/r/Whowouldwin... Assuming you really want to find likeminded people who care about these scenarios, that subreddit will do you tons better than this site.

I'm not dissing your question, nor am I stating you can't ask it, I'm only offering that as an alternative in case you want to see this get more reception, since this site is for the most part dead, and those who do visit probably would care very little about this fictional scenario.

Cynicism aside, I believe the Incredibles would win.

Reason one they have more people. I tend to place my money on numbers when I don't know individual strengths.

Reason two they have Jack-jack. The little baby was shown to have some crazy morphing powers that allowed him to be pretty much whatever he wanted. In the movie (I'll say first one, since no sequel exists.... yet) he was shown to be very powerful despite not even being able to walk or talk yet, so I believe when he is capable of doing that he'll be a true force to be reckoned with.

Now for specifics, you have Frozone, a guy with the ability to freeze things. That's an instant advantage over Mr. Fantastic... if he can touch him that is. You have Dash, a kid that for all intents and purposes is the flash (or in the spirit of Marvel, is Quicksilver). So Dash and Frozone tag team Mr. Fantasitc, the brains of their whole suit, by having Dash literally grab him, and stretch him thin, then Frozone comes in to freeze his whole body, or enough of it to incapacitate him.

Then we have the battle between The Human torch and who ever wants to have a go. Obviously it'll be Frozone again. They'll waste their energy blasting equal power shots at one another, from equal angles, until Dash comes to the rescue catching an inflamed Human torch off guard, while he's resting on the ground. Surrounding him in a wind tunnel that deprives him of oxygen, and thus his power, only long enough to leave him unconscious.

Now we have an invisible woman, vs an invisible girl. Not much either of them can do to each other, except that The Invisible Woman is actually physically stronger than Violet, and she's a super scientist so she's way smarter than her. Could draw, but will later be taken care of by the rest of the team.

All the while the heavy hitters, Mr. Incredible and The Thing, are having a flexing contest.

Because the incredibles are just awesome.

Wish they made a sequel.

the incredibles are incredible :)
