Katsudonman recurs throughout the Anpanman franchise, distinguished by his prominent mustache and his role as Tamagodonman's older brother. He joins Tendonman and Kamameshidon to form the Donburi Trio, frequently appearing together while also undertaking independent episodes. The trio often debates their individual strengths, highlighting their competitive group dynamic.

His personality emphasizes intelligence and knowledge. He habitually shares observations assertively, prefacing statements with declarations like "I know" or "I saw," cementing his reputation as the group's unofficial "smart one" who relays witnessed events. A cultural trait involves his sporadic use of English phrases like "Yes!", "No!", "Shut up!", and "Oh My God!"—reflecting the English origins of pork cutlets, which inspire his name. Western adaptations, such as the Tubi English dub, occasionally omit "Oh My God!" due to cultural sensitivities in children's programming.

As a prominent ensemble member, he anchors comparatively fewer solo episodes. Beyond his debut, he leads roughly 10 stories, some co-starring his brother Tamagodonman. His series presence thrives on group interactions, particularly his dynamic with Tendonman and Kamameshidon, including their rivalries.
