I've started viewing Janet as a shapeshifting anime girl since she changes her avatar with decent regularity. A very tall shapeshifting anime girl since she posted in the rage thread about it.
Facts about people that stick in my head affect my image of them. I remember when Jackrabbit was like 12 so he's always some kid to me, and Truean is always a lawyer-suited avatar, be it cat or penguincat.
Toony is a troll because of that gif avatar he had a long time ago of some troll-looking person in a boat.
Jesus, we are both old, old people. And I'm still a kid.
Anyway, to go over a few more images other than the ones I talked about before, Vester is a strongly chinned, dangerously good martial artist with a vest and that probably stems from the strong chin in her avatar, the name and the fact that she is Asian (racisim oh noooo) and so she always had kind of a weighty, sure footed feel to her mental voice. Vector is some kind of calming floating entity shaped vaguely like some fruit that looks delicious so she's quite chill whenever I hear her speak. Duke 2.0 has a very regal voice, but not in the annoying sort of way; rather in the "sit down, shut up and listen to this man" sort of way. I cannot disassociate him with the avatar of the man with the Golden Hat he used to have. Blargity Blarg well, I've met him in person so that's pretty much it for my preconceived ideas but I still can't help but imagine his incredible disembodied godlike hair talking to me whenever I read his posts. Toony is, well, Kamina but also a dash of troll rave, and he has probably the most distinctive voice on the forums after Aqizzar for me: bitingly sarcastic and very witty but never drawing attention to the fact. I have no idea how I'd describe it other than that.
