Vampires, werewolves, maenads, shape-shifters, weird panther-type creatures and now witches — HBO's True Blood harbors all manner of supernatural beings in its menagerie of characters.

The great thing is that each of these otherworldly characters brings with them enough crazy drama to fill an entire season of Jersey Shore, so there's a lot to look forward to in Season 4 of the show, which revs up on HBO this Sunday. From mainstays like inexplicably-well-adjusted-considering-her-environment waitress Sookie Stackhouse (played by Anna Paquin) and mildly bipolar vampire Bill Compton (Stephen Moyer) to new bloods like Jesus (Kevin Alejandro), a whole lot of folks are in the mix.
