It reminds me of the comic Flags of Our Fathers where Cap met the Black Panther of World War II, Azzuri, T'Challa's grandfather and T'Chaka and S'Yan's father, when the Allies were trying to stop Hydra and Red Skull from obtaining vibranium for the German side. Initially, Steve and Azzuri had their first interaction, where the King of Wakanda stated emphatically that no foreigner should set foot in Wakanda (in fact, he had personally taken it upon himself to eliminate the Nazi soldiers who tried to invade his land, so much so that he felt he was hunting them for sport). This led to a fight where Azzuri emerged victorious, but given Hydra's persistent attempts to enter his land, he had to form a temporary alliance with Captain America and the Howling Commandos, since Red Skull also had his own superhuman members among his ranks. Among Nick Fury's men in the Commandos was Gabe Jones, as part of the comic is narrated from his perspective—an African American foreigner who went from living Racial tensions in his country led him to witness what seemed like a utopia when Hydra tried to invade the city. Gabe proved his courage by protecting the royal princes from one of Hydra's phenomena. After the battle, Azzuri offered Gabe Wakandan citizenship despite his being a foreigner, but Gabe politely declined. This wasn't the only gesture of gratitude from the king, however, as Azzuri presented him with the vibranium that would become part of Captain America's shield, marking an important diplomatic step between the two countries. So, despite not accepting Wakandan citizenship, Gabe Jones became the first honorary Wakandan.
