The Minion Plague

Plague is a half man half demon creature.
The only more like a human to him is his head, at least half of his face.
But from neck down his body is covered with different kind of plague insects.
He is the very first minion of Satan.
He only cares for himself and his lord, a manipulative and tricky minion, that’s why other minions often argue with him.
He can also morph into a plague of different kind of insects.
