he didn't that's news to me....It made zero sense for Robin to beat Slade at all ever. In RPG terms it's like having a level 20 character fight a level 50... you shouldn't expect to win. But Robin does. Also Robin has no powers and Slade is a genuine meta-human. Low tier mind you, but he's stronger than an ordinary person will ever be, and heals faster. Batman has trouble beating him because of that.Teen Titans Robin could fight Slade evenly 1 on 1 even when Slade could beat the other 3 SUPERPOWERED members all by himself. But sure, a teenage boy with no powers is a match for him. Robin could also be a moody jerk on the show but he never gets shit for it. Bruce not acting like Mister Rogers makes him a monster tho.
See... having "negative" character traits is only a flaw if those traits actually influence the way you interact with things and people. If all people do is tell you you're crazy... it's not a flaw, it's a quirk. Batman's interesting character traits are more a quirk than a flaw... despite the fact that they really should be problems.honestly, I like the idea of Batman. But i personally feel that there are at present more stories where he's written badly than written well.Also, if Bruce is such a horrible person with so many negative character traits, how the hell is he a Mary Sue? Wouldn't a Mary Sue be someone with no flaws? You could call him one if he acted like Ned Flanders but he doesn't. He has flaws that get brought up by other characters all the damn time. "I don't like this character so I hate when they have impressive feats" isn't the same thing as said character being a Mary Sue.
For example: the "no kill rule". Batman is famous for his idea that if he kills people he doesn't deserve to be called a hero. But... he's fine with beating people half to death and leaving them with no medical attention. Oh and the no kill rule apparently only applies to humans. Aliens? Poison Ivy's pod-people? Even if they're named characters there's a good chance you'll never see them again.
For example: in New Batman Adventures episode "Chemistry"; Bruce Wayne meets a woman named Susan Maguire and marries her.... then later kills her as Batman after he finds out she's one of Poison Ivy's pod-people. They even put in a scene where he tosses his wedding ring into the ocean afterwards... lol wut? It's a weird episode because Batman goes to a lot of work to save people... but only humans. Heck he doesn't even save Poison Ivy... he leaves her on a burning hulk of a ship as it sinks in the deep ocean. Yes.. Poison Ivy is the reason the ship was a burning hulk. But... he leaves her to die.
I think part of it is a desire to make it look unique. the gargoyle architecture makes it stand out from other locations in the comics.
