[DC] What is Batman?

Hi. I'm a new member of the Justice League. My power lends itself to support, so I've been working with them quite a bit. You naturally learn about your teammates as you go — some of them love to announce their powers to everyone with fancy names; others just fill the new guy in quietly before a mission. You absorb all you can to help you work better together.

My question is about Batman. I haven't spoken to him directly, but I've been on missions where he's been involved, and I've gotten a good look at what he can do. People who should know have told me in no uncertain terms that he has no powers.

OK, Batman is *clearly* not human. People train all their lives to be fast or strong... he's faster than literally any human can possibly ever be without powers, stronger than literally any human being can ever be without powers. You can train your muscles, but how do you train to dodge a bullet? Chemical reactions in the eyes and nerves just don't happen fast enough; it's not about steroids or hard work or winning the genetic lottery.

I've been told things like, "His superpower is that he doesn't know how to quit," and I trust the people who told me, but determination alone doesn't let you hit hard enough to harm things that no human has any business harming. Determination gets you a broken hand if you try that. He's physically not human, in so many different dimensions at once. It's not at all subtle when you get a look at him in daylight. And no one will tell me what's really going on.

What *is* he?

Batman is Human.  
There are almost 8 billions of humans. And statistically speaking, one of them is THE BEST HUMAN. Ubermensch you can say. That is the Batman. A Human that have almost unlimited potential realize.  
IF you asking how anybody can dodge bullet that is coming ad them, than nobody can do it. But you can see were gun is pointing, and start moving out of bullet way before finger pulls the trigger.   
Batman is human. But ALL his stats are in top. Than add insane training, and one of the most advanced technologies that earth can offer, an you have Batman.
