Mothraya is a mid boss from Rosenkreuzstilette Freudenstachel.

Mothraya is a giant moth that attacks by shooting a projectile and collapsing the floor over a spike trap. After shooting its projectile, it will teleport away, giving less time to hit it. Mothraya can be killed quickly by one usage of the Freudenzwinger. It is based on the Mega Man 4 boss of the same name.

It is fought in the Phalanx Cathedral Ruins (Eifer's stage).
