Thanos is a minor antagonist of The Avengers, a minor antagonist of Guardians of the Galaxy and the main antagonist of The Avengers: Infinity War - Part 1 and 2.

The Avengers

At some point during his quest, Thanos discovered that the Tesseract, the Space Stone, was on Earth, and allied himself with the exiled Loki providing him with the Chitauri, who would help him conquer the planet in exchange for the Tesseract. Once Loki had arrived on Earth, he succeeded in acquiring the Tesseract, but as he was preparing for his invasion, Thanos contacted him. Through his intermediary, The Other, Thanos threatened the Asgardian god of mischief, saying that if he failed in delivering the Tesseract, Thanos would force him to endure a new kind of suffering.

After Loki was defeated, the Other reported to his master that the Earth's inhabitants were not as weak as they were thought to be. He also declared that challenging the heroes would be to court Death. To this, Thanos simply smiled.

Guardians of the Galaxy

Thanos destroyed Gamora's planet and her kind, but took her under his care as an adoptive daughter and trained her as an assassin along with Nebula. Ronan the Accuser made a deal with Thanos - to retrieve a mysterious artifact, and in exchange Xandar will finally be eradicated. However Ronan breaks the deal, thinking that with the Infinity Stone he no longer needs Thanos' help to wipe Xandar out. Both Gamora and Nebula wanted to be free from Thanos, the former betrayed him by joining Star Lord and the latter swore allegiance to Ronan and promised that she'll destroy 1000 worlds for Ronan for freeing her from Thanos.
