Sacrifice of Gamora

"In order to take the stone, you must lose that which you love. A soul for a soul."

- Stonekeeper

The Sacrifice of Gamora was the result of an attempt by Thanos to obtain the Soul Stone.

Background
"I need to ask a favor." "Yeah sure." "One way or another, the path that we’re on, leads to Thanos." "Which are what the grenades are for." "If things go wrong, if Thanos gets me, I want you to promise me, you’ll kill me." "Why does someone always have to die in this scenario?"

- Star-Lord and Gamora To be added

Sacrifice
"All my life I dreamed of a day, a moment, when you got what you deserved. And I was always so disappointed. But now, you kill and torture and you call it mercy. The universe has judged you. You asked it for a prize and it told you no. You failed. And do you wanna know why? Because you love nothing. No one." "No." "Really, tears?" "They are not for him." "No. This isn't love." "I ignored my destiny once, I can not do that again. Even for you. I'm sorry, little one." "No!"

- Gamora, Thanos and Red Skull When they arrived on Vormir, the Stonekeeper lead Thanos and Gamora to the location of the Soul Stone. The Stonekeeper informed them that the in order to obtain the stone, the possessor must make a sacrifice of the thing they love. To Gamora's amusement, she laughed at her adopted father, claiming that he loves nothing and this is the universes way of punishing him. However, Thanos was in fact deeply saddened as Gamora was the only thing he loved and turned around to reveal tears. Gamora then realized that Thanos loved her in horror. Although she seemed genuinely surprised and almost happy about it, Gamora quickly tried to kill herself, but is thwarted by Thanos's use of the Reality Stone. Thanos then grabbed her and dragged her towards the edge of the cliff, despite her screams, and threw her off, ultimately killing her. Once she had died from impact, Thanos was granted with the Soul Stone and headed to Titan meet up with his Black Order.

Aftermath
"He mourns." "What does this monster have to mourn?" "Gamora. He took her to Vormir. He came back with the Soul Stone, and she didn't." "Okay, Quill, you gotta cool it right now, you understand? Don't, don't, don't engage, we almost got this off!" "Tell me she's lying. Asshole! Tell me you didn't do it." "I had to." "No, you didn't. No, you didn't."

- Mantis, Drax the Destroyer, Nebula, Iron Man, Star-Lord and Thanos Thanos, now equipped with four Infinity Stones, arrived on Titan where he was ambushed by the Avengers, the Guardians of the Galaxy and Doctor Strange. The heroes were able to subdue Thanos, with Mantis using her powers to dig deep into his emotions psyche. They were about to remove the Infinity Gauntlet until Star-Lord began to ask about Gamora. Mantis stated that Thanos is mourning, something which shocked all of them to realize that he actually has people he loves.

Upon hearing this, Nebula then realized that Thanos must have reluctantly killed her, so that he can become worthy to possess the Soul Stone, and because he actually loved her as his daughter, the action has emotionally scarred him. Star-Lord then became furious and lashed out at Thanos, who was actually grieving about killing his daughter, causing Thanos to become determined to not let her death be in vain, breaking free and defeating the heroes. When he finally collected all the stones, he snapped his fingers and ripped out half of the universes population. Thanos found himself in limbo, where he met a young Gamora and told her he finally completed his mission. When she asked what it cost, he solemnly replied, "Everything", as Gamora was the only thing he genuinely cared for. Gamora sadly smiled in process before Thanos returned to reality.
