Poof

Poof was a self proclaimed "bitch ass motherfucker" and fairy baby. He was the mastermind behind such problems as Climate Change, Nessa, Bad music and whatever Secondlife is.

Early Life
Poof was born in China due to Timmy wanting to ruin the entire franchise. Afterwards, Poof became a target of Half Life Scientists who needed him to study the Resonance Cascade that happened at Black Mesa. He was also known as a "Satanic Ritual Abuser" who was criticized by Satanists for being "A total asshole with what he does"

Death
Poof was shot to death by Half Life Scientists in late 2007 for a lack of cooperation and hostility towards Black Mesa research personnel
