Nth Man: The Ultimate Ninja is a comic book about an American ninja set in an unspecified near future where World War III has started. It was written by Larry Hama between 1989 and 1990, based largely on his success writing the G.I.Joe: A Real American Hero comic, which he wrote concurrently with The Nth Man (and also features a modern ninja as one of the main characters). Nth Man and Alfie O'Meagan first appeared in Marvel Comics Presents #25 (August 1989).

The series starts in medias res with American soldiers parachuting into war-torn Moscow in an attempt to rescue the Nth Man. Using TV news commentary as a plot exposition device, it is revealed that the war was caused by Alfie using his psychic abilities to neutralise all nuclear weapons on the planet and upsetting the balance of power.

As the story progresses, we learn that Alfie has grown up in an orphanage alongside John Doe (the "Nth Man" of the title). Doe was adopted by an elderly Japanese man who worked for the CIA's "Black Ops" division. Doe was raised as a ninja, taught to kill without regret.

While in the orphanage, O'Meagan had visions of possible futures (the "could-be's") and over time, his powers grew so that he was able to control matter and produce other effects that were against the physical laws of the universe.

Nth Man has not been a contender in any CBUB matches.
