Batabattan

Batabattan (バタバッタン) is a grasshopper-like enemy from Mega Man 6. While they bear a slight resemblence to the Battan in Mega Man 4, unlike Battan they actually attack Mega Man. Batabattan might be difficult to hit with uncharged shots, due to their movement pattern and size.

Onbuubattan
Onbuubattan (オンブーバッタン) is an upgraded version of the Batabattan. Onbuubattan has a smaller version of itself on its back, which jumps off if the larger is struck or hits a barrier. The Tengu Blade destroys Onbuubattan in one hit if fired in close proximity to it.
