Those creeps and ghouls who chased Scooby-Doo and the gang around weren’t all that scary, because the adventures had to stay kid friendly, but what if some of horror’s most infamous slashers had co-starred in those Scooby Doo mysteries?
Scenes from the show might have looked an awful lot like these ghoulishly great artworks by illustrator Travis Falligrant, aka IB Trav, and the little viewers at home would've had nightmares for the rest of their lives.
Trav clearly wasn't impressed by the original Scooby-Doo baddies, so he raised the stakes by adding actual slashers like Freddy Krueger and Jason Voorhees to the classic cartoon mystery, careful to keep that signature Hanna-Barbera style in each character design.
It's a good thing real horror movie slashers weren't included in the original show, or the gang probably wouldn't have made it past the first season!
