Over time, Colossus' wounds healed, but he was trapped in his armoured form and could maintain his human form only with the utmost concentration. When he saw the X-Men in Dallas during the "Fall of the Mutants", he had his sister teleport him to the battle, as Destiny had not seen him in her vision of the X-Men's demise. When the team decided to sacrifice themselves to stop the Adversary, Colossus gave his life alongside them to save the world. Like the rest of the X-Men, he was revived by Roma and decided to let the world believe him dead while he and the X-Men worked out of an Australian base.
