Prop-Tops are hostile robots built by Dr. Wily. They are based on the enemy of the same name from Mega Man 2.
Cartoon
Dr. Wily sent some Prop-Tops to California Games to generate "competition energy" by attacking the N Team and the Northridge High Football Team. They barricaded themselves in the Northridge High School gym, but one of the Prop-Tops flew through a window and flew around the gym making strafing runs. Kid Icarus stopped the Prop-Top by shooting it with a Net Arrow, which caused it to fall into a garbage can and explode.
