In 'Big Hero 6,' a young inventor, Hiro, and his vinyl robot, Baymax, must recruit some pals to save the day from the bad guys. These unlikely heroes aren't the first to join forces and fight for the side of good. This gallery is devoted to films that feature more suprising team-ups on the big screen. 

Instead of saving the world, these outcast teens -- and their giant friend, Sloth --- save the next best thing: their homes. When it comes to outsmarting a dangerous-but-dim crime family or solving deadly booby traps, you're gonna want the Goonies on the case. 

Marvel's latest big-screen hit arguably features the most unlikely team of heroes ever assembled. It's good to know that, when the universe needs saving, we can always count on a sentient tree and a snarky raccoon with an itchy trigger finger. You're welcome, galaxy. 

The cast of the war movie-within-the-movie 'Tropic Thunder' includes: a fading action movie hero, the star of 'The Fatties: Fart II,' a five-time Oscar-winning Method actor, a timid Canadian and a rapper. All of them have their issues, which they hilariously put aside to thwart machine-gun wielding villains to save the day in this hit comedy. 

When Dracula and his band of scary creatures threaten their small town, these young monster experts must lace up their Keds and sharpen their wooden stakes to stop them. Along the way, they settle the age-old debate about whether or not the Wolfman has "nards."

Not all heroes need to have cool costumes or save the world.

Welcome to Ouch Town, White: population, you, bro!

Not exactly the best of friends in high school, uber-jock Jenko (Channing Tatum) and brace-faced nerd Schmidt (Jonah Hill) must team up to infiltrate and take down a high school drug ring. These unlikely cops somehow manage to get the job done. 

When zombies infect England, who ya gonna call? Shaun (Simon Pegg) and his quirky group of friends. All they need are clever banter, a few pints and a cricket bat. 

When the Apocalypse strikes Hollywood's backyard, the last people you'd expect to save us from all things brimstone are Seth Rogen, James Franco, Jonah Hill and their movie pals. Their efforts are surprisingly, and hilariously, successful. 

If only more history-class grades could be saved with the help of Bill, Ted and their time-traveling phone booth. These guys are the high school equivalent of Doctor Who, and that's far from "bogus." 

Three disgraced scientists and Winston are all that stand between us and a 30-foot marshmallow man. When it comes to saving the world, these four are are the only ones we'd trust to do it while wearing unlicensed nuclear accelerators on their backs.
