The Story of Tony Stark/Iron Man (Marvel Cinematic Universe)

Infinity War: Convening at the New York Sanctum

After meeting Doctor Strange and reuniting with Bruce Banner, Tony was taken inside the New York Sanctum. He was informed by Wong, who explained the history of the Infinity Stones; Strange named all of the stones that were known such as the Space, Reality, Power, Soul, Mind, and Time. Stark inquires the enemy's name and was informed by Banner that it was Thanos, explaining that he has acquired the Power and Space stones; making him the most powerful being in the universe.

Having learned that Thanos was the one who pulled the strings behind Loki and the Chitauri Invasion, Stark realizes that he was the one who was really responsible for his fear and anxiety in the ensuing years since the Battle of New York. Leaning and stretching against the Cauldron of the Cosmos, Stark remarks on Strange's use of language, getting hit by the Cloak of Levitation, much of his allowance. Stark suggested disposing the Time Stone, but Strange and Wong informed him they were sworn to protect it.

As Thanos had two stones and the other two were not on Earth, the best move would be to protect Vision, who had the Mind Stone embedded in his head; however, Vision had disappeared two weeks earlier. Only the fugitive Captain America could possibly find him. Banner insisted that Stark call Rogers, only for Stark to explain to Banner that him and Rogers had fallen out, and that they were not on speaking terms. Banner would convinced Stark to call Rogers by telling him that Thanos had killed their teammate Thor. However, before Stark could place the call, they were interrupted by the sound of agitation in the streets and debris flying through the air.
