My username when I first joined The Escapist was "RocketPocket," but I didn't really care for it. After James Cameron's Avatar was released in theaters toward the end of 2009, I became a bit of what the internet would call an "Avatard" for a little while. Basically, I took the first letter of my first name, and added "of the Na'vi" to it, because I thought it rolled off the tongue rather well.
As for my avatar, it changes constantly. Right now though, it's a badass gif of Ghost Rider I found and edited/optimized for the Escapist.
