An internet celebrity/4channer who has a collection of flash animations, in which he's notorious for yelling into the mic.

In addition to his animations, he has a comic named "Impulse" (with a backward E) on his website, despite its slow-moving update pace. If any at all.

Everyone's gay for Xenon, whether you want to admit it or not.

One fateful day, in a science class, a discovery was made. As a result, a name was born (from a noble gas found in the Earth's atmosphere). He always says mew, and yet denies he's a furry... And is either a drunk person or on crack. It seems that this cRaZy orangutan can still switch back to normal mode when a teacher collects homework, it is truly a phenomenon.
Wait, what the hell are they doing????!!!!!!! They must be a Xenon...

Mewwwwwwwwwwwwwww- Xenon
