I chose my name because it's the name of my (at the time) favourite Oddworld fan-character. I was going to use the handle 'Evil-spark-dragon', which is my DevniantART username, but I wanted something that was a bit more Oddworld-ish-sounding.
Of course now it's kinda weird whenever I wish to RP with Marvak, everyone thinks I'm RPing as myself instead of my character, which kinda sucks. =P
