Possibly a native of Ireland or Scotland, Patrick Mahony was recruited by Mister Sinister to serve as the leader of the Nasty Boys as Ramrod, a group of young mutants whose first and only missions were against the government sponsored X-Factor. However, he and his friend Ruckus were more interested in beer runs and a quick buck than in Mister Sinister's agendas.
In the Nasty Boys' first and only mission against the government version of X-Factor, Ramrod used his powers to great effect against the heroes, but he was ultimately subdued by the multiple fists of Jamie Madrox. Ramrod escaped, and disappeared after Sinister effectively abandoned the Nasty Boys.
It is unknown if Ramrod retained his mutant powers after the M-Day.
Ramrod was a boss of a construction crew who was gravely injured in a work related accident. As part of a diabolical plot of Kerwin J. Broderick to rule San Francisco, Broderick and Moondragon transformed this crew boss into a powerful cyborg.
Broderick then blackmailed Ramrod, by telling him that he could quickly end his life with a poison within his cyborg body. Broderick coerced Ramrod to destroy Daredevil and aid him in his quest to seize power in Los Angeles. Ramrod became a part of Broderick's crew but was ultimately defeated by Daredevil and the Black Widow.
