Relative Powers

[drigel]

You're assuming here that Huan is a Maia, while there's no text supporting that idea, as far as I know.

here's another rub to the list that I havent thought until now - the power of fate or doom (or prophecy), as it incorporates with the characters, examples:

WK was not going to be slain by any "man" - wouldnt that default him above at least all the human males? What about elvish males?

Huan -

.....and it was decreed that he should meet death, but not until he encountered the mightiest wolf that would ever walk the world.

so, regardless of the Maiar issue, a timeline to be considered - any entity having hostile actions towards Huan before the wolf encounter would be dealing not only with Huan, but also with the doom that was bound to to that hound dog.

After all, we seem to be judging a person's/thing's 'power' by its effect on the world/other people.

- remove The Ring

Or, if you include objects, then consider others - the Watchers, Orthanc, the Mirror of Galadriel, etc etc.
