Spiderman fans on the other hand, base their arguments on sheer ability and powers. Spiderman outclasses, by a very large margin, Batman in every physical way. Spiderman's strength, speed, and durability alone is enough to win a random street fight with Batman. Then we have to think about things like his spider sense or webbing and it's practically in the bag for him. On paper, Spiderman "should" win this fight. You can make up a million reasons for Batman winning this fight; but he'll always be an underdog.I don't care if you have a comic scan where Spiderman squeezes a balloon with intent to kill and can't do it.
"It is assumed that each contestant will fight to his/her best ability, but still within the character's personality, unless specified otherwise. That means they will use any powers at their disposal. For example, even though The Flash doesn't clock each of his own opponents in the first picosecond in his own comic, it is assumed that is a viable tactic on this board since it is a proven fact that he possesses that level of speed.
It is also assumed that the characters fight at their optimum levels of ability - not explicitly weakened or unusually powered up for those who have variable power levels."
And where is says using all powers at their disposal i'm assuming they don't mean Batman carrying around every single gadget, batboat/copter/tank or whatever he's ever created. Just the things he would normally lug around.
That is from the forum rules. It is a proven fact that Spiderman can lift 20,000+ pounds and a punch from Spiderman would make Batman's melon explode. However, it is not in Spiderman's character to kill; so he will be holding back in his fight against Batman. And even when holding back, he "should" still hand Batman his ass.
Typical Batman fan counter-argument, "No seriously, man Batman could do three backflips bounce of a wall simotaneously throwing a batarang and three gas grenades while creating a device that will nullify Spiderman's wall crawling abilities and storing his chi for a punch that could make God cry."
See? That's a scenario. You can't prove that any of the things Batman does will land. But you can make up a scenario where they do. Based on sheer power and ability alone, I give this one easily to Spiderman. If I were to be writing a comic, i'd make it a close fight that gets interrupted by some super baddie who Spiderman and Batman have to team up against. If I were trying to be realistic knowing eachother's power levels? I'd draw one panel of Spiderman caving Batman's face in with one punch.
