I t depends on the Turtles as a team, I guess. If they fight defensively, covering each other, all they need is to get one lucky strike. Or one of them just has to slow him down for long enough.
But I don't know - I haven't read any Turtles comics, I've only seen their cartoons and movies.
Basically, I think Spider-Man can win, but only if he fights strategically, if he plans the battle, if he can strike from a distance and break up their formation, by throwing them with stuff, for instance, like cars...
But I don't count Spider-Man as one of the better strategists around, he's too emotional and impulsive.
It's hard to judge without ever having read Tutles comics, but if they are disciplined enough I think they might put Spidey on the defensive...
I am still very undecided!
Nice match-up, Capt - taking the webs away was a good idea!
