That said, these differences in origin and characterization show part of the rift that exists between the personalities of these two characters.
These qualities seem specifically worth mentioning because they show some of the critical differences that exist between T’Challa (Chadwick Boseman) and Erik Killmonger.
We know who King T’Challa is going into this movie, but it sounds like Killmonger will be more of a slowly-unraveling mystery as an outsider.
Much has already been said about the fact that Killmonger (at least based on early trailers) looks like a dark reflection of T’Challa’s powers, abilities, and looks.
