When I say the Black Panther and Captain America go way back, I don’t just mean to the early days of the Avengers! Yesterday I shared a few panels from when T’Challa met Steve but today we’re going all the way back to WWII. According to the most recent version of the story, Cap once was sent to Wakanda (in search of Nazis, of course) and was met by Azzari, T’Challa’s grandfather. Azzari had already taken care of the Nazis and asked Cap to leave. He had to be persuaded.

-We Are Wakanda
Aka; that time Cap showed up uninvited, was asked to leave, & ended up getting put out on his ass by Black Panther.
