In the first episode ofWhat If .

Well, if that man is T’Challa, it can change the fate of the entire universe.

And though T’Challa loves his homeland, he believes it’s been destroyed thanks to Yondu’s lies.

The funniest thing about the episode is how much better T’Challa is at being Star-Lord than Quill was.
