Dan Phantom A.K.A. Dark Danny is the evil full-ghost version of Danny Phantom, created by the fusion of the ghost-halves of the show's protagonist and the show's most powerful antagonist, Vlad Plasmius Unlike most of Danny Phantom's enemies who have, to some degree, a moral conscience, Dan possesses no such trait; he is pure evil and craves destruction and chaos.
