Abilities:

Latent Quirk: Psycho Flames - An extremely powerful and versatile quirk that reflects the emotional and mental state of the user, manifests as green flames. They are normally cold. Flames attack others' mental state, invoking fear and dread instead of physical pain, a reflection of the user wanting solitude, feeling miserable or wanting to intimidate others. The flames become searing hot when the user is furious or focusing on creating heat.

Cold flames stay alight until the user snuffs them out or is a distance away from them. Hot flames are more resilient than other fires, but can be put out. They spread over any surface, even things that don't conduct heat.

Pyrokinesis - user can control his own flames as well as others. Fires from another person's quirk are more difficult to control.

Heat Sensing - User can detect a person's presence and read their emotional state by the heat they emit. Both are much easier with people with heat quirks.

Thermal Vision - Alternate set of vision that picks up heat signatures.

Barrier (Weak against sharp objects)

Telekinetic Negation

Flight

Flame Creation

High Endurance

Above average physical strength

Razor-sharp mind (multi-tasking, studying and retaining knowledge surpasses even Momo Yaoyorozu)
Speedwriter and speedreader

Unrivaled cooking skills (just because)

Well-versed in first-aid (especially on himself)

Grows stronger the longer battles progress as his flames grow and spread

Other Techniques/Ultimate Moves

Flashfire Fist (Jet Burn, Hell Spider, Prominence Burn) [Learned from watching Endeavor]

"Pyro-voyance" (Can see and hear through the green flames he controls, can also be used as extra appendages)

Paralysis (Covers opponent in flames to control their bodily movements like strings on a puppet)

Faux Fierce Wings [Mimicking Hawks] (Manifests flaming wings on his back for faster flight and can pull them off as broad swords)

Green Explosions (AP-Shot variants, Stun Grenade, Howitzer Impact) [(Initially) Mimicry of Bakugo, vexing but useful]

Green Magma - (Melts down surrounding materials such as stone, concrete, solid earth and road tar into magma which can be molded into devastating meteors of unparalleled condensed firepower)

Hell Splitter - (Forms a blade of fire on his arm that slices through anything with its sharp edge and searing heat. Can discharge slash attacks)

Final Shine (Final Flash stance) [Vegeta's gonna sue]

Green Hell (Envelope the surrounding area in raging fire. User can detect movements within the flames, making sneak attacks impossible. The flames burn hotter and brighter where the user is)

Drawbacks

Hot Fire - Producing heat causes body temperature to rise. Solution - Switch to cold flames or control flames he already lit.

Cold Fire - No physical recoil whatsoever.

Pyrokinesis & Flame Creation - Controlling large amounts of fire strains the mind, causing moderate headaches.

Producing Fire - Drains the stamina. Solution - Absorb lingering green fire to regain stamina.
