Poyoko

Poyoko (ミノルガー) is an enemy Mechaniloid from Mega Man ZX Advent that has evolved and developed the ability to reproduce. However, its wings have gradually devolved as consequence, and can only fly at low altitudes. It's only a matter of time before they completely lose the ability to fly. They drop egg-shaped explosives. Poyokos appear in the Arctic Ice Floe and the Oil Field.
