Iron Man 3[]
The suit was created after the New York battle. Tony realized that there couldn't be one suit that could do anything, so he started building suits specializing in certain areas. Piston was placed into the Hall of Armor along with the rest of the Iron Legion. When the "House Party Protocol" was ordered, it and the rest of the Iron Legion flew to assist Tony in the Extremis battle. It was destroyed by the the Extremis soldiers.
