That's what diamond back was and the overall consensus to that was he was "goofy" or from episodes 8-13 the tone was "uneven"
I know that. I said I loved Diamondback. I just didn't like his Luke Cage motivation. I don't think it would have been so even had they had Cottonmouth for him to play off of. When Diamondback debuted, Black Mariah also shifted from level-headed, to slightly unhinged.
