Appearance Spotlight: Killmonger

Black Panther's Killmonger is easily among the best Marvel Cinematic Universe villains, due to a combination of a sympathetic backstory and goal and being played by the charismatic Michael B. Jordan.

In the comics, Killmonger's backstory is pretty much the same although his goal is exactly the opposite (making Wakanda even more isolationist rather than sharing its technology with the world), but another important difference is their appearance. While the movie's Killmonger where's a leopard-inspired take on  Black Panther's armor...

...the comics version of Killmonger goes for more a gladiator-esque look.

And that's still true today, for this Killmonger. But it's not true for another Killmonger. See, in Black Panther volume 7 by Ta-Nehisi Coates establishes an "Intergalactic Empire of Wakanda" that's some combination of in another reality and 2000 years in the future. I'm a little unclear based on what I could find online. Regardless, many of the people in this storyline share their names with Wakandans we know, including Emperor N'Jadaka, who's named after Killmonger. And his armor looks like this:

Note that it's not an exact recreation, and the MCU's Killmonger certainly doesn't have a cape made from a Symbiote, but it's still close enough that it's easy to tell what they were going for.
