He's just there.
I'm not sure how to explain it.
I'm told he went by 'Indolence)Bio' and 'isometimesexpo'. I vaguely remember he had two sidekicks named Banana and Speed that weren't very good.
He hasn't really made much of an impact, apart from making comments on the boards that people largely ignore. He's an almost decent 2v2 partner, and takes verbal abuse really well.
I guess he's just like ketchup for your french fries, you don't really need him at all, but you can use and dispose of him as you see fit.
