POKÉDEX ENTRY:

When a Mightyena is driven from its pack for being too weak, it is overcome with intense rage and evolves. It then hunts down its former packmates one by one.

Frightyena is exclusively solitary. The intense fury from past neglect gives its claws phantasmal energy and life-draining qualities. It consumes both the flesh and souls of prey.

SIGNATURE MOVE: PHANTASMAL CLAW
TYPE: GHOST

Sensing the life force of prey, the user closes in and strikes savagely. This move will land without fail.
