MHA Story And Quirk Ideas

Quirk: Solid Flames

Inko's Quirk is Manipluation of Small Objects. The same quirk, but a couple diffrent add-on functions. If she picks up an object that isn't fully solid, she can solidify it. She can also use a doll as if she were a puppiteer, hence the Quirk's name.

Hisashi's quirk is Fire breath, however it's closer to Creamation's firepower.

Izuku's quirk is Solid Flames. He inherited Green Flames from his father, and telenetic control and solidification aspects from his mother. He can expel them from any point of his body, and he is immune to fire as a result. They're basic flames, but he can up the fire power to levels above Cremation's. The hotter they are the greener more beautiful the color of his Flames get. He can telekenetically control his flames at any heat, however the hotter it is the harder it is and the longer it takes to solidify.

Solidification of his flames are tricky. If he's not careful he could solidify the whole flame column instead of the portion he wanted to. The hotter they get the harder and slower is to solidify. When they do they are difficult but not impossible to break free from. They still give off heat when they're solid, but they no longer burn unless Izuku wants them to. If the person is burnt and they touch the Solid Flame it agitates the burns and makes it hurt, the more severe the burn the more severe the pain. Solidification is permanent, meaning he can't unsolldify them. However, when his flames are solid water act as acid would to them. It hisses and wears it down. The hotter the solidified flame the slower the water works on it.

His full-power Solid Flames are stunningly gorgeous, especially if they're solidified. They look even prettier than the prettiest gems, and are more valuable than them too. Not only can they solidify to as strong as diamond in rare cases, the way they solidify makes them look like gems too. They also produce heat, but don't burn unless Izuku chooses for them to. That means they don't melt metals unless they are the burning type. As such, they are highly sought after by jewelrists and mechanics. [Mechanics because the burning gems are like unpowered plasma cutters. They're powerful.]

Solidified Flames are the bane of five-finger quirks' existences. Since they are technically fire, quirks like Overhaul, Zero Gravity and Decay don't work on it. [You can't deconstruct fire after all. Fire has no gravity, and they'res no physical matter to decay.]

Downsides

He's not fully immune - If someone hits him with fire that's stronger and hotter than the ones he can produce at the time then he'll still be burned, just slower. [This means that his Fire Immunity grows alongside his Heat and Flame Production, they are always equal to each other]

Fire is still hot - Thanks to his Fire Immunity fire doesn't effect him as much as heat does. He can still overheat, but it's slower than someone like Endeavor.

Water is a B**** - Izuku hates water. If used on his solid flames they'll be easier to break. It's his only way of releasing his capturee as well. If he's soaked and he uses his quirk at full power he'll get water burns as they evaporate, and if it's raining he just straight up can't use his quirk. So yeah, Izuku thinks water is a B****.

His Quirk makes him a target - Due to the value of his Solid Flames, people have attempted kidnappings on him before, and will probably continue to for as long as he weilds it.
