Nebula hates pretty much everyone in the galaxy. Especially her sister, Gamora. And it's fair to say the feeling's mutual. It's hardly surprising. Taken from their homes as childrens, Thanos surgically modified the girls training them to become weapons, forcing them to compete against each other over and over . . . until they felt nothing. Gamora always had to win. And Thanos always punished the loser painfully. So the way Nebula sees it, Gamora is to blame for everything that's wrong in her life. And when she ends up handcuffed, hungry and held captive on the Milano by Gamora, a talking roden, a tattooed man, a humanoid plant and a scruffy-looking Terran going by the name Star-Lord . . . Nebula wants revenge.
