Well, all superheroes have shitty beginnings. All of them.
I honestly think it's a good idea. You know, to have a superhero do the work that cops won't/can't do. Good idea, bad execution. Think about it: If we had someone like Batman, an amazing kickass man wearing a suit, someone who's cannot be caught and someone who can take down an entire army by himself no matter what kind of weapon they're carrying, it would be awesome! Like comics teach us: They're a symbol of hope for people.
But this guy? Oh, man. I understand what he's trying to do. Looking beyond the dildo costume, I can see a guy who probably just want to make things right. Yes, he could be a little dense and he might just be thinking he lives in some sort of alternate reality. Or he could be perfectly normal and doing it for fame. Whatever it is, his intentions are good. If you ask me, if the guy is trying to counter violence, I could care less if he's doing it in order to gain popularity.
If anything, I would advice this guy to pick his fights. Like someone said, there was no princess to rescue in here. I'm not saying something like "Oh, only help pretty people" or "Random violence? Pssh, that's for pussies. I need a real challenge!". No, no. I mean that, in that case, it was a lost cause anyway. They were all obviously drunk and the women, who I assumed were the victims to being with, didn't want his help, either because they were freaked out by the fetish costume or they were too drunk or whatever. So you know what? Walk away. Not even worth it. They're drunk, let them kill each other if they want to. You see someone breaking and entering a store? Yes, do something by all means! You see a thug steal a woman's purse? Go get him, tiger! But this? So not worth it.
Still, like I said, good idea, horrible execution. Good try, though.
