Mcgahey 

The anti-christ, who, in his complete and total domination of a band, has formed a coalition of multi-cultural acolytes willing to fulfill his ever will with "CONVICTION". Fan of the words "not acceptable" and "potential." Also, one ear is bigger than the other.

"Hey Mr. Mcgahey." "I rule you."
