|Game: Sonic Chaos|
Bane Motora, (バネモトラ) (referred to as Boing-o-Bot in the US manual) is a badnik found in Sonic Chaos, a red version being found in Turquoise Hill Zone while a blue version is found in Mecha Green Hill Zone. They are based off of Sonic 1's Moto Bug (named "Motora" in the Japanese manual), but have a spring attached to the top, meaning they can only be destroyed via the sides.
Turquoise Hill Zone's boss, Great Bane Motora Gold is a bigger version of this badnik.
