They would lose against those two, but let Rogue in. Rogue would defeat Ms Marvel and Wonder Woman and then go on to kick the daylights out of the Hulks. She would look like a real freak after fighting them and where ever they fought would look like a battle from World War 3, but Rogue would win in the end.
Maybe but in the comics so far Rogue took Ms Marvel apart the first time before she had absorbed her and won. As for She Hulk, Rogue has bested She Hulk every single time they have faced off. It would have been nice to see how the writers would have handled the Dc vs Marvel cross over a few years ago if they had placed Rogue against Wonder Woman instead of Storm. And considering Storm defeated Wonder Woman, it did not say much for Wonder Woman. Really it is a moot point since outside of Ms Marvel and She Hulk, none of the writers have ever placed Rogue against any other powerful heroine. Granted Rogue has taken out the Avengers by herself before and all it would take is a touch to basically wipe out any of the DC heroines. (example, Rogue gets a touch of Wonder Woman, just enough to learn her fighting skills, Wonder Woman would then be finished. And if Rogue had touched Powergirl or Supergirl first, The entire island of Amazons would be finished within an hour or less.
Regardless of my or any other opinion, that is the great thing about comics, since they can never really happen, everyone can have it their own way.
That cross-over was decided by fan votes. Rogue took Ms Marvels powers by surprise, Ms Marvel isn't stupid to fall again to same trick. Due to WOnder Woman's super-speed and enhanced perception she would be able to see rogue moving in slow motion and lasso her before she can get close. If she hulk is aware of rogue's presences then one thunderclap would end her. Current Rogue doesn't have Ms Marvel's powers and she is as durable as base human. Wonder WOman has bested powergirl and supergirl before.
