Bari III (バリⅢ Bari III) is a tower-like enemy from Mega Man 10 that attacks with sound waves. The small sections below it can be destroyed, and the top of its head can be used as a platform; standing on it for a period of time forces it to lower. They appear in Sheep Man's stage, Wily Castle 1 and Wily Castle 2. The Triple Blade is the best weapon to use as it can not only destroy it with one hit, but it can also cut it down. When standing on top, Mega Man can kill Bari III with the Ballade Cracker and Bass can with his buster.
Its name is probably derived from Japanese teen slang "bari san (バリ3)". This word is an abbreviation for "baribari sanbon" (バリバリ3本, active three bars), refers to signal level icon (tower and waves) for Japanese mobile phone.
