I love so many characters, Iago from Othello, the Fool from King Lear. There is Gollum from Lord of the Rings, Sirius from Harry Potter. Damin Wolfblade from the Demonchild triology and Dirk from Second Sons trilogy, both by Jennifer Fallon. Dide and Asrohc from Kate Forsyth and Temeraire from Temeraire by Naomi Novik.
And UnIqUe_PrInCeSs, you probably don't love Malfoy, you love Tom Felton, with good reason.
Do you find that a lot of your favourite characters are really just the same character in different context?
