So, as I'm writing the last bit of this book and an awesome new character showed up who basically makes me think lots of idle sequel thoughts. Anyway, this and a beta I've recently finished for my writing prof, lead me to a
PURGY POLL: Who are your favorite kinds of supporting characters? What makes them memorable and maybe prompts you to root more for them than even a book's protagonist?
Discuss.
ETA: Hair. I have dye sitting on my dresser. Alas, not until this chapter bites the dust. Until then, I shall avoid mirrors and ignore my glaring roots.
I call that "Deadline Hair"

I have it too. Deadlines on the 25th, the 1st, the 16th. *crying*
But I'm still going to do your poll *wipes tears*...
Call me silly but Spock was a great supporting character. I liked when you would sense his grudging admiration for the Cap'n. Even as a kid that came through to me. And because of his intelligence/ logicalness, you gave it some credence- it made him a nice foil for the hero. If the supporting character is an idiot, ya know, who cares if they think the MC is way cool?
Conversely, another fave supporting character of mine is Bigwig from W@tership Down. He was repeatedly described as being not too bright, but strong and resourceful. He had enjoyed a position of privilege in the old warren, so he didn't really need to travel cross country with Captain Kirk...I mean Hazel. (sometime I want to write an essay on the parallels btw WD and ST

) SO again, it makes a nice foil for the-- not necessarily strong or tough, but intelligent Main Character Rabbit. If the toughest toughie in Rabbitdom is following him, he must have a lot going for him.
I thought of another one while typing that, but now it escapes me! If it comes back to me, I"ll post it. Another fave trick of mine is when the hero is really a sidekick, like in K1dnapped by Robt L0uis St3venson.
