Gangu is the invention of Dr. Ein, best friend of Bongo and tutor for White Bomber. Gangu is chatty, self-centered, annoying and is also one of the members of the Jetters. Bongo upgrades Gangu numerous times into random objects to help with their missions and daily life; Gangu dislikes this and even wished that Bongo wouldn't upgrade him.

Gangu is portrayed as a humorous character throughout the series. He would occasionally break the fourth wall.



Bongo often tinkers with Gangu, usually modifying him to be useful ("useful") in various ways.
