Aw don't make fun! I know that people don't actually look like their avatars (well, unless they're Steph, or A-G-A or SS, anyway). It's just if they've stuck with the same one forever, that becomes the first association in my mind.
"How dreadful!" cried Lord Henry. "I can stand brute force, but brute reason is quite unbearable. There is something unfair about its use. It is hitting below the intellect." ~ Oscar Wilde - The picture of Dorian Gray
When marmalade.sunshine's avatar was Mew, I was very much tempted to make mine Mewtwo, but he isn't quite as fitting to me as Bowser. When "Change-Your-Avatar-to-a-Pokemon Month" comes up, Mewtwo will definitely be my pick.
I also like the cartoon in Tamske's avatar. I'd like to see more of them for all of the functions.
