Dondokomon

Dondokomon (ドンドコモン)
A festival-loving Digimon that will appear out of the blue wherever there is a commotion and pound out a heated rhythm, livening the place up. Its unique rhythm, as well as its beats that will shake one's body to the core, stimulate the listener's nerves and gets them completely excited. Although it is sure to get people fired up at competitions, if by some chance Dondokomon shows up at a brawl, it will definitely grow into a battle royal which swallows up even the excited onlookers, causing a catastrophe. Although its sole intention is to provide its support, once it sounds its "Dondoko Ondo", which raises the tension between friend and foe alike, there isn't anything that will settle the commotion. Anyone who interrupts Dondokomon's performances will be punished with its Special Move "Midareuchi Rush", which fires shock waves at random.

Etymology
Dondoko: Dondokodondon (ドンドコドンドン), the matsuri ji which is used in traditional Japanese music, in particular while performing with the taiko at Japanese festivals.
