- I'll calm down when your head is clean off your body, you stupid bug!
As a teenager, Alex was a wrestler, and dreamed of going pro after graduating. However, his father was in debt to a man named Wilson Fisk, and he sold Alex to him in order to pay it off. Before he even turned 18, Alex belonged to the Kingpin.
Alex became Wilson's body guard, and he was constantly ordered around. He wanted both Fisk and his father to die terrible deaths, but all he could do was fantasize. He couldn't do anything about it. Several times, Alex was forced to fight Spider-Man in order to defend Kingpin.
Once Fisk teamed up with Norman Osborn, they began breeding Spider-Man villains. After two failed projects, Fisk volunteered O'Hirn for the next experiment. Against his will, O'Hirn was mutated into the Rhino.
Alex battled Spider-Man, against his will. Kingpin had inserted a bio-chip into O'Hirn's bloodstream which could knock him out cold if he did something Fisk did not like. After capturing Spider-Man and bringing him back to Fisk and Osborn, Fisk told Rhino he would be shut off until he was needed again. Before anyone could react, he attacked Fisk, knocking the switch out of his hand. When Osborn attempted to grab it, Rhino stepped on his hand and shattered the switch. He got away before any of them could register what had happened.
