History
After the separation of the two sides, Colossus fought on the side of Captain America with the Blue. After the assassination of Miriam Sharpe, Tony tried to secretly send a drone into the Blue in an attempt to follow the trail. However, this was destroyed by Storm who delivered the destroyed drone to Colossus who, with the help of Magneto returned the scrap of the drone to the capital of the Iron.[1]
He was later present at the Battle of the Divide fighting several of the heroes of the Iron. He along with everyone else on both sides was telepathically informed of the Skrulls deception and went down to the Divide when both Stark and Rogers activated the bomb developed by the Bellcurve Project which stripped all of the people of their powers.[2] His fate afterwards is unknown but it is presumed he lost his powers.
