put it like this Black Panther is one of Marvels most powerful person but Marvel love to dumb him down or write him not up to his abilities like they do to alot of black superhero's and mutants.
Look how they did Synch who was supposed to be one of the most powerful mutant ever and how they did Prodigy im going to make a thread about black comic characters in Marvel and how marvel kill them off, depower them or write them down.
But not to take anything from Luke Cage who is very powerful himself who should be the Leader of the Avengers
