Efrika was once home to Kodos Lion before he relocated to the Kingdom of Acorn, and was also home to King Leonus. Unfortunately, the wild region also produced vicious gangs like the Bear Pack and Nasty Hyenas, who were later united into the Efrika Dark Egg Legion under the command of Diesel.

- Efrika is the Mobius version of Africa.
- The name of this continent was introduced in an entry on the Sonic the Hedgehog comic blog detailing E-102 Gamma's mission to locate and "liberate" the remaining E-100 Series robots of the Eggman Empire. 
- Proceeding Soumerca, Efrika was the first of several regions of Mobius revealed to have survived the events of Worlds Collide with its original name intact. Mercia, Downunda, and the Northern Tundra were renamed Avalon, Tralius, and Artika respectively.
