Former villain turned Avenger, Nebula is the adopted daughter of Thanos. While serving as Ronan the Accuser’s right-hand aid, Nebula was a deadly assassin who often quarreled with her adopted sister, Gamora. After years of attempting to assassinate Thanos, Nebula joined forces with the Guardians of the Galaxy, Spider-Man, Dr. Strange and Iron Man during the Battle of Titan. If there’s anybody who knows how Thanos thinks and operates, it’s Nebula. That information could prove to pay dividends.
