Alton Vibreaux was born in Baton Rouge, Louisiana. When he become a geologist, Alton was hired by Franklin Fortney to take some measurements of a deep trench right above the San Andreas Fault. When he fell into the Fault while testing an experimental machine, he was believed to have died. Instead, he received super-human seismic abilities, but was horribly disfigured. He searched for vengeance on Fortney, believing that it was his fault that the accident happened to him. Rhodey Rhodes, who had taken up the Iron Man mantle at that time, fought him and prevented him from killing Fortney.
Some time later he caused a massive earthquake in Los Angeles, but was stopped by the Avengers West Coast, and later battled the original Iron Man again.
Vibro was killed and resurrected by the Hand to join an assault against the S.H.I.E.L.D.Helicarrier, destroying it. After the assault, Vibro was gravely wounded by Wolverine as were most of the super-villains and heroes the Hand were using in the attack.
Later, Mandarin upgraded and used him in his plan to finish Iron Man, as well as many other villains of the armored Avenger.
Vibro has the ability to generate high-level seismic vibrations and fire them from his hands as vibratory or concussive force, causing shockwaves, opening chasms, and/or generating earthquakes. He also has the ability to thrust his vibratory force emissions for flight and to generate shields of vibratory force around himself.
