Avalanche is a mutant and recurring antagonist of the X-Men who first appeared in Uncanny X-Men #141 (January 1981). Avalanche's real name is Dominikos Ioannis Petrakis and he was originally from Crete, Greece. A professional mercenary, he first appeared alongside Mystique and the Brotherhood of Evil Mutants in an assassination attempt on Senator Robert Kelly. Even though the attack failed, Avalanche and the Brotherhood continued on with other attacks of terrorism for mutantkind. When not with the Brotherhood, his own personal criminal career involved attempting to blackmail California for a large sum of cash or he'll trigger a huge earthquake, but was stopped by the Hulk. Later on, his friend and fellow Brotherhood member Pyro was infected with the Legacy Virus and he tried to find a cure for him, but ultimately failed. After M-Day, he was one of the few mutants to keep his powers and he decided to leave the life of crime and open a bar in San Francisco. Avalanche has the ability to to create seismic waves from his hands that affect inorganic material to shatter or crumble.
