What The Avengers: Infinity War Cast Look Like In The Comics

In the Comics:

A fierce and fearsome space pirate, Nebula was the one to ravage Xandar and parts of the Skrull empire, claiming to be Thanos' granddaughter. Thanos held her in great disdain, using the Infinity Gauntlet to turn her into a living corpse to please Lady Death.

At one time, when Thanos left his physical body in his throne, Nebula was able to steal the Infinity Gauntlet away, and Thanos was forced to help other heroes in thwarting her omnipotence.

In the Film:

One of Thanos's adoptive daughters, Nebula was broken down and replaced with parts, reviled where her sister Gamora was loved. She attempts to murder Thanos sometime before the events of Infinity War, but Thanos captures and tortures her, using her as leverage to force Gamora to lead him to the Soul Stone.

She's able to escape and meet back up with the Guardians, and is the last woman standing alongside Tony Stark when the entire team sans Rocket are disintegrated.

She's played by Scottish actress Karen Gillan, her appearance more mechanical than her comics counterpart, who has a full ensemble of tights and long, black hair, which film Nebula lacks, as she's shaved bald. They both, however, share her blue skin.
