You can call the idea of a raccoon teaming up with a tree "unlikely" -- or just plain crazy -- but it's the essential pairing in Guardians of the Galaxy, Marvel's new team-up movie. Rocket Raccoon (voiced by Bradley Cooper) and Groot, a sentient tree (voiced by Vin Diesel) have worked together for years and always have each other's back. They form the backbone of the so-called "guardians," who work together for the betterment of mankind.
In the world of horror movies, such pairings are fraught with danger. After all, who wants to team up with a monster who might (literally) eat you up, or is more likely to kill you than to ask about your family? Perhaps that's why these unlikely horror team-ups are so memorable.
Half-mortal and half-vampire, Blade (Wesley Snipes) has an experienced partner in Abraham Whistler (Kris Kristofferson). After coming to the aid of Dr. Karen Jenson (N'Bushe Wright), who has been bitten by a vampire, Blade teams up with her, but how long can their partnership last against the likes of the villainous Deacon Frost (Stephen Dorff)?
Vampires and werewolves are engaged in an epic war, so the prospect of vampire Selene (Kate Beckinsale) pairing with werewolf Michael (Scott Speedman) sounds like the unlikeliest team-up of supernatural creatures possible.
Originating in the mind of comic book artist Mike Mignola, the heroic demon Hellboy (Ron Perlman) makes for the most unlikely of partners for fellow members of the Bureau for Paranormal Research and Defense.
The legendary Warrior Priest (Paul Bettany) doesn't really need any partners, yet finds himself teamed with a vengeful sheriff (Cam Gigandet), as well as a crusading former Warrior Priestess (Maggie Q), in his mission to rescue his niece (Lilly Collins) from vampires.
The Monster Squad (1987)
Our favorite, and most unlikely, horror movie team-up originated in the minds of co-writers Shane Black and Fred Dekker, who dreamed up a scenario in which monster-minded kids end up saving the world. Dekker directed, and it's a delirious and delightfully bent fantasy come to life, as the kids must fend off the evil intentions of Dracula and his posse of classic monsters, with only Frankenstein's creature on their side.
