Marvel has another hit on their hands with Black Panther, a movie that is competing on an Avengers-level at the box office in no small part thanks to its design, hard-hitting themes, and genuine charm. However, the element that seems to be making one of the strongest impressions is the villain of the story, Killmonger. Played with equal parts intensity and swagger by Michael B. Jordan, Killmonger has already risen among the ranks as one of Marvel's best villains. The character is really resonating with a lot of people, which only leaves us to wonder what the inevitable Black Panther 2 will do without him.
Black Panther 2 is pretty much a certainty at this point, but the sequel will likely need to find a new villain to trouble the lives of T'Challa, Shuri, Okoye, and Nakia. Unfortunately, Black Panther does not have a very strong rogues gallery and the movie already used up his two most prominent baddies. That's not to say that there aren't options, and when it comes to Black Panther 2, these villains could be the perfect fit for the sequel.
If I had to wager money (and I wouldn't; Marvel is much smarter than me), I would bet that Achebe is the best choice to be the villain of Black Panther 2. He doesn't look like much, and he's not the most well known Marvel villain, but this guy is SERIOUSLY deranged. His background is mostly unknown, but it's said that he sold his soul to Mephisto after some soldiers burned his farm, seduced his wife, and left him for dead. He then killed anyone who was even remotely associated with the event and then began his climb to power. Through manipulation, he made his way to a seat of power in Wakanda and was almost crowned king at one point. He's a master manipulator and even a master planner like Black Panther has trouble dealing with him.
This one likely needs lots of fiddling around with, but Malice would make an interesting choice for Black Panther 2. In the comics, Malice is actually Nakia, who is played by Lupita Nyong'o in the movie. They might as well be two different characters. Comic book Nakia is violently obsessed with Black Panther to the point where she tried to murder his one-time girlfriend. Then, when she was kicked out of the Dora Milaje, she fell in with Killmonger, who used a whole bunch of hocus pocus mumbo-jumbo to give her superpowers, dubbing her Malice. She then tried to kill all the women in Black Panther's life, but it obviously didn't work out for her. I have a really hard time picturing Nakia's storyline going this way, so Marvel may introduce an all-new character to be Malice instead.
