Harold Stanch was a murderer, having seemingly killed several women. He was one of the individuals experimented on by Weapon X Program Director Abraham Cornelius in order to make a better soldier than his previous creations like Wolverine. But after being saved by Logan before his death, Harold was taken into custody until another subject calling himself Sharp set him free. Harold joined Sharp along with the other test subjects as they fought their way through the compound. Harold left on a helicopter with Sharp and the others.
