My nickname, also my character's name, occured from the single word that remained through all my nicknames, Killer, in combination with a reference to my chara's powers, Spirit. Thus Spirit Killer was born (out of the ashes of Da Killer, which replaced Ze Killer, which gave the boot to Killer253, and that would be the end of the railroad). XD
I got mine while trying to create a website.
I was looking for a free template to start off on and I found one called INVADER and was based on the classic 'Invaders' video game. Because I didn't want this as my site name I changed it by adding an X to the start which was brought on by the X parasite from 'Metroid: Fusion'.
I started to use it as my nickname as it was different than my usual name of GOLDENCHOCOBO and almost no one else has it...
When I was young, I had a white manx that loved sugar cubes...
From there, the name was born
P.S. My next cat after that was a balinese cat that was trained in the art of flushing toilets *lol* (Yes, I trained it). If I named myself after that cat, I probably would've been called "2000 flushes" or something
I got mine from a book >_< I was reading it when trying to think up an e-mail name, and I liked it. I actually remembered it wrong, it's supposed to be Dominion not Domain. I think mine is better ^_^ Now I use it everywhere.
1. My email uses it...
2. Named after my Anime/Manga character Jago Mizukami.
Who was made from a combination of traits from DBZ, Sailormoon, Tenchimuyo!, and Inuyasha. He is Saiya-Jurai-jin.
I've used this name... for quite a while... since about 1999 or so... before I even joined Deviantart... His character changed appearance wise for a while before I settled on his present design... but basically that's where I came up with the name... "Jago" sounded cool to me, also the name of a character in Killer Instinct... while "Mizukami" just means "Water-Spirit" or "Water-God"... anyway that's the origin of my Deviantart name / my email.
