Vampires aren't supposed to age ... right? That fact has been a mainstay in every iteration of the bloodsucker mythology, even in 'True Blood.' Though, the same cannot be said for the actual cast members.

HBO has done its best to portray Bill Compton (Stephen Moyer), Eric Northman (Alexander Skarsgard) and their vampire buddies in the same immortal state from season to season. Now that 'True Blood' debuted its first episode of season 6, however, it seems more apparent than ever that even makeup can't hide the inevitable aging of the cast.

Check out the characters of 'True Blood' back in the days of season 1, and see how different they look now in season 6!
