Editing Barry Kahn (section)

==== "Future" Trunks Saga ====
Barry Kahn is cast as the lead in ''Great Saiyaman vs. Mr. Satan,'' playing the Great Saiyaman. However, he becomes jealous of Gohan, who serves as his stunt double and garners admiration, and is envious of Gohan's marriage to Videl. Seeking to ruin Gohan’s reputation and marriage, Barry blackmails his co-star Cocoa Amaguri into arranging a private rehearsal with Gohan to fabricate an affair. Unbeknownst to Cocoa, he also intends to destroy her career through the scandal.

Cocoa, after discovering Gohan's true identity as the real Great Saiyaman and developing feelings for him, tries to thwart Barry by relocating the rehearsal. Despite her efforts, Barry catches them and witnesses Cocoa innocently kissing Gohan as thanks for his encouragement, providing him with material for his scheme. Barry attempts to convince Videl that Gohan has been unfaithful, but Videl dismisses his accusations, seeing through his manipulation and calling him "pathetic." Barry vows to expose Gohan's identity as Great Saiyaman.

Barry's malevolence attracts the parasitic space criminal Watagash, who possesses him. The possession amplifies Barry's power and evil nature, transforming him into a monstrous form. Seeking revenge, Barry kidnaps Pan to lure Gohan into a fight. As Great Saiyaman, Gohan battles Barry, who continues to grow stronger through multiple transformations. Gohan ultimately defeats Barry by transforming into Super Great Saiyaman, freeing him from Watagash's influence. Cocoa ensures Barry's blackmail plans fail by threatening to reveal his monstrous transformation, forcing him into silence to protect his reputation and career.
