Could Eru create a ring so corrupting that even He could not resist it?
Pervy hobbit fancier.
As for other characters carrying the Ring to Mount Doom, what about some of Moorcock’s Eternal Champion aspects? Erekosë and Elric are both used to dealing with extreme, prolonged torment, in a heroically masochistic kind-of-way.
Wow, skip a thread for a few days and miss where it goes.
First, I need to get a couple of overused SDMB cliches out of the way:
Batman (if he’s prepared)
Jack Bauer (or MILLIONS OF PEOPLE WILL DIE!)
How about Amelia from Slayers? Granted, Lina would try to steal it constantly, but I’ll take Lina and Gourrey against the Witch King of Angmar any day.
Captain Marvel probably could handle it.
Serge from Tim Dorsey’s books, or Skink from Carl Hiassen’s books. Both of those loons make Gollum seem well-adjusted…and they start out that way!
Sir Galahad.
Thanks, I guess as Anaamika says, I need to finally see the original.
Cerowyn: Elric would be tempted too easily to use the ring and thus would he fail.
BlackKnight: Nope, unless it was part of his plan all along. 
roger thornhill: Interesting but what were you replying to, that seems to be out of nowhere.
asterion In the End Kyle & Cartman would wrestle for it and it would roll on the ground towards Kenny who would of course fall into Mt. Doom. “Oh my Eru Ilúvatar! They killed Kenny!”
Civil Guy: All the aspiring wizards are a little power hungry and a little too attuned to power to resist, junior Wizards are probably among the worst candidates.
Fabulous Creature I’ll concede that Mirror rorriM doesn’t prove anything, I just think overall Spock broke down with emotion often enough not to be a good candidate to carry the ring. He might wish to investigate also.
Qadgop the Mercotan: Don’t worry we’ll supply you with plenty of Lembas and Cheese and provide you escort of course. I’ll travel as far as the Prancing Pony, what do you mean that’s the wrong direction?

I see that I must needs speak no longer in riddles, as the time is nigh, and darkness threatens us on every side. In answer to the question “Who else could have carried the ring?”, there is, my friend, one answer and one answer only. Not more or less than that. Only the author himself, St Tollers of Worcestershire-where-it-joins-with-Warwickshire in what is now - oh! abomination - called the West Midlands (or was at least until the most recent of those confounded boundary changes so beloved of motor car driving ignoramuses who want to build roads everywhere). Where was I? Oh, yes, only St Tollers himself can bear that terrible burden, possessed as he is of the wisdom of Gandalf, the fortitude of Frodo, the fecundity of Aragorn, and the pulchritude of Arwen–and, might I add, while I have as it were the stage, the tweeness of Tom Bombadil admixed with the excruciating singing of Goldberry.
Ahh, so you don’t like Tolkien much do you?
Tollers may have been able to carry the Ring but the pulchritude of Arwen belonged to his wife according to the Professor.
Give it to Thomas Covenant. He’d be more than happy to get rid of it.
Well, yes and no, old chap. She was indeed beauteous to behold, but the outpourings of her mouth were rather akin to a washer-woman. And she even liked that Joy Davidman creature who took my Jack away. So, I retired into my garage and wrote, and dreamt, and played cards, dreaming of my ideal female, Arwen crossed with Eowen. Perfection!!
Ok, I assume Joy was the American Marxist Poet Divorcée that married Lewis, your favorite author and Inkling. You misspelled Eowyn who was not Tolkien’s ideal. She was to represent the old Norse Tradition of a Shield Maiden. Arwen and Luthien or Galadriel the mysterious Elven Queen were his ideals.
He did a lot of his writing in a stuffy old study from what I have gathered. One assistant described the smell of Pipe Smoke as a permanent feature.
Did you by any chance eat some funny Mushrooms today or smoke some exotic Pipeweed?

What do I win?
The problem is going to be that the One Ring will its wielder what he or she desires – twisted, to be as evil as possible.
For someone like Spock, it’s going to give him the non-emotional logic he wants to achieve. He’d end up a particularly brutal and compassionless Dark Lord.
… plus, we’d have to endure some hack writing a crossover novel named Dark Spock, and then I’d have to toss someone into Mt. Doom.
I’m thinking that the only option is someone who’s not-quite-human enough to have any desires for the One Ring to hook on to. Maybe Aslan.
Either that, or you need a character who’s just going to succeed in overcoming the One Ring by plot immunity, writer fiat, and innate Mary Sue-ness. Like Harry Potter. Or Drizzt do’Urden. Or Frodo.
I think we have to limit potential ring-bearers to Fictional characters. Therefore Dear Professor JRRT is out. Otherwise we’d be arguing if Schweitzer, Gandhi, Jesus or Buddha, etc, could do it.
Personally, I think Frodo is a unique hero in literature. uniquely qualified to bear the ring. (Linus nonwithstanding, and Taran Wanderer is a pretty good candidate; any nominations from The Dark is Rising series, Wonderland, or Oz?)
(and the characters from Wind in the Willows or the Hundred Acre Wood would be So Out of Luck if Sauron showed up.)
But then, so would a hobbit. The whole ploy, no matter who carried the damned thing, depended crucially on Sauron not showing up.
How would Paul Atriedes have fared, do you think? He didn’t want power, but it seemed to accrue to him despite his wishes anyway. I’m thinking that he’d either be plot-fiat immune, or the worst of the lot, but I can’t figure out which.
I’m leaning toward “worst of the lot”. He already had substantial power and had been conditioned to be fairly ruthless, although he had a softer side. He would have fallen, not through doing what he thought was right, but through doing what he believed was necessary.
The Oz characters for the most part either had Gandalf’s problem–they would be tempted to use the Ring to do good, only to find its power twisting in their hands–or had crucial insecurities the Ring could play upon. In this context, Dorothy’s character has more parallels with Sam’s than with Frodo’s; she would likely have remained uncorrupted longer than the others, but her desire to return home would be a weak point. Even if she managed to resist the Ring, I can’t picture her completing the journey.
I considered briefly the idea that some of the Kendar in P.C. Hodgell’s Kencyrath novels might be able to handle it if they were ordered to do so. There’s no question of them being fit for the journey–they could teach Aragorn a thing or two about stamina–and they were shaped by their god to be followers. Most of them seem to want nothing more than an honorable master and a place to call home (even if they never get to see it); there’s no indication that they have any inclination to seek personal power. Then I realized that it would mean putting the Ring in the hands of someone who could be compelled to hand it over to his lord…and I can’t imagine anything but utter, multiverse-wide disaster coming from that. Even at their best, the Highborn are not what you’d call “stable”. Jame leaves death and ruin in her wake even when she isn’t carrying any powerful, deadly artifacts…and she’s the heroine.
A Known Space Protector might be able to do it, if it knew what it was dealing with and either had it’s bloodline in the ME or adopted the local humans as it’s charge. It would know that the Ring is inherently malignant and uncontrollable, it would be unable to delude itself into thinking otherwise, and it’s compulsive nature would override any temptations the Ring tried.
OTOH they can be mistaken; if it didn’t believe it was uncontrollable, it would try to use the Ring, and a “Dark Protector” would be far more dangerous than poor old Sauron.
It’s phenomenal, if you can ignore the prolonged staring scenes. But I loved every minute of it.
I think maybe the Shrike (aka “The Lord of Pain”) could have done it.
Shrike vs. Balrog would have been pretty cool, too.
And if anyone besides Eowyn and Merry could have cleaved the spell which bound the Witch-King of Angmar’s undead flesh, I bet a cyborg warrior construct put together by the supreme being and endowed with time-shifting abilities would have been a good candidate.
I guess that’d be one way to put the Fellowship together. “Come with me if you want to live.”
I dunno who Shrike is, but this reminds me of two more -
Jebu, from Shike, might have been able to do it. He loved that girl but she was a two-timing power-mad little bitch anyway. 
What about The Nameless One, at the end of his odyssey? I dunno, he might have fallen victim to the power madness again. But at the end he was pretty devoid of desire.
Sorry, the Shrike is from Dan Simmons’ Hyperion and Endymion novels. Definitely a better class of cyborg than the Terminator. I always liked the concept of the Shrike’s “Tree of Pain”.
