(Now before I say anything, to keep the fanboys from attacking me, keep in mind that this is my OPINION:)
Honestly, His fighting style is extremely mediocre and easy, but also predictable and boring. I believe he contributes absolutely nothing to the story except being a staple african american character, and I believe that's the only reason they keep him in the roster is to not be called out for 'racism.'
He's very stereotypical, he's boring, he's a wasted roster spot that could of been used for other characters. A majority of the world who knows him dislikes playing him.
I can go on for days but I've probably already pissed off quite a few people while typing this I'm sure.
That's my opinion and slightly a few facts. I will literally never play as him unless I absolutely have to.
