Graf Michael Zeppelin is the leader of RKS and the biological father of Iris Zeppelin. Thought to be the main antagonist of the game, that title is passed on to Iris after he is defeated.
Zeppelin is considered the Dracula of Rosenkreuzstilette because he is based on the Dracula (castlevania) in Castlevania (series) and can also transform into a large demon just like him.
