Batman defeats Spiderman

Batman and Spider-Man are both among the most intelligent scientists of their respective worlds. They excel in gadgetry, with Spider-Man having the edge of improvisation because Batman relies on his wealth, while Peter Parker has always worked with limited supplies.Both are experienced crime fighters.Spider-Man is a meta-human with heightened strength and reflexes.Both are heroes.The two meet due to some strange convergence of their universes. This has happened in the comics, btw.http://marvel.wikia.com...http://toobusythinkingboutcomics.blogspot.de...And while OTHER heroes and superheroes tend to fight it out during their respective crossovers, those two are the best guys around and resolve their differences PEACEFULLY, gaining mutual respect and cooperating with each other. They shake hands in both issues, once to part and once to welcome each other back as friends.So, since the meeting has already happened TWICE and did not lead to a fight, there is no EVIDENCE to conclude from that Batman would EVER even ATTEMPT to beat Spider-Man.And since my opponent did NOT define any circumstances under which those two would not be partners, this imply never happens, and this debate is over.Batman would not defeat Spider-Man. He had two occasions to do so and didn't even try. All my opponent has in order to go against this would be his "geek" "knowledge", in other words: pure speculation. Set against what has already happened in the comics.Now, for another fact: http://en.wikipedia.org...Spider-Man has officially beaten Superman's clone Superboy, who is clearly superior in power to Batman.http://hero-envy.blogspot.de...Spider-Man has defeated foes like the virtually unstoppable Juggernaut.AND, specifically, Spider-Man has repeatedly bested the Green Goblin, who is basically an evil Batman with the addition of a lethal glider and no qualms about inadvertently killing people: a rich, genius billionaire with an arsenal of gadgets, including smoke grenades, throwing stars not unlike the famous batarangs, and who is additionally stronger than any human due to the Green Goblin formula, a variation of the super soldier serum that gave Captain America his powers.All this is fact.Batman, quite to the contrary, has only stopped villains who are superior to Spider-Man in only ONE aspect at a time. Either someone even more intelligent, but lacking Spider-Man's strength and particularly the Spider-sense that warns him of any danger. Or someone stronger, but then lacking the brilliant mind.If my opponent wants to come up with his battles against Superman: Kryptonite always played a crucial part in those, and Spider-Man has no such weakness.Spider-Man single-handedly defeated all of the Fantastic Four without preparation, when he was just a kid:http://marvel.wikia.com...So, he effortlessly beat:- the elaborate building security system- the most brilliant scientist of that world- the second strongest being of that world- an invisible woman who can project force fields- a metahuman who can project really hot flames and flywithout breaking a sweat, just to make an impression - so not even trying to harm anyone. And that was IN their lab, where Reed Richards has all his tech.Even Batman cannot be better than a team of the finest heroes in their own headquarters.So, even in a sparring match, Spider-Man wins.
