The character played a role in the 2007 crossover storyline "Annihilation: Conquest", becoming a member of the titular team in its spin-off comic, Guardians of the Galaxy, before becoming the supervillain Requiem in the 2018 crossover storylines "Infinity Countdown" and "Infinity Wars".

Gamora was raised and trained by Thanos to assassinate the Magus, the evil, future version of Adam Warlock.

Thanos showed her little kindness during her childhood, but Gamora was very loyal to the man who promised her the opportunity to avenge the death of her family.

Thanos found her half dead, and in turn, murdered all of her assailants and restored her to health, cybernetically enhancing her to superhuman levels.

As an adult, Gamora was sent as an assassin against the Universal Church of Truth, quickly becoming feared by its agents, the Black Knights.

She exacted revenge for the genocide of her race by killing every member of the church involved before the event occurred.

Together with Warlock, Pip the Troll and Thanos, Gamora fought to escape the Black Knights of the Universal Church of Truth and Magus's Death Squad.

Other beings who had been absorbed by the Soul Gem, such as Kray-Tor and Autolycus, also lived in peace with former enemies.

Gamora met the Silver Surfer when he traveled to Soul World, and also battled Drax the Destroyer.

Gamora and Pip persuaded Doctor Strange to help them find and stop Warlock, who was going mad with power.

Gamora received the Time Gem, but was incapable of consciously using it, though it did give her sporadic precognitive dreams and visions.

[19] Gamora later reappears in the pages of Ronan, having left the company of Adam Warlock and settled on the world Godthab Omega as leader of a group of female warriors called The Graces, where her mind has been altered by Glorian.

She is intent on re-establishing her reputation as the deadliest woman in the universe and now wields the Godslayer sword.

She joins the United Front, using her skills to launch quick counterattacks against the Annihilation Wave.

[22] During the Phalanx's invasion of the Kree home-world following the Annihilation War, Gamora is assimilated as a "select" of the hive mind.

[31] During the Original Sin storyline, Gamora was seen with Moon Knight and Winter Soldier's group, investigating the murder of Uatu the Watcher.

[32] Later, Gamora was confronted in her dreams by an elderly version of herself who turned out to be a part of her which had remained trapped in the Soul Stone after she left its internal paradise.

Ultimately, Gamora is defeated and sent to another planet alongside a resurrected Magus, while the merged universe is preserved as a pocket dimension inside the Soul Gem.

[36][37][38][39] When it was learned from Thanos' will that he plans to resurrect himself by uploading his consciousness into an unrevealed being, many assumed it was Gamora.

[40] As the Dark Guardians were about to kill Gamora, they were attacked by Hela and the Black Order who planned to resurrect Thanos.

[42] Gamora received treatments from Thanos that enhanced her speed, strength, agility, and durability to rival Adam Warlock's (to better slay the Magus, his evil, future self).

She uses a wide variety of weaponry, most notably a dagger whose unknown properties made it capable of slaying even beings of such immense power as Thanos and the Magus.

In the pages of Infinity Watch, it is revealed that Gamora had been cybernetically enhanced to have superhuman strength, speed, and a rapid-healing ability.

She has learned to paralyze or kill opponents using vital-point strikes directed at certain nerve clusters.

While she possessed the Time Gem, Gamora was prone to precognitive dreams and visions, though she had no conscious control over them.

[volume & issue needed] Later, despite no longer possessing the gem, she was claimed to retain some measure of this capability at the time of the Phalanx conquest.

[66][67][68] Additionally, Ariana Greenblatt portrays a young Gamora in Infinity War[69] while Cynthia McWilliams voices an alternate timeline variant in the Disney+ animated series What If...?.
