|Season:||Engine Sentai Go-onger|
Engine Bus-on (炎神バスオン, Enjin Basuon?) is Go-on Blue's partner, a hybrid between a lion and a bus who is the Edokko spirit of the group and ends his sentences with "Onon Ooonn!" (オンオン！, On'on!?). He is able to hold 100 to 200 people in his body. When fully introducing himself, Bus-on says, "The chic and gallant safe ride! I'm Engine Bus-on" (粋でいなせな安全運転！炎神バスオンでい, Iki de inase na anzen unten! Enjin Basuon dei?). He has brute strength and Bus-on Missiles (バスオンミサイル, Basuon Misairu?). He uses his destination sign as a secondary form of communication, changing it to say words such as "Stop" and "Fire!" He forms Engine-Oh's hip, legs, and Go-on Sword. Bus-on is voiced by Hisao Egawa (江川 央生, Egawa Hisao?).
