Pong Krell

Just the sheer fact that these two literally have subreddits that are solely dedicated to trashing on them shows just how well-written they both are.

Micah has no redeeming qualities, but I don't think that necessarily makes him a bad character. Sure he's openly racist/sexist and a traitor, but a coward? Not really. Quite the opposite actually, he's a bloodthirsty nihilist whose psychopathy dates all the way back to when he was 17. He's also one of the best gunslingers in all of RDR, and he has a few funny moments as well.

Krell's kinda the same story, a racist jerk and a traitor but you can't deny that he's pretty badass. He slaughters dozens of clones all by himself before getting arrested, and he certainly doesn't go out begging for mercy when Rex holds him at gunpoint. He's also a good manipulator and I really like his voice-actor, Dave Fennoy (who voiced Lee in the Walking Dead games).

RIP Arthur and Waxer though. :(
