Gamora and Nebula's Siblings

Gamora's and Nebula's siblings 'were characters mentioned in Guardians of the Galaxy.

Presumably like Nebula and Gamora, they were taken from their biological families after Thanos killed their biological parents and raised them as children of his own. However, he treated them like weapons and possessions rather than children.

Nebula
According to Nebula, she didn't like any of her siblings and claimed she hated Gamora the least.
