Fire God Slayer Magic incorporates the element of fire into the user's body, allowing them to produce black flames from any part of their body, which are mostly used as a means for offense. The user is also able to consume external sources of fire in order to replenish their strength and rid themselves of fatigue, thereby making them immune to fire-based attacks, much like a Fire Dragon Slayer. However, a Fire God Slayer is able to eat the flames produced by a Fire Dragon Slayer, with the reverse being normally impossible for said Dragon Slayer, except under special circumstances. In addition, God Flames do not burn. Rather, they have been described to be more like halberds that destroy everything in their path.
