They cant take hulk! Oh God this is Funny! The TMNT beat hulk? HA! And wolverine will kill them, He is extremely skilled, just as much as cap, and i dont see them doin squat to him. Of cource they could hurt him but i think hill kill them in the first few min.
Seriously, TMNT are good MAs and all, but they are fine limits as to who they can and cannot beat. Wolverine with his superior fighting skill, healing factor, and adamantium-laced claws will rend them to pieces, Carnage with all of Spider-Man's powers at much higher levels and the ability to create weapons out of his tendrils would allow him to decimate the turtles even all at once, Hulk is just plain too strong and too powerful for them, and Spidey himself would be the weak link but I'd bet he could take a few wins. But seriously, the threadmaker has been really making some dumb fights that are more like spamfests than well thought out fights.
See the big difference between Wolvie and the TMNT fighting wise. Is taht the TMNT actually use their skills, all Wolvie does is lunge at people while forgetting he's a martial arts master. So you can't seriously put wolverine above them in fighting skill. When he is depicted as nothing more than a lunger and brawler. His other abilities puts him over them though, but based on TMNT showings I wouldn't put it over them to find away to disable him.
Also if you can't conceivably see how the TMNT beat everybody except hulk and Wolvie. Then your most likely just not a fan and have not seen them take on things of greater power. Which would make characters like Doc Oc and Green Goblin a joke. I just find it comical when people bring in non Marvel or DC characters to battles. All the comic fanboys come out in droves to say curbstomp without any basis.
Well, most people read either Marvel or DC with characters that have way more feats than TMNT/odd comic characters and this is a "comic book forum" after all.
