Every MCU Villain Ranked Weakest To Strongest

Before she became a leading figure in the Avengers and a member of the Guardians of the Galaxy, Nebula was wholeheartedly loyal to her father, Thanos, and the Mad Titan's quest for the Infinity Stones. Trained to fight by her father, her body was altered with robotic attachments every time she failed him.

Over time, Nebula grew into one of the galaxy's most fearsome warriors, able to take one hell of a beating from enemies much more imposing than her. She also grew to beat her always-stronger sister Gamora in combat, and made an almost successful attempt to kill Thanos after finding herself fighting with the Guardians.

She wasn't a villain for long, but with her superior fighting skills and various cybernetic enhancements, she was a menacing adversary all the same.
