Avalanche's past before Mystique recruited him for the second Brotherhood of Evil Mutants is almost entirely unknown, except for the fact that he is an immigrant from Greece. He first publicly appeared with the Brotherhood when they unsuccessfully attempted to assassinate Senator Robert Kelly during his hearings on the menace that mutants allegedly pose to humanity in general. Avalanche briefly left the Brotherhood to attempt to blackmail the state of California into paying him an enormous sum to prevent him from using his power to trigger a major earthquake there. Avalanche fought the Hulk on this occasion, and suffered serious injury .

He has since returned to the Brotherhood. Recently, Mystique offered the Brotherhood's services to the United States government. Their first mission under their new name of Freedom Force was to capture the mutant Magneto, were Avalanche took down Cyclops and Wolverine at same time.

Powers

Avalanche has the mutant ability to generate incredibly powerful vibration waves from his hands. He can use these waves to cause matter to shatter or crumble. When these waves are directed at a building or directly into the ground, they can create effects remeniscent of earthquakes or avalanches. Avalanche does not actually need to be touching an object in order to affect it with his vibrations. He can be some distance away from an object and still be able to affect it. It should be noted that Avalanche's powers usually have little or no effect on organic matter.
