How about a contest along the lines of the esteemed
Middle Earth popularity Cup ?
===========================================
Voting rules:
Voting could be allowed to continue for approx. 24 hours. If there's a tie then the earlier vote getting to the tie would be the tiebreaker.
===========================================
I'd suggest considerations for voting be along the lines of a beauty
pageant. WHAT! Well, I mean to consider various aspects of the characters.
For example, when I used to watch some of it, the Miss America pageant
had talent (but then so does Miss Alaska- Sarah Palin plays a flute

),
swimsuit competition, and at one time questions. So you might
consider
a)fighting prowess b)"personality" c)survival intelligence (think
Odysseus) while voting. Thus, it's not INCONCEIVABLE (assuming that word means what you think) to choose, say, Bert over the Watcher in the Water.
============================================
I'll wait a while to see if there are suggestions to add/replace
the candidates below. Btw, Ungoliant and balrogs weren't included
since it seemed they might be too puisant (but I'm open to
additions/changes).
