No he did not. The first thing he talked about with the character was how he didn't understand what made him so cool and then he did research. I just want to know what research he did.
Tchalla doesnt shoot lightning from his eyes
Tchalla doesnt have bulletproof skin
Tchalla cant alter reality
Its a very nuanced character and it's not for everybody at first until they actually do research. I just wish Marvel would give the character to people that actually understand all of his nuance.
