The Efrika Plains, also known as the Efrikan Plains, are a region in the continent of Efrika and the territory of the Efrika Dark Egg Legion led by Diesel. With the Bear Pack and Nasty Hyenas united under him, Diesel intended to strike at Mazuri from the plains after learning of Dr. Eggman's supposed demise. However, he quickly learned that the doctor was indeed alive, presumably halting his invasion plans. (SU: #37, CSE)
