The Dominikos Petrakis version of Avalanche is a Cretan mutant who possesses the ability to generate seismic waves from his hands that are strong enough to create earthquakes of varying sizes and to disintegrate any substance other than living tissue.

Created by writer Chris Claremont and artist/co-writer John Byrne, the Dominikos Petrakis version of Avalanche first appeared in The Uncanny X-Men #141 (Jan.

During his first public appearance with the Brotherhood, the team unsuccessfully attempts to assassinate Senator Robert Kelly during his hearings and testimony on his belief that mutants pose a mortal threat to humanity.

[5] After escaping the fray, Avalanche continues his support of Mutant supremacy via terrorist and criminal activities and battling the Avengers with the Brotherhood.

[6] Avalanche briefly leaves the Brotherhood and attempts to blackmail the state of California into paying him an enormous sum to prevent him from using his power to generate an earthquake.

[18] Freedom Force also has a costly battle with the Reavers on Muir Island where a number of members are killed or seriously injured.

[22] When Freedom Force is disbanded after the botched mission in the Gulf War, Avalanche continues to work for the government as part of Project: Wideawake, but soon leaves when he finds out that his friend Pyro had contracted the Legacy Virus.

When the X-Men moved their headquarters to San Francisco, Petros was frightened that they would eventually come for him for his past crimes.

He can be seen fighting alongside the X-Men Sunspot, Husk, and Boom-Boom, defending the passage of the Bart Tunnels.

As Captain America tries to stop him, he claimed that "the inciting act is complete" and jumped to his apparent death.

[30] A somehow-repowered Mesmero brainwashed the unknown Avalanche into joining his Brotherhood of Mutants which was secretly funded by anti-mutant activist Lydia Nance.

Avalanche's first mission with the Brotherhood of Mutants was to kidnap Mayor Bill de Blaso and held him hostage.

When Mesmero states that the Brotherhood of Mutants are still under Lydia Nance's paycheck, Pyro takes his leave since he didn't want to work for an anti-mutant activist.

[35] The Dominikos Petrakis version of 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 wears an armored battle suit that gives him enhanced resistance to injury, up to and including protecting him from a land mine.
