The Tattooed Man can touch someone and learn their secrets. He had employed himself as a gangster and a blackmailer for decades. He usually employed henchmen to hold his victims still. It was this way that he blackmailed Colossus' father to keep young Piotr's mutant nature a secret.
When Colossus found him later in San Francisco, he posed as dumb muscle looking for work. He went along with the Tattooed man's goons when they opened a shipping crate containing depowered mutant women from Russia, smuggled into the United States to work as prostitutes. Colossus rescued the women and brought them to the X-Men. Then he and Emma Frost captured the Tattooed Man, and installed him in the X-Brig, a virtual reality prison.
