This summer, the people behind The Avengers, will unleash a whole new set of superheroes on the world. 
But who exactly are, the Guardians of the Galaxy?

Like most heroes, the Guardians come from comic books. But what do they do? Exactly what it says on the tin - they guard the galaxy. And in this summer's blockbuster, they'll be taking on an intergalactic space jerk called Ronan. But these aren't the usual superbuff supermen. Take a look at the first official picture below, and meet the team...

Gamora (Zoe Saldana)
Saldana plays a green skinned badass, who has chosen to follow the good guys after turning her back on her adoptive father, and Marvel supervillain, Thanos. 

Peter Quill (Chris Pratt)
Parks & Recreation's Pratt had to beef up to play Quill, the only human member of the team. But he's still got plenty of humour, and a spiffy jacket, too.

Rocket Racoon (Bradley Cooper)
It gets weird now. Oscar nominated Cooper will voice this genetically engineered mammal that also happens to be an expert marksman. It works, trusts us.

Drax the Destroyer (Dave Bautista)
Former WWE superstar, Bautista, is the perfect fit (literally) for this pumped up warrior, who's hell bent on avenging the death of his family.

Groot (Vin Diesel)
This guy's a big tree! No, seriously. Groot's a hyper intelligent plant with the ability to control other trees. He's a space Ent, basically, and Vin Diesel's doing the voice.

Guardians of the Galaxy is released on August 1st
