Gordon Watanabe recurs as a middle-aged man throughout the series. He consistently appears without full clothing, though strategically placed objects like sunflowers obscure the view. Characters, particularly Naoto Yamada, repeatedly instruct him to cover his lower half. During door-to-door sales visits, his merchandise occasionally interacts in unexpected ways with others' features, such as Paul Okamoto's mohawk. He also takes to the air on multiple occasions with makeshift artificial wings for eccentric flights. His past includes modeling for Schneider Mori, an association that indirectly led to Schneider losing his hair to a barber and subsequently relying on a wig. His role, relationships, and defining traits remain consistent across different seasons, films, and other media adaptations.
