Psyko Pigs are the grunts of the Dark Queen's army. As their name suggests, they are pig men. Psyko Pigs are generally seen wearing leather armor and horned helmets. In terms of weapons, Psyko Pigs tend to carry large axes or maces. They will also use their considerable bulk to try and crush an opponent.
It is suggested that Psyko Pigs are led primarily by General Slaughter, but they are likely under the command of the mysterious Admiral Oink.
