The quest for a complementary regional hegemonic dispensation has been an enduring component in Africa. While studies have recognised the increase in power assets of some states within the continent, literature is replete with the idea that no state can equal or defeat Nigeria and South Africa in contesting for regional powers. Though, this impression appears plausible. However, there are limited scholarly contributions to the devastating conditions that undermined the regional powers’ influential position to enhance legitimacy and positive image-making for African rebirth in global politics. It is against this backdrop that the current effort examines the constraints that hinder the credibility and attractive assets of the two regional powers in African policy. Relying on key-informant interview and secondary sources for the collection of data and the interpretive qualitative method for data analysis, the findings reveal that domestic limitations are major impediments to regional hegemonic powers’ dispensation. This article argues that possession of remarkable material capabilities without corresponding legitimacy and diplomatic means of ‘appealing’ to other states is not enough in the pursuit of hegemonic status. It, therefore, concludes that Nigeria and South Africa must tackle the domestic crises that consistently decline the credibility and continental leadership to curb the global inequality against Africa.
