Carina

Carina is a minor character in Guardians of the Galaxy and briefly appears in Thor: The Dark World. She is the servant of the Collector, but was poorly treated by him and wishes to escape his evil clutches.

She was portrayed by Ophelia Lovibond.

Before GOTG
Carina discussed the repercussions of hiring Gamora for the Infinity Stone to her master, but the Collector doesn't care.

Guardians of the Galaxy
Carina retrieves Gamora and her newly formed band later known as the "Guardians of the Galaxy" and introduces them to the Collector. She later learned the history of the Infinity Stone and wished to wield it. Wishing to no longer being in the Collector's servitude, Carina attempts to take the Infinity Stone and use its power, but to her shock it just literally rips her apart.

Trivia

 * Carina is based on Carina Tivan, the daughter of the Collector. However, instead of being his daughter, Carina was made his servant.
