Morkus from Orkus
She was said to be the greatest with the possible exception of Feanor. They were on par. Fingolfin, though, had no chance of winning. Wounding Morgoth 8 times was about as good as it was going to get.I am not sure this is an example of "not Galadriel" in my mind. Because she's possibly the greatest elf after Fëanor and possibly Luthien. If Fingolfin can ride to Angband and challenge Morgoth to a single duel (and expect to have a chance of winning) after frightening all of Angband's host, an "even superior elf" might be able to be that badass. It's not explicitely within their abilities, but not "out of character".
That said, none of them could swim an entire ocean, which is why she, Feanor, Fingolfin and all the rest either had to take a ship, or walk the Helcaraxe.
I agree.I'd be easier if the she was a totally new character because of her reckless behaviour -- that fits better the other noldor princes of her immediate family.
Edit: Didn't see the mod post until after I posted this. I won't post again in this part of the discussion.
