Well, the gadgets used by Batman (to the extent of my knowledge) are all inspired by actual gadgets. They might be a little exaggerated, but with the recent progress in science and technology, I don't see why they couldn't exist. (albeit if they're out in the market, they're bound to be pretty damn expensive!) So keep your hopes up and train as hard as you can. Cause when one day you actually do get a hold of those gadgets, I'm sure you could save the rest of the world. Best of luck dude!
