Toyah Todoroki

Temperature: His flames reach 2000°C and higher (in canon, enough to instantly incinerate the body itself). Here, he can maintain this temperature indefinitely.
Skin: His skin possesses an innate heat resistance comparable to future fireproof materials. This isn't just pain tolerance—fire feels like a warm breeze to him.
Stance: In battle, he would stand within his own flames. Imagine the epicenter of an explosion that never dies down, standing calmly, arms crossed, looking at you through a blue glow.

If the body is not in pain and is not destroyed, terrifying possibilities open up:

Plasma Armor: He surrounds his body with a layer of plasma, right up to his skin. Anyone who tries to strike him in close combat (like Endeavor with his fist) will simply lose a limb upon impact. He becomes a "hedgehog," impossible to touch.
Full Throttle: In canon, he used fire for short bursts. Here, he's a fighter. Constant jet thrust from his feet and shoulder blades without fear of ripping his legs off. Speed ​​and maneuverability on par with professional speed heroes.
Blue Sun: An attack that mimics a supernova. He simply begins concentrating flames in a single spot in front of him, without dissipating heat from his body. The temperature rises to the limit, until the very air and the asphalt beneath his feet begin to melt. No one within a 50-meter radius will survive.

Appearance
Face and Skin: Smooth, clear, very fair porcelain skin, just like his mother, Rei's. No burns, tightness, or purple scars. His features are delicate and aristocratic, with well-defined cheekbones. He has a handsome, even doll-like face that could belong to an idol, but there's something dark lurking in his gaze.
Hair: Pure white, like snow, or with a subtle cool blue tint. Thick, slightly wavy, and unruly, it falls naturally into his eyes, giving him a more mysterious and less aggressive look. The lack of black hair color brightens his look, but his eyes still give away his natural nature.
Eyes: Angie's eyes are a vibrant, pure turquoise. They're perfectly visible without the scars. They have the same long lower lashes, but the gaze is open. There's no manic obsession with revenge, but there's a deep, frightening emptiness or all-consuming apathy.
Build: The same tall, wiry, lean body, but slightly muscular. But the skin is clear everywhere. In this world, he doesn't need to hide his body under baggy clothes. He moves with the lazy grace of a natural genius, not the twitchy nervousness of a psychopath.
His quirk is blue fire.
