I just went and looked at lizbee's page and discovered that she'd included TV, movie and comics characters, too. Well, then:

- The Fifth Doctor
- Mirth, and Sean Knight (but especially Mirth), from Matt Wagner's Mage: The Hero Discovered
- Jamie, from Truly, Madly, Deeply

And back on the literary side, I know who I forgot:

- Mr. Knightley, from Jane Austen's Emma

Duh, how could I have forgotten him?
