History: 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 hearins 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 (see Limitations). 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.

Strength level: Avalanche possesses the normal human strength of a man of his age, height, and build who engages in moderate regular exercise.

Known Superhuman Powers: Avalanche is a mutant with the superhuman ability to generate powerful waves of vibrations from his hands, creating highly destructive effects. The vibrations can cause an inorganic object to shatter or crumble into dust. When directed against large objects like buildings or upon the earth itself, the vibrations can produce effects similar to those of an earthquake or avalanches within limited areas. Avalanche need not touch an object to affect it: he can direct the vibrations against it from some distance away from it.
Avalanche is himself invulnerable to the effects of generating these intense vibratory waves. However, if the vibrations were to be reflected back upon him, he would be injured.

Limitations: For unknown reasons, Avalanche's power has little or no effect on organic tissue. When he once used his power against the Hulk, the Hulk was uninjured, but the resulting feedback shattered the bones of Avalanche's arms (which have since completely healed). Hence, although Avalanche's vibrations have little or no effect on organic tissue, the reflected vibrations ("feedback") can injure him.

As yet there is no known limit to the amount of area upon which Avalanche can use his powers at one time. However, there is no evidence that he could create, an earthquake capable of destroying an entire city.
