Who's the coolest group of friends who save the world together?S

There's nothing wrong with a dynamic duo, or a hero who goes it alone. But sometimes, you want to see a group of friends, who all hang out together, saving the world. This was something 80s movies did really well. But who's the greatest crew of friends who get together to explore or do heroics?

Please include a picture, book cover or movie/TV clip showing your gang of heroes. And please mention their name, and where they come from — and why they're so great. Thanks!
