Nebula

Nebula is the supervillain of the Marvel Comics universe, a blue-skinned alien warrior, Thanos' adopted daughter, and Gamora's half-sister. Nebula's early years are shrouded in mystery: there is no telling where she came from or who the heroine's real parents are. After Thanos killed her family, she grew up with Gamora and learned to be a warrior. Thanos often forced them to fight, and Nebula always lost. The long years of pain and torment have made Nebula a cruel and vengeful warrior. Most of all, Nebula hates her adoptive father. Therefore, her only meaning in life has been to retaliate against Thanos. In 2014, along with Ronan the Accuser, she betrayed her father, intending to destroy the planet Xandar and kill Thanos. She escaped from Xandar when the Guardians of the Galaxy successfully thwarted Ronan's attack. She was later captured by members of the Sovereign race when she tried to steal their powerful batteries. The Sovereigns gave her to the Guardians in exchange for their services to protect the batteries. When the Guardians visit the planet Ego, Nebula helps the Sovereigns capture Rocket and Groot. She is given a ship and goes in search of Gamora. After defeating her in battle, Nebula forgives her sister and helps her along with the Guardians in the battle against Ego. After the battle, she set out alone to exact revenge on Thanos. After unsuccessful attempts, she joins the Guardians of the Galaxy, the Avengers, and Dr. Strange to defeat Thanos. After Thanos' snap, Nebula was one of the survivors. She is highly intelligent and is a brilliant military strategist. On her wrists, she wears blasters that fire unknown powerful energy. Also uses a device that allows her to disguise her appearance. For some time possessed the Infinity Union, a combination of three devices that together can channel all forms of ambient energy into her. The character possessed the Infinity Gauntlet for some time, which gave her unlimited power and complete control over time and space.
