AgniFire Punch Wiki

Agni has his regeneration and is covered by the flames of Doma, which are never extinguished unless their target is completely ignited.

He also has a state called ''Fire Punch'' in which his regeneration is faster (I don't know how) and he enters a state of bloodlust where he will not regain consciousness until his face is completely regenerated.

Now,you have to kill him with a Random Power,but none absolute powers.
