, retractable blades that come from his forearms. (Think baraka from mortal kombat)

So Izuku has the quirk he calls ‘Savage’ which since he has his mom’s teeth and dad’s blades makes sense.

His blades and fangs can cut and bite through most weak metals, like iron but anything stronger he risks breaking a tooth. Even if they do grow back. Most of his moves revolve around jumping at a target and getting in close to tear them apart or just biting them until they give up.
