Vladimir "Vlad" Masters, also known as Vlad Plasmius, is the main antagonist of Danny Phantom. A rich, debonair billionaire, Vlad is a powerful half-ghost whose twenty years of experience constantly one-up Danny's own ghostly abilities. He vows to destroy Danny's father, Jack for "stealing" Maddie from him, and also for giving him his ghost powers which in the process put him into a hospital room for seven years. He is a devious man whose exterior charm hides a manipulative interior. He is sneaky and often uses the people he knows as pawns to get what he wants.
