Robin from Teen Titans Go! In the original series, he was a good leader, cared about justice, and wasn't crazy. In the new series, he's self-centered, a horrible leader, a huge control freak (sure, he was a control freak in the original series, but TTG takes it too far), and shows lots of signs of being insane. I could make a list of all of them, but here's just a few:
While I admit I do like the show in the context that sometimes it's actually pretty good, and while the weakest of CN's original line up (a very high breed for sure this time), at least it's not Johnny Test or Annoying Orange. But the writers clearly are trolls. You can tell these guys
love post-cancellation series Family Guy, as they turned the Titans into the Griffins. But I have to admit, they did something special with Robin. They made him
both Peter and Meg at the same time. As a fan of the original 00's Titans cartoon it is a might offensive, but it's clearly what they're going for. I agree, I really didn't like what they did to him, but I don't really like what they did to any of them. But, again, they
wanted to tick off the audience. They're well aware that the Titans are unlikable jerks this go around. The villains look downright sympathetic half the time. All according to plan.
Though, frankly, watching Beast Boy and Cyborg's antics in this show makes the Thunder and Lighting episode of the first series
very strange. They both have restraint, and they kinda have more of a vitriolic best buds thing going on.
