History
Iron Man was part of a secret society known as the Illuminati who were dealing with the destruction of multiple Earths due to the events of Incursions. Captain America contacted Iron Man to find out if anything was going on at home as he had a bad feeling about something.
After the Avengers defeated the Builder Armada, Iron Man and the others had to contend with the mad titan Thanos who blackmailed his way to become the leader of the Avengers and wanted Captain America's seat among the table after he killed Rogers.[1]
