Nebula appears to be the photo-negative of her sister: cruel, evil, and considered by men as strong as the Ravagers as the galaxy's biggest sadist. Despite turning against Thanos, she was still a criminal whose primary focus was what supported her in the moment (not unlike Loki). However, she has become more mellow and heroic in recent years, showing a selfless and heroic side as she willingly participates in the Infinity War. Nebula is intelligent, but she appears not to be very good at creating strategies. For instance, she deserted Ronan when he was (currently) her only hope against Thanos, and she damaged her own ship attempting to shoot down Gamora. Prior to the Infinity War, Nebula appeared to be very disloyal, as she ultimately betrays everyone and works for her own ends. Her exploits after the Battle of Xandar have been a journey of renewal for her as she begins to determine her own ideas of good and evil.
