Who should be the villain in the Black Panther movie?

Many people were not familiar with Black Panther until this years Captain America Civil War let alone the characters villains, so here are 3 possible villains I think they could use.

1. Klaw
Most people probably missed Klaw in the movie Avengers 2: Age of Ultron. Klaw had a small cameo selling Ultron vibranium. Klaw isn't someone many people are familiar with. Klaw was one of Black Panthers first villains he was a German soldier who snuck into Wakanda and attempted to steal vibranium but he was stopped by Black Panther. The movie version of the character does not appear to have any superpowers but the comic version has a number of superhuman abilities but mainly he has the power to produce sound waves.

2. Man Ape
Not many people rival Black Panthers physical prowess let alone surpass it. Man Ape is a native of Wakanda who wanted the throne and to gain strength he killed a legendary white gorilla and ate it's flesh gaining tremendous strength. Man Ape challenged Black Panther for the throne of Wakanda but was ultimately beaten.

3. White Wolf
White Wolf is Black Panthers adoptive brother and who hasn't been confirmed as of yet to exist in the MCU yet. With the casting of Michael B. Jordan in the Black Panther movie I assume he will have a major role so hopefully they're thinking White Wolf.
