It's not immortality for the Norse pantheon to my knowledge. It's just an extremely long-lived life.
And Herc wins.
I actually think I could find a scan from Infinity Crusade where Herc one-shots her and then drags her back to the group by her hair if I absolutely needed to (but I'd rather not).
wasn't that one of her first appearances also? if she fights to the best of her abilities (instead of the crap she normally does) then she can win a few bouts like 3 or 4 wins out of 10.
Breaks the forcefield and BFR's Herc in an impressive display of strength....but I'd honestly put him around the same level as Herc based on what I've seen of him (which, admittedly, isn't much).
Herc would just one-shot her again. This is a guy who regularly slugs it out with Hulk and Thor. Saying a Class 50 X-man is gonna beat him is ludicrous.
Herc. hit Rogue with a cheap shot. Rogue does not have to slug it out with him to win, she will loose if she does that. Her durabilty and strength is enough to get in close and touch him.

Just because he got a cheap shot does by no means mean that he can't take her, or clobber her beyond all means. This is a guy who was in an arm wrestling match that nearly shook the planet out of orbit, and didn't seem strained by it.
Even if she touched him, he'd grab her wrist and break it. This contest isn't even close.
