Avalanche projects vibratory waves from his hands. In his first appearance, he used his power to disintegrate objects, especially those made out of earth and stone. His power has no effect on human or animal tissue. Nowadays, Avalanche generates a type of seismic wave that he sends through the ground, allowing him to control the surface in many ways. He can cause the ground to move like a tidal wave to bury people, or even ride the wave for transport. His power is ineffective on organic objects, which reflect his waves back at him. Avalanche is mortal, but a supernatural deal he may have made (see Uncanny X-Men #255-56) may make him very hard to kill. When Freedom Force was disbanded after a botched mission in the Gulf War, Avalanche continued to work for the government in Project: Wideawake, but soon left when he found out that his friend Pyro had the Legacy Virus. Avalanche spent a lot of his time afterwards trying to help find a cure for his friend's condition, but it seems he has given up in recent days.
