His profile is horrible ... mandika warrior and common stereotypes about violent Africa (light racism).
Mandinka people (outside the castes made of nobles, griots, blacksmiths or shoemakers) are mainly rural subsistence farmers or merchants. They are probably the most peaceful ethnicity in the region, even if they are muslims. They aren't a fighting tribe at all.
Malik Omari is a bad name. Malik means king in arabian and Omari is of Swahili origin (East Africa). The meaning of Omari is "God the highest". His name is everything except mandinka. I could give you a lot of real mandika names and I am not even mandika or african.
Gambia was the only country in the region that hadn't any real independance or civil wars ...
Senegalese wrestlers and the Serer people in Gambia and Senegal would have been a far better and more logical choice for an african gimmick from this region. WWE and gimmicks ...
