[Frodo Baggins]

Now here is an interesting topic. a bit off topic, but there were some men, such as Beren and Turin, that were, or seemed to be, physically stronger than the "Average" Elf.

As for the Ulairi, they work with Sauron's power mostly. Truthfully I'm not sure an average, everyday elf could take them on. Remember how they all shoved their fingers in thear ears when Gandalf spoke the black speech.

Here's an intersting key. It says that Morgoth and Sauron feard Varda above all the other Valar. Aragorn says to Frodo after the attack upon Amon Sul, "More deady to him (the witch-king) was the name of Elbereth." The Ringwraiths got really scared when they heard that name.

Aragorn didn't really defeat the Wraiths, he just temporarily chased them off. Still, the Hobbits themselves attempted to fight them, Frodo even stabbed one of them, so apparently even Little Ones can put up a fight. If not for very long.

Now as for elves. Perhaps the average elf could put up a bit of a fight, just as hobbits and rangers/exiled kings. Gandalf said there were few in Rivendell who could ride against the nine. Glorfindel is one. He saw the two trees, and the light of Aman is in his face. Also, he had encountered the Witch-King before in the wars with Angmar earlier in the Third Age. It was there that the Ulairi learned that Glorfindel was scary and not to be messed with. He could very likely mop the floor with at least one or two.

Galadriel as well. She saw the Trees before they were destroyed and I think lived partly in Aman (at least in her thoughts) while in MIddle Earth. And she is a fighter, they didnt call her Man-maiden for nothing.

Gandalf, Olorin, Maia of Lorien. In a sense he is equal to Sauron and above the Ulairi on the power scale. He drove the Witch-King from the gate of Minas Tirith. We don't really know what he did on Weathertop, but I think all nine would likely be too much even for him.

Forgive me but I'm not sure Elrond would be able to take on more than one at a time. Yes he does have Vilya but I'm not sure that would be much help. Also, he was born in Middle-earth, after the destruction of the trees. I doubt he would be in both realms at once, but he may. But then, Eowyn didn thave anything but her sword, her wrath, and a loophole on a porphecy. So who knows?
