Rogles

Emperor of The Dark World. He wants to invade all realms with his monster horde and crush all that stands in his way. Rogles has always hated the Valis sword, so like the cartoonish supervillain he is, he made a "dark" version of it that only a certain futanari can wield.

Rogles is also a powerful sorcerer. His magic is so strong and so evil that it can make girls grow penises when he rapes them.
