Plugger

Plugger (プラッガー) is a plug-like enemy in the airship (the midstage that Kuwagust Anchus appears in) of Mega Man Zero 2. When Ciel is hacking the airship that is attacking the Resistance Base, the Pluggers teleport to the cockpit and attack. Some will charge at ZeroXorZ and Ciel while others will fire energy shots. After keeping Ciel alive for a certain amount of time, she will finish and they will disappear.
