I know everyone has been holding their breath waiting for the answer…
My avatar is ‘Dust Puppy’ from the comic Userfriendly from the late 90’s.
“Born in a server from a combination of dust, lint, and quantum events, the Dust Puppy looks similar to a ball of dust and lint, with eyes, feet and an occasional big toothy smile. He was briefly absent from the strip after accidentally being blown with compressed air while sleeping inside a dusty server.”

While he appeared in Userfriendly the lore was that he was an excellent Quake player, so the Quake3 developers put a sticker on the understide of Q3DM19 of Dust Puppy as an Easter Egg.
