Tondeall

Tondeall (トンデオール) is a flying cannon enemy in Mega Man 5. It just floats back and forth and shoots at Mega Man. It appears in Star Man (as well in Mega Man for the Game Gear) and Gyro Man's stages, as well as in the first two stages in Proto Man's castle.

Etymology
Tondeall's name is derived from "tonde iru (飛んでいる)" or "tonde oru (飛んでおる)", which roughly means flying in Japanese.
