Furnifraß

Black: It breathes through a hole in its tail while it burns with an internal fire. Durant is its prey.

White +2: Using their very hot, flame-covered tongues, they burn through Durant’s steel bodies and consume their insides.

Black 2 +3: It draws in air through its tail, transforms it into fire, and uses it like a tongue. It melts Durant and eats them.

Sword: There’s a hole in its tail that allows it to draw in the air it needs to keep its fire burning. If the hole gets blocked, this Pokémon will fall ill.

Shield: A flame serves as its tongue, melting through the hard shell of Durant so that Heatmor can devour their insides.
