Gamora and Nebula are adoptive sisters and adopted daughters of Thanos. Both of them had a rivalry since childhood after Gamora always bested Nebula in battle. For years, Gamora never understood her sister's desire to always be better than her, until Nebula pointed out that all she wanted was a sister. Both sisters finally forgave each other, but Nebula didn't stay to become a Guardian and only left to kill Thanos.
Nebula is played by Karen Gillan while Gamora is portrayed by Zoe Saldana.
Trivia[]
- It is most likely that Nebula is younger than Gamora because of her younger sibling-like behaviour.
- Zoe Saldana has said the relationship between Gamora and Nebula is her favorite aspect of Guardians of the Galaxy, and hits close to home for her, having sisters of her own.
