- Eric Killmonger
You need a villain. Many years ago, Ulysses Klaw led a treacherous attack on Wakanda and its royal family. Klaw even managed to kill the king, T'Chaka, before being stopped by T'Chaka's young son, T'Challa. Klaw was repelled and left Wakanda, but not before he took back a number of Wakandans to serve as his slaves. One of these was a boy whose parents Klaw had killed, a boy named N'jadaka. Little is known of N'jadaka's time as a slave to his parents' killer, but we do know that N'jadaka harbored an intense hatred for T'Chaka, his former king. He believed that weakness on T'Chaka's part was a key factor in allowing his parents to be killed. N'jadaka became educated in the United States, adopting the name Erik Killmonger, earning a PhD in Engineering and an MBA. It is said that he even taught for a time at M.I.T.
To this day, the Black Panther has never defeated Erik Killmonger in one-on-one combat.
Killmonger is a revolutionary leader, well-known to all Wakandans, and even supported by some. The village he grew up in has even been renamed N'jadaka Village. His revolutionary charisma, his mastery of politics and economics, his tactical cunning, and his access to the Altar of Resurrection would likely have make him Black Panther's greatest foe even if his physical abilities were not as amazing as they are.
Ulyssess Klaw -
Klaw's origin has recently been ret-conned by Reggie Hudlin in the Black Panther series. In this version, his great-great-great grandfather was one of the founders of South Africa, whom T'Chaka killed in a fight. Klaw is now an assassin, hired to kill him. Ulysses Klaw, a Dutch scientist, had developed a weapon that could turn sound into solid objects - as before, it needed only Vibranium to work finally. Klaw makes his move at a global economic conference where plenty of 'potential employers' gathered. When Klaw realizes no deal is going to be made, he takes action, managing to kill the Panther. During his escape, Black Panther's son T'Challa blasts Klaw's hand off. After having his half-dead body experimented on for close to a decade, Klaw returns to being an assassin. With a gun attached to his hand, and Vibranium from the black market, he returns to Wakanda ten years later, as before, attacking Black Panther and the Fantastic Four.
You need villains for the character to rise up against and defeat. BP has never beaten Killmonger. And fighting Klaw who's a city wide type/ team threat would be excellent to have. Where BP would use his genius intellect to beat Klaw. Killmonger you have BP fight him and "Lose" and then have Killmonger come back for another movie.
You introduce the Dora. You introduce Shuri. You have to see BP's family and how he runs his kingdom. You have him mention where he was educated at. You have him mention his capabilities offhand. And then you show him working in a lab. You show him creating inventions. You show him working out.
I'd even start it off in 2 phases. You start it off with T'Chaka being killed. Then you do the scene where T'challa fights for leadership of the Black Panther cult. And taking up the mantle. And meeting Bast. After that fight. You show a spanning view of Wakanda. You show them with flying cars and towering buildings with panther symbols all over. Then you show the vibranium mountain. You introduce Klaw there, in my view though. You have Klaw be hired to steal vibranium from the mountain by Killmonger. Who we meet soon after.
When you do focus on Killmonger you show him brutally killing 1 of the White Gorilla's with his bare hands. After that kill 1 of his aids comes up to him with papers to sign or some shit like that showing he's not just some savage ass dude out there. Next scene you see him in an office handling business and being reported to by Klaw. The whole beginning of the film needs to show Killmonger causing trouble in Wakanda. Middle of the film has to show him maybe leaking information to the Americans about Wakanda. You have Cap America in on a meeting with SHIELD about how the hell Wakanda could've gone undercover for so long and you have cap flashback to meeting TChaka and being beat by him.
America sends an emissary to wakanda. Tchalla says fine. Since we're already exposed, i'll meet them. Killmonger serves as an envoy with the Americans and and that's where we learn Killmonger's history. During their meeting where Tchalla spanks everyone involved verbally except Killmonger...Klaw causes a bunch of bullshit at the mountain. Causing it to quake and Shuri is in the mountain leading a tour. Killmonger and Tchalla go into the mountain to help people together and face down Klaw and his weapon. Tchalla and Killmonger get separated and Killmonger uses a machine that kills Klaw's physical body but turns him into energy making him the hero of the people.
And as usual i'm stuck there. Anyway big fight with Killmonger at the end at the same time figuring out a way to technically stop Klaw's energy form from further fucking up Wakanda. And MAYBE... at the end fly in a Helicarrier.
...probably not...lol
