Gamora/Relationships

Thanos
"He's not my father."

- Gamora to Quill

Thanos mistreated Gamora and killed her own parents and her entire species right in front of Gamora. He turned her into a weapon, and made sure she became is personal assassin. Gamora hates her adoptive father and ends up betraying him in the end. According to Nebula, Thanos always favored Gamora over his other children. He even made Gamora turn against Nebula (who was poorly mistreated because every time Gamora prevailed, Nebula ended up being literally ripped apart). She willingly betrays him for the sake of saving everyone in the galaxy.

She is later shocked that Drax wishes to kill her "father", but ends up continuing.

Thanos and Gamora's relationship serves a foil to Yondu's and Peter's familial relationship.

Nebula
"You will always be my sister"

- Gamora to Nebula before they depart

Gamora's and Nebula's relationship can be compared to Loki's and Thor's, and can also be compared to Regina and Zelena.

Bilbo Baggins
Gamora first met Bilbo when they are on Xandar, and almost tried to kill him. However, shortly after Peter saved Gamora, she instantly takes a liking to Bilbo, and excludes him from being "part of the biggest idiots in the galaxy".
