In Japan, Pigma Dengar's name is ピグマ・デンガー (Piguma Dengā).

His surname seems to come from the Kansai expression, デンガナマンガナー (Denganamanganā). In the Japanese version of Star Fox games, Pigma tends to speak in Kansai dialect like people from Osaka. In Japan, people from this region are characterized as rude, bad-mannered, and even criminal lowlifes, very befitting of Pigma.

It is worth pointing out, however, that this is considered an offensive stereotype of Kansai people, and they do not enjoy being characterized this way in Japanese media.
