Avalanche (Marvel Comics)

Avalanche is a mutant with the superhuman ability to generate powerful seismic waves from his hands, creating highly destructive effects. The waves can cause an inorganic object to shatter or crumble into dust and has in recent years been shown to affect organic matter as well. When directed against large objects like buildings or upon the earth itself, the seismic waves can produce effects similar to those of an earthquake or avalanche within limited areas. Avalanche need not touch an object to affect it; he can direct the waves against it from some distance away. Avalanche himself is immune to the generation of his own vibratory waves. However, if the seismic waves were reflected back at him, he would be injured. Avalanche's power originally had little or no effect on organic tissue, with the reflected vibrations from organic matter ("feedback") injuring him, as when he once tried to attack the Hulk, but lately this has appeared to no longer be the case. As yet there is no known limit to the amount of area upon which Avalanche can use his powers at one time. There is no evidence yet, however, that he could create an earthquake capable of destroying an entire city.
