|Season:||Engine Sentai Go-onger|
Happa Banki (ハッパバンキ Happa Banki?, 17): A dynamite (ダイナマイト dainamaito?) Savage Earth Barbaric Machine Beast, Yogostein's "number one hooligan" and ends his sentences with "dappa." He is sent to destroy the city with his Dynamite Don-Don attack until the Go-on Wings interfere. Teaming up with Yogostein and Hiramechimedes as part of a trio, Happa Banki overwhelms the Go-ongers until the Go-on Wings arrive. He is scrapped by Go-on Gold after he takes his Bikkurium, preventing him from growing, and instead making him explode. His name comes from the Japanese word for "rock blasting" (発破 happa?).
