There are times when stopping the bad guys is best achieved by heroes who are no strangers to being a little bit bad themselves. In Marvel’s Guardians of the Galaxy, Peter Quill (Chris Pratt) is one of those heroes, and he’s joined by deadly assassin Gamora (Zoe Saldana), vengeful maniac Drax (Dave Bautista), walking tree creature Groot (Vin Diesel) and a genetically-engineered raccoon called Rocket (Bradley Cooper).

When it comes to unlikely heroes, this ragtag group of thugs and criminals are about as unlikely as it comes, so one of the tasks laid out for co-writer and director James Gunn is to explain how a group of people who are usually only concerned about themselves somehow get drawn into protecting the entire galaxy.

Luckily, guarding the galaxy just so happens to align with the Guardians’ personal interests. In the comics, Gamora has a lot of history with both arch-villain Thanos and with space pirate Nebula (Karen Gillan), while Drax is seeking to exact justice for the death of his family. In the latest TV trailer for Guardians of the Galaxy, Peter Quill’s explanation for why he’s so determined to defend the galaxy comes down to something very simple: he’s one of the idiots who lives in it.

The TV trailer also features another classic song for the nostalgia-lovers out there: The Runaways’ “Cherry Bomb”. As with the previous soundtrack choices like “Hooked on a Feeling” and “Spirit in the Sky”, this song doesn’t sound like it should work in the context of a trailer for a sci-fi movie but somehow ends up fitting perfectly with the tone. Rocket is the fox space raccoon you’ve been waiting for.

There are a few tidbits of new footage mixed in with the old, including another line from Peter “what a bunch of a-holes” Serafinowicz, who plays a Nova Corps officer. In fact, the impression that this trailer gives is that the Nova Corps will be the outer space equivalent of S.H.I.E.L.D. in The Avengers, though keeping the Guardians under control might prove trickier than watching over Earth’s Mightiest Heroes.

Guardians of the Galaxy is out in theaters on August 1, 2014.
