I think Iceman and Storm alone can handle 6 and 7. And IMO 8, 9 & 10 shouldnt be too much of a problem with Spiderman too, not to mention Wolverine and Batman.
I think the best thing for me to do here is first go over the teams here and why I chose them, so everyone will have a better idea of this gauntlet.
Lets begin with the team running the gauntlet. I must emphasize that this is the MOVIE VERSION of the characters, not their comic counterparts. It's also important to know which movies they're from.
Spiderman- The all around best fighter from the team. The one everyone has to watch out for.
Batman- This is the one from Batman Begins. He's the best skilled fighter in the team and has nifty weapons. But his equipment is the least advanced compared to the other Batmans.
Wolverine- It's the X-men members that people seem to have the most ignorance about here. This Wolvie is the one from X-1, not the T-1000 Wolverine from X-3. His healing is alot slower and he's able to get knocked out cold with a log to the face. On top of that his fighting skills aren't very good. He does however is still able to withstand the most punishment in the team.
Storm- Like Wolverine, this is the Storm from X-1. I'm skeptical a woman who has trouble taking on Toad even with Cyclops's and Jean's help will be able to clear 6 and 7 on her own. Her fight skills are probably zero. Her wind and flight powers don't appear too impressive here, and she can't shoot lightning out of her hands yet. One good thing is that she can still make lightning strike down. Though takes her some time to do so.
Iceman- This is Bobby from X-2. I added him here for extra support but he's the least effective member in the team in my eyes. He can't ice up yet and not only is his fight skills probably zero too, but doesn't have any fight experience either. What did he even do in X-2 besides run away from Strykers' men?
Now for the opposing team. I'll omit team 3 because every knows they're tough, and team 2 just because they'll low on the list.
Nomak- Watch his fight with Blade (sorry I'm new, so I can't post links yet) You try and tell me which members of the team would be able to withstand a beating like that with maybe the exception of Parker and Logan. Not to mention getting neck bite and drained of blood will slow down team members quite effectively. His strength and speed exceeds that of everyone except Parker. Should I also remind you guys that reapers and vampires have fast healing? I might be thinking of ommiting the infection part because having to fight team members who been turned to reapers and vampires is a bit cheap.
Selene at end of UE and Venom- For anyone who hadn't seen Underworld Evolution, but saw the first one, remember Michael when he became the hybrid? And Remember that elder that was shown drinking werewolf blood and will become a hybrid at the end? Well his name is Marcus, and by the end of the second film this is how the three characters rank in hand to hand combat alone.
Selene > Marcus > Michael
Now add the weapons she'll carry and you get a idea how tough an enemy she'll be. Not to mention once the team members go against guys with guns it becomes more difficult. Spiderman, Batman and Wolverine might find a way around it, but it's the other two that will have problems against firearms. Storm and Iceman aren't bulletproof, nor can they dodge bullets. Add the 3 reaper/vampire advantages (I think she's even stronger than Nomak) and you have an idea what she can do. I hadn't watch Spiderman 3 yet (I will this Sunday) to know exactly what are Venom's capabilities. Though I heard he's pretty tough for a beginner on the threads about him.
Blade and Hellboy- Blade by the 3rd film pwned everyone he fought, even the powerful Drake didn't put up much of a fight. He's basically about on par with UE Selene in fighting. Don't forget about the 3 reaper/vampire advantages. Now Hellboy may not be as skilled as his teammate in fighting or as fast, but his higher durability and strength makes up for it. He may not have fast healing, but having a body that can't get burnt comes in handy when you have alot of firery/explosive weaponry. Unlike the previous team, both of these guys have weapons at their disposal, and they're quite skilled with them too.
T-Rex and 2 velociraptors- Okay now it begins to become a new ball game. The team will have to lay alot more damage than previously before and there's a good chance anyone of them can get one hit KO'd from now on. Now you people are probably thinking Wolverine's adamantium will protect him right? Will his adamantium are laced over his bones, but not his joints. Meaning if they grabbed onto a body part and begins pulling, will bones will stay but his joints won't. Wolverine going to lose a body part. Are you people aware that animals are naturally more stronger, durable and resilient than humans? It takes a lot of shots from high powered rifles to take down a bear, can you imagine what's required to take down a T-rex? I should also mention this T-rex doesn't have the silly motion vision that was added to the film. Don't let the size fool you, T-rexes are very fast. Remember how in the first film the T-rex almost caught the jeep, but was slowed down by the fallen tree? Now velociraptors aren't stupid. According to the film they're smarter than any living animal except humans and quite possibly faster than cheetas. They know great tactics like how when they sneak attacked the humans in the tall grass in the second film, and when one of them distracted a hunter while the other went around and killed him in the first film. Only this time they have a T-rex to keep the others distracted.
King Kong (2005)- Fought 3 T-rexes at the same time and won, need I say more. Just like rex, Kong is also very fast. Remember how it got ahead of Adrien Brody in the taxi? The team's best offensive against these two prehistoric beast is to use Storm's lightning strikes, and that's off course assuming she doesn't miss.
