After the Civil War in Team 3, Tony's physical condition deteriorated. After solving the problem of the bill, the burden on his body increased sharply, especially the burden on his heart, which forced him to enter a rest period. However, a series of things left by the Avengers made Tony unable to rest and recover. So he came up with a way to let Vision use the Mind Stone to assist, upload his consciousness to the Internet, and let his body enter a state of temporary suspended animation and slowly recover.
However, there were some errors when uploading, causing Tony not to remember that he was Tony Stark. He thought he was an AI named Antony, but he still remembered that he had to solve problems for Steve and the others. Then the Team CAP matter was resolved, and Steve and the others returned to Avengers Tower, but did not see Tony...
