Gengu is a Cappy and resident of Cappy Town in the anime series Kirby: Right Back at Ya!. Gengu is an exceptionally portly Cappy who runs the toy store in the town. In addition to receiving toys from external shipments, he is also capable of making them himself.
Gengu is recognizable by his short and stout physique, along with his orange overalls and accented cap. Through the series, he is not shown to be particularly clever, but he is always helpful and cares about his customers. In his first starring role in the episode Kirby's Pet Peeve, he attempts to make a replacement Electronic Pet for Kirby after the original is lost at no charge, but ultimately decides against presenting it to Kirby, since nothing he could make would be a suitable replacement.
