My name comes from a mutation of my favorite color, Silver (as well as one of my favorite pokémon rivals), and the acronym for Operating System (OS), due to my love of computers. Also, I just thought it sounded cool when I thought it up. XD

I first used it back on Pokestadium, and changed it to 'Sir Sivelos' when I migrated here. The 'Sir' part comes from the fact that, well... Again, I thought it sounded cool.
