Let's check out what they can do.
Spider-Man
Wolverine
In overall fighting, we have seen that Spider-Man would have the upper hand. In an extended fight, Wolverine would eventually take the upper hand as Spider-Man wore down. As Wolverine mentioned to him during their fight in the 1987 issue 1 of Spider-Man versus Wolverine, the only way to really beat him would be to kill him. They were interrupted, so we did not see how it would end, but that is something Spider-Man would probably not be willing to do.
Wolverine, obviously:he's older, so he's a more experienced fighter, he can heal and he has indestructible metal as weapons, but also to protect his skeletal structure. Spiderman is maybe more agile, but his spider webs would have little affect on Wolverine.
Spider-man would beat Wolverine because he is faster than a speeding Goblin. He is also stronger than Venom and Carnage. Everybody but Zod, Jesus, Superman, and Hulk. He would rip Wolverine's heart out as he swings at his chest. And then rescue Mary Jane Watson.
It would depend on the circumstances of the fight. Spider-Man has superior agility and reflexes, while Wolverine has his adamantium claws and healing factor. In a straight-up fight, Wolverine's regenerative abilities may give him the edge over Spider-Man.
A fight between Iron Man, Spiderman and Wolverine would consist of Spiderman being knocked out right away, as his strength could not keep up. Iron Man would blast Wolverine over and over, but when he sees that Wolverine can not be killed, he would attempt to trap him instead. This would probably fail, as Wolverine would just tear the suit up with his claws.
Wolverine.
Batman would pwn spiderman wolverine is invincible so wolvie would slaughter batsy but it would take a long long long time
Wolverine. Not only is he able to heal all his wounds, he has claws. Friggen claws, man. Spiderman has cool powers, sure, but they're defensive-- his webs can't really be used as a weapon unless he shoots them into someone's mouth to suffocate them. Realistically speaking, of course, such a fight would never occur because Spiderman would take one look at Wolverine and realize that he cannot compare to this pinnacle of manhood.
Wolverine hands downnnn!
Spiderman shoots webs while Wolverine is practically invincible and has blades coming out of his knuckles... so it's pretty easy to guess the outcome.
wolfverine hands down :)
