Willing to rule fairly and equitably, N'Dingi was confronted to the tribes rivalry and to the corruption of his administration working with foreign companies to leech Mbangawi resources. His reign signed the end of the grew of that corruption, but not his stopping.
Jonas N'Dingi eventually died, leaving his throne to his son, Joshua, who had been sent studying in England, became there a R.C.X. agent working on the Warpies subject, was wounded and turned into a cyborg before returning to his country, now nicknamed Doctor Crocodile. Joshua will be able to counter that corruption.
The exact relation between Jonas and Samuel N'Dingi is unrevealed in order to ensure the continuity, regarding to the sliding timescale. Samuel is most likely currently Jonas' son, but as his rule is fixed to start in 1961, their relation is a moving subject.
