This is a Teen Titans tale with a somewhat "Guardians of the Galaxy" kind of theme. The Teen Titans are alien outlaws, and have to team up to save the universe.
Robin is an intergalactic bounty hunter from Earth, who teams up with the outlaws to take down Trigon who is going to destroy the universe with an artifact.
Starfire is famous for destruction of public property. She's from Tamarran.
Beast Boy is a mugger from a planet called N'Vorkel, who attacks thieves for the loot they have.
Cyborg is an assassin from a planet called Mechmanier.
Raven is a thief from a planet called Azarath, who steals anything she can get her hands on and sells the loot. She's also the one who sets the story in motion by stealing an artifact from N'Vorkel, which Trigon is trying to obtain.
There's a lot of BBRae and RobStar, as well as some mention of CyBee.
