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.
