Leland McCauley IV was the only son of billionaire industrialist, Leland McCauley III, a business rival of RJ Brande. When he was kidnapped, the Legion of Super-Heroes came to rescue him, although neither he nor his father were noticeably grateful.
Some years later, as an adult, Leland McCauley IV resumed his father's vendetta against RJ Brande. He employed an agent, Charon, to infiltrate Brande's staff on Brande's private planetoid. The agent was thwarted by members of the Legion, though the resulting attack caused a great deal of destruction and risked lives. When the Legion attempted to interrogate the agent, he replied that he knew they couldn't kill him because of the Legion code. Brande, who was not a member of the Legion, then threatened to kill him. Later the Legion broke into McCauley's fortified headquarters in the Himalayas to return the defeated assassin.
