Bloodlines: The Dracula Family Tree

When Hellboy, Liz Sherman, and Abe Sapien are assigned to investigate the ghost-infested mansion of a publicity-hound billionaire, they uncover a plot to resurrect a beautiful yet monstrous vampire from Professor Bruttenholm’s past. But before they can stop her bloodbath, Hellboy will have to battle harpies, hellhounds, a giant werewolf, and even the ferocious goddess Hecate herself.

Scooby, Shaggy and Scrappy are on their way to Miss Grimwood's Finishing School for Girls, where they've been hired as gym teachers. Once there, however, they find that not only is it actually an all-girl school of famous monsters' daughters but there's a villainess out to enslave the girls.
