Kurt Wagner was shunned at birth due to his demonic appearance, which included blue skin, pointed ears, fangs, and a long pointed tail. Nearly dying during the massacre of the Morlock population by Riptide, Kurt was taken to the Muir Island mutant research facility to recuperate. Lead to believe that the X-Men had died in Dallas at the hands of Adversary, Kurt carried on, later becoming one of the founding members of the British super-team, Excalibur.
