It's the "Deadliest Women in the Galaxy", Thano's adopted daughter, Gamora.
Kinda hard to believe that was three years before 1978's "Superman" hit the screen isn’t it?
Gamora is the "Deadliest Woman in the Universe". She is a trained assassin plus she has your standard heightened speed, strength, agility, durability and of course an accelerated healing factor.
I mean..you just have to have all those things right?
Though seriously...this woman is bad. She can go toe to toe with the "Big Boys" and has taken out entire armies by herself.
Gamora has also been the girlfriend of Adam Warlock and Nova.
The more eagle eyed among you may have spotted Warlock's cocoon in the Collector's ship at the end of Thor: The Dark World.
So....he may not be far behind in the MCU.
