True Hope

The Blue lantern Corp from DC  (yes flexing my geek muscle lol)

green lanterns run off Will

Blue power rings run off Hope

And last I checked there were like six of them in the universe, right?

Mind you, I only get the TPBs and so am only read up to the first collection of Brightest Day. If they find the planet Hopulon-8 in the next part of the story arc, I will stand corrected.

Superman is probably just as good an example.  In fact, in the Dresdenverse, I'd be tempted to say that Superman's symbol might qualify.  He's one of the top-five most recognized fictional characters on the planet, and I think hope in general is strongly tied to the character.  Belief is power in DV, right?

If you don't have Superman, then President Obama would probably work too, but he's harder to get a hold of.

I'd agree with a previous poster.  True Hope is, at the least, one who had a chance to fall to despair and resisted.

Another option, instead of or in addition to the above, is one who spreads that hope - who has helped another resist despair.  That'd fit the outwardly-oriented type if emotion I recall the book favoring.
