I really absolutely love Robin's Golden Age look in the first image. It's the little things like this that, the attention to detail (well, and devotion to utter insanity) that make the show so great. I really don't know if he can work all that well in this show though. Robin is supposed to be Batman's partner, but the format of the show demands a different guest star every episode. So.. he's Batman's closest ally, except for all the other times when he's not, which is basically all the time. He'd pretty much have to either join the Teen Titans or become Nightwing at the end of the episode.
Great, now I'm arguing about the internal logic of an incredibly goofy cartoon for kids. Please, someone call an ambulance, I have obviously caught the Nerd Flu.
