I am someone who likes all sort of avatars cause normally avatars are used to describe one's personality and they are so many unique and nice avatars out there that I hadn't seen, or heard about.. So tell me about your avatars?
As for me own...
My very first avatar/icon I have ever used was just the Morrowind Icon. I used it to show that I was a Morrowind player back then.
I then had an animated avatar of a Golden Dragon that was glowing. I used this avatar to symbol Luten, who is the main character of a Short Story-Line that I've written. He was a Golden Knight but later became a Dragon.
Then I just had the Zaros Symbol glowing for like a few days. It was to show that I am a Zarosian in RuneScape.
After that, I had an avatar of a Purple Knight with the Zaros symbol on him to show that I am a fan of medieval and I am a Zarosian in RuneScape.
The next one I remember is a Purple Dragon that was flying in the air with the Zaros symbol on his forehead. This was to show that I am a fan of dragons, as well as my roleplay character on DevART chats was a dragon, and that I am a Zarosian on RuneScape. I am still using this one on DevART and other sites.
My newest one is what I have know. Rainbow Dash with the quote "I'm a Brony. Dash with it.". It is showing my favorite character in MLP FiM and that I am a Brony and don't care who knows...Just deal with it!
