One of the most striking characteristics about The Walking Dead this season is its abundance of actors of color. Earlier on in the series, this wasn't the case. Token black characters were the norm, and diversity was lacking.
The biggest character reveal in season 3 of Walking Dead is the sword wielding Michonne. She's the cold, calculated warrior who shows up with two walkers chained to her hip — as protection. This is both insanely fucked up and totally awesome.
