Katz lost his right arm and his only son. Before joining Phoenix Force, he worked for the Mossad, Israel's intelligence unit. Katz was held in high regard by the other Phoenix Force members. After a mission in the Far East, Katz retired from field work and went on to serve as Stony Man's tactical adviser. Katz was killed on a personal mission to stop a terrorist conspiracy in the Middle East, leading Mack Bolan to take up where he left off with support from Stony Man's top operatives and a top Mossad agent. Katz's prosthetic arm featured hooks which could be effective in a fistfight, and could often be replaced with a realistic-looking arm or a version that fired a single .22 Magnum bullet. His age, slightly paunchy appearance and prosthetic arm often caused opponents to underestimate him. Katz's weapons of choice were the IMI Uzi, Heckler & Koch P7, SIG Sauer P226, and a Spetznaz ballistic knife.

Teko challenged the decision and demanded a duel of honor with his successor, who happened to be Keio's father, Toshiro Ohara. Toshiro won the duel, but he and his wife were later murdered by Teko. He later joined up with Professor Edward Oshimi, the founder of the terrorist group called the Japanese Red Cell, in his plot against the U.S. government. However, he and some of his JRC associates were on the Hawaiian island of Lanai when Phoenix Force attacked the mad professor's stronghold, so Keio had no idea of his uncle's involvement until he broke into Keio's apartment and left a note challenging him to a duel to the death on Alcatraz Island. Keio eliminated his uncle's associates before facing him in
