I personally love Nebula for multiple reasons but mainly because I can really relate to her. Her and Gamora have had a really tough life and they both try to survive in their own way; for instance Nebula trys so hard for her father's love and approval but is still not his favorite which he tells her all the time saying that he just wants to make her "better". She has so many layers and I can't wait for Marvel to show us more about her.
