I think this is a valid comment and shouldn't be dismissed just because it's a different opinion. For what it's worth, I like Robin as a badass and really enjoyed playing as him in the game. I think Robin deserves to beat up baddies with finesse just as much as Batman. However, I know where you're coming from. Sometimes, Robin's role is to showcase Batman's humanity and camaraderie. It's easy to see this in TAS, especially the Christmas episode in which Dick tries to get Bruce to watch It's a Wonderful Life. Robin can be that kind of bridge between the ideals of Batman and living a coherent, productive life in society. That's my take of his character, anyway.

So, more to the point, I understand why someone wouldn't like this character design. I also really dislike the shaved head, but I think they covered it with the hood because they may have realized it was out of place. I think there's too much red in the costume; it needs way more green (regardless of any Christmas connotations). Kind of defeats the purpose of having the Red Robin, if the Robin costume itself is already red up the ass.

However, I do think that this side of Robin has a place, and he is well utilized in Arkham City. I imagine the lighter side of Robin still being a part of his character, but now he's grown up a bit and is just trying to get the job done. I gather this from the way the thugs talk to Robin; they patronize him a bit more than Batman and, to me, act as if he was never as much of a threat.
