Description
Action Bastard is a fictional superhero character from the television show that the main character, Shinnosuke Nohara, adores above almost all else. He is presented as a live-action hero within the world of the series, similar to a cross between Superman and Ultraman, and is the star of his own highly popular program that Shin Chan never misses. The in-universe actor who portrays Action Bastard is named Gotarō Gō, a movie stuntman by trade.

The personality of Action Bastard, as depicted in his show, is that of a typical tokusatsu hero: brave, powerful, and dedicated to fighting evil. His primary role in the story is not as an interactive character but as a major cultural touchstone and the central object of Shin Chan's imagination and play. Shin Chan owns a vast collection of Action Bastard toys, books, and merchandise, often imitates his signature moves, and has stated that he hopes to become Action Bastard when he grows up.

Action Bastard has a defined set of supporting characters and villains. His main ally is a sidekick named Lollipop. His evil nemesis is Meke Meke, a villain who embodies all that is evil, including a habit of smoking cigarettes. In the English adaptation, his rogues' gallery expands to include more parodic antagonists such as the Flying Pecker, a brainwashed former flame of Lollipop, and the diabolical Dr. Hitlerclone. The storylines of his show often involve high-stakes battles, doomsday devices, and complex, if absurd, plots, such as the secret of the "Lucky Bastard Fever" armor.

In terms of abilities, Action Bastard possesses a range of fantastic powers typical for a superhero of his genre. He is known to use attacks such as the Action Beam and the Action Beam Ball to defeat his enemies. The action sequences in his program are violent but in the stylized fashion of children's tokusatsu productions. The character himself does not undergo development, as he is a static, fictional hero within a fictional show. Instead, his role in the larger story is to provide a constant source of inspiration for Shin Chan's antics, a vehicle for parody of superhero and sentai tropes, and a recurring source of comedic material, with episodes of Shin Chan often being interspersed with segments of the Action Bastard program itself.
