Beyond that, Black Panther simply would’ve been the easiest way to check in with Nick Fury/Samuel L. Jackson, as we have not seen him on the silver screen since the events of The Avengers: Age of Ultron.
The odds of him showing up in Thor: Ragnarok seem minimal, and as of right now it looks like he will not appear in either of the upcoming Avengers movies.
Black Panther arguably would’ve been the easiest Earth-based Phase 3 movie to include him in before we go back in time for Captain Marvel, so it’s surprising to see that the studio has kept this fan-favorite character on the back burner for so long.
