"Gamora is a green-skinned assassin known throughout the universe as a fearless warrior and the foster child of big bad Thanos. Sci-fi veteran Zoe Saldana steps into the character's boots for the film and says she learned more about the character from her 11-year-old comic-reading nephew than anyone else. “He goes, 'Who do you think Gamora is?'” Saldana recalled. "And I said, 'She’s a warrior.' He goes, 'Yeah, but not only is she a warrior, she’s an assassin and she’s very lethal but what saves her is the same thing that can doom her. She has a sense of righteousness. She’s a very righteous individual… and that was coming from like an 11-year-old boy and I was just like that’s it. That's gonna be like the overall like mojo of Gamora is her sense of always wanting to do the right thing, which is why she compels, she’s trying to ask the Guardians not to sell their souls for money, because if it means that a lot of people will lose their lives then it’s not really worth it, because she’s sort of like the one that kind of starts going in that direction and then everybody else kind of follows too, which is what I like the most about this movie is that we’re all starting like inmates."
