Batman could beat Spiderman in a fight.

Alrighty then. First to elaborate the list:Master of disguiseI doubt that. Batman has a full body suit, voice distortion device and an electric shock device on his mask, so that anybody who touches it would get a shock. So yeah, maybe a grilled 4th grader could figure it out. Also in public Bruce acts like a shameless douchebag just to throw everybody off the hook.But that wasn't even what I meant. I meant actual disguises. Often when Batman has to retrieve information about gangs and their whereabouts, he disguises himself as a mobster. He has various alter-ego's like Matches Malone, Thomas Quigly, Detective Hawke, Lester Krutz and many more.Now off to the arguments.Batman's got dirt on everyoneGotham city is very similar to New York with its tall buildings, so Batman is familiar as well. About the gliding, you're partially right, though Batman does have a pneumatic system in his boots giving him somewhat of a jetpack (not entirely though, but he can build up quite some speed).You're also forgetting Batman is a master tactician. Of course he knows he's in disadvantage if he went straight to him. There are many villains of his who are better in combat than Batman (like mr. Freeze), but he has defeated him despite.Batman is a billionareOkay, let's assume Spiderman does have organic webshooters. How strong the web is, it's still made of silk fibers, which can be easily destroyed using an acid-like substance. As for the Spider-sense, that's not flawless as well. Sure Spiderman could dodge the gas, but maybe Batman could plug it on himself, making Spiderman unable to approach him. Also his senses are immume for symbiotes. All Batman would have to do was collect a little symbiote-stuff, reproduce it and he has a weapon. If even that wouldn't work, Iron Man once made a device that sent off false Spidey Sense waves confusing the sh*t out of him. There are tons of things to disrupt his Sense. And without Spiderman's senses, Batman could defeat him easily since, Spiderman was never trained in combat as Batman was.Batman is a predatorNo, with predator I didn't mean someone who can escape. With predator I mean making good use of your training as a ninja and waiting in the dark until your prey is distracted, then grab him when he doesn't notice. Something which Spiderman could never do since his suit is effin' red and blue.As for the night vision. I've looked into it and it were actually goggles, and Spidey used it once. And it was a thermal vision goggle which can easily be bypassed by for example not moving or cooling your suit down.Also Batman can bend metal with his bare hands so I guess he can also struggle himself loose from a mere spiderweb, especially in combination with his anti-spidey-cum-acid.Batman can beat anyoneIf Batman had a beard, he could even beat Chuck Norris, guaranteed.Yes Bane broke his back, but he still recovered, didn't he? Azrael took his place in that time but Batman subdued him because he was too violent.Just like Spiderman has been defeated many times and even Mary Jane had been killed several times due too Spidey's swagger. Off to your case.Batman relies on his equipmentThat is like saying without Spidey's spider powers, he couldn't win either. Batman has them, so he makes use of them. Also if you took away his equipment, he would still be a multi-millionare, ninja, master tactician, master of disguise, master of interrogation and police techniques and combatant. Also one of his biggest powers is his great will power, with that he can achieve about everything he sets his mind to.Spiderman's web puts Batman at a disadvantageYes, it's his ultimate if not only weapon. That means if Batman found a way to destroy it, Spidey would lose. I've already told various ways to destroy that web of his. That's the difference between Spidey and Batman. Spiderman keeps clinging to his superpowers, making him predictable, while Batman keeps improving his tactics and adjusting them to his enemy, making him unpredictable and hard to beat.Moral choiceThis is what you understand under "defeating". Kill? No. KO? Likely. You said yourself Batman has been beaten numerous times, but never really killed (unless you count the trips to the lazarus pit). But there are ways to subdueing Spiderman and letting him live. Spiderman has killed several times, which he mostly did out of anger. This shows Batman is mentally more stable than Spiderman.So if we talk about killing, then it would be an infinite fight since they would never kill each other. But if we're talking about KO'ing, then there's no problem.Good luck to you too.
