Katsudonman forms one-third of the Donburiman Trio, fighting alongside Tendonman and Kamameshidon as their acknowledged smartest member. His speech bursts with Gratuitous English phrases like "Yes!", "No!", "Shut up!", and "Oh My God!", a trait directly linked to the British origin of pork cutlets within his namesake dish. Visually, he adheres to the trio's Color-Coded scheme in blue and white attire. In combat, he launches his bowl-head lid as a projectile Deadly Disc and wields chopsticks for close-range strikes. He executes coordinated group techniques, including the Double-Punch with Anpanman or Currypanman, and the Special Triple-Punch combining forces with both Anpanman and Currypanman. Debuting in the 1989 film *Soreike! Anpanman: Kirakiraboshi no Namida*, Katsudonman later joined the main anime series, where his documented appearances predominantly feature group activities with Tendonman and Kamameshidon.
