Apollyon
From Sheapedia
Apollyon is a deceased 26-year-old male member of RINGS Communities. He was apparently a Satanist, but more twisted and disturbed than most others of the Black Mass. He also seemed to be professional at gathering information, and would sell it to the highest bidder.
History
He first appeared at RINGS on December 6th, 2007, creating a topic called 'four horsemen' containing only the message "This looks like a fine place to begin."
He was inactive until the destruction of the original Tape Busters building in the Akihabara district of Tokyo. He attempted to kill recently resurrected member Neo-X, but ultimately failed. Neo-X then killed him.
