Avengers: Age Of Ultron Spoilers - 16 Things We Know Will Happen
6. Ultron Goes To Wakanda
With the Black Panther movie confirmed and strong suspicions that the character is being groomed to take over the Avengers in the long term - after Stark "retires" and Cap is killed - a cameo for either him or his nation is to be expected sooner rather than later. And with Ultron going through an evolution to become Ultron Prime by the end of the film, which enables him to break Cap's shield (as suggested by the trailer), it would seem the villain ends up in Wakanda mining their most famous export. Since Cap's shield is made of Vibranium, the only substance capable of breaking it would presumably also be Vibranium, which isn't exactly plentiful. And thanks to Andy Serkis being on the bill as "Klau", you have to suspect that Ultron gains knowledge of the metal from his indirect contact with Von Strucker's forces (through the Twins). That would then feed into Black Panther's movie, with Klau (and amalgamation based on famous villain Klaw) promoted to primary antagonist.
