Black Panther has and never has been as much of a failure as Carol. He has ALWAYS had a dedicated fanbase and has never tanked a series as often as she does.
She has failed four times. That's not an exaggeration, either.
If I said "Black Panther" to a random stranger, even before the movie came out, they would think "King of Wakanda". I say "Captain Marvel" to someone, and what do they think of? Something, something, avengers?
She has never been strong enough to carry her own series. Every attempt Marvel has tried has also failed. Black Panther didn't sink four different series and several crossover events with just how repugnant and hated he is. On the contrary, Black Panther has saved crossover events before by being one of the few characters in it who can be classified as a leader.
In comparison to Black Panther, what the fuck does Captain Marvel have? Most people don't even think of her when they think 'Captain Marvel'.
She was the scourge of marvel comics just a couple years ago, and now you're trying to compare her to Black Panther. I think you should apologize to Black Panther right now.
Stupid fucking drones have the brains of silly putty.
