13. Hellboy (2004)
The Monster: Well, Hellboy himself, though he’s not a monster in the traditional sense of the word. Sure he’s part demon (and looks it), but he also defends mankind from the real nasties.
The Movie: Oh look, Guillermo del Toro again! The monster-loving director helmed this film version of the comic book, which follows the arrival of Hellboy (Ron Perlman) on Earth and his subsequent adventures as a member of the Bureau of Paranormal Research and Defense.
Coolest Detail: Fortuitously, Ron Perlman turned out to be left-handed, which meant that Hellboy’s Right Hand of Doom (the big stone one) could remain unchanged in the film.
