History
After the separation of the two sides, Colossus fought on the side of Captain America with the Blue. He was tasked to run Project Bellcurve and secret operation to design a weapon that could remove all non tech based powers from people. His first test subject was Sandman and was successfully able to to strip his powers. However, he needed more resources that were only available in the Iron.[1] Peter Parker was sent in and after suffering some casulties was able to retrieve the items and allowed hank to finish his device and create an explosive version of it.[2]
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 which stripped all of the people of their powers.[3] His fate afterwards is unknown but it is presumed he lost his powers.
