Well, back in 2006-2007, before my days of online gaming or interaction, I had attended classes at a Job Corps Academy. After the class/work day, you were free to watch TV, play games, and in general, socialize with other people. Right about this time I picked up the skill of playing Guitar Hero (quite naturally I might add) and was pretty good. I could play a couple of songs on expert, most of them on hard, but where I had the most fun was playing on medium. Well, my friends kind of envied my skill, and because I tend to be a perfectionist (hint to why I play on medium), one of them started calling me Zero, but he wanted to add the "i" to make it stand out and seem a little more, umm, asian (he was an anime fan). So it was soon spelled Ziero but pronounced Zero, adding the "i" for my first name, Indiana. While I was in Job Corps, it stayed that way for the GH leaderboards, with his nickname Sylver (pronounced Silver) in close second under my scores.
Later, when I started going online and making user accounts for things (YouTube, MySpace, etc), the name Ziero was usually always taken. So I added the 1986 (the year I was born). At times I just used Ziero86, and just once or twice I used Ziero1. So chances are, if you have encountered a Ziero1986 somewhere else, it is probably (most likely) me.
