It was subsequently replaced by a spin-off title, Action Man: A.T.O.M., published by Panini in as a tie-in with Hasbro's recently-launched A.T.O.M.

[3] The comic strip was the main feature for each issue, with the narratives invariably focusing on Action Man's efforts to thwart the evil plans of his arch enemy, the mad scientist Dr. X, and his 'Council of Doom'.

Action Man had to explore Island X in his quest to find the Doctor's base, with several confrontations ensuing before their final battle in issue #100.

The central plot for this story arc centred on the new villain 'No-Face' creating an army of 'X Robots', built in the late Dr. X's image, to spread terror across the world before later resurrecting Dr. X as a cyborg.

No-Face then kidnapped a scientist named Professor Moran and forced him to make a mind control gas for Dr. X, which could help the doctor achieve his goal of taking over the world.

The story arc culminated in issue #119, published in November 2004, where Moran was ultimately rescued by Action Force and Dr. X temporarily defeated.

The 2004 direct-to-DVD film Action Man: Robot Atak adapted this story arc, with the DVD being given away as a cover gift with the comic.

A direct to VHS and DVD film titled Action Man: X-Missions - The Movie was also released in 2005 and featured some similar plot elements.
