In "One-Million Year Trip: Bander Book," Black Jack departs from his usual surgeon identity to embrace the role of a space pirate. He retains his iconic visual traits: a distinctive facial scar, dual-toned skin from a skin graft, and stark black-and-white hair. His enigmatic presence and morally ambiguous nature persist, consistent across portrayals, though his profession adapts to this science-fiction universe.

As part of Tezuka’s "Star System" ensemble—recurring character designs reimagined in diverse narratives—his space pirate incarnation embodies unpredictability and duality, mirroring the complex ethics of his medical origins. This inclusion follows Tezuka’s tradition of repurposing archetypes across unrelated stories, reinforcing themes of conflict and pacifism.
