Gamora and Mantis first met on Berhert, where Ego had found his son after twenty-six years.

Gamora on Mantis
Gamora did not immediately trust Mantis, as she believed the latter of the two was hiding something after overhearing Mantis nearly warning Drax what Ego was planning. Despite being suspicious of Mantis, Gamora remained polite to Mantis, such as kindly asking where their quarters were at.

Gamora later attacks Mantis after seeing the skeletons of Ego's children, but this was only because she believed Peter was in mortal danger.

Mantis on Gamora
Mantis came aware of Peter Quill's feelings for Gamora, for which she calls a "romantic, sexual love". During the trip back to Ego's Planet, Mantis attempted to learn Gamora's true feelings, but the young woman threatened to give Mantis a broken jaw if she touched her. Mantis had told Gamora that Drax told her many things, like her being ugly.

After Gamora found the dead bodies of Ego's children, she immediately threatened Mantis by forcing her into a chokehold, demanding who the bodies in the cave wer. The threats made Mantis terrified and she could sense Gamora was sared and enhanced her face and released her from her chokehold
