Fly Boy (フライボーイ Furai Bōi?), also known as Prop-Top in the Mega Man 2 instruction manual for the U.S., is a pogo-like toy that was modified by Dr. Wily into a robot that attacks by pressing its target. They appear infinitely from the top of the screen. After landing, they levitate up slowly for a bit, try to crush Mega Man swiftly, and repeat.
