Rompers

Rompers (ロンパーズ) are miniature walker soldier enemies in Mega Man 8 and Mega Man and Bass, and these tend to inhabit the circus/carnival related stages, like Clown Man and Magic Man's stages. In Clown Man's stage, some are dropped from a large balloon carrying them. If they reach Mega Man, they will latch on to him to impede movement and drain energy (in Mega Man 8) or shake Bolts off (in Mega Man & Bass). In Mega Man and Bass, they also appear in King Stage 2 and Dr. Wily's Stage.

In Mega Man 8, they are orange-colored. In Mega Man and Bass, they are green.

Balloonn
The Balloonn (キキューン) is the Rompers' main aircraft. One Romper uses binoculars to guide the other, and they drop capsules containing the annoying robots. These balloons only appear in Clown Man's stage from Mega Man 8. Obviously, it's name comes from balloon (気球 kikyū).
