It may not be one punch, but Namor beats her easily though. If rouge grabs him, the fight may end early unless Namor gets water to bring him back to. If not, she wins. But I still say Namor beats her fairly easy.
She still is a great character AND itīs much more interesting to watch how she handles upcoming problems, now that "superpunch in the face" does not work anymore!!!
Namor and Classic-Rogue have basically the same powers, though he is stronger and she is faster. So i guess itīs: "Will he get a boost from water first or will she get a boost from him?"
Both characters have the potential to knock out one another. Since I find, that the leeching powers give Rogue a little advantage, i go with her.
