welll, he was previously an angel. He started questioning his leader, Majesty Of Death (aka eye ball mans) and their rules. That caused Death to send phil to earth with less than half of the angelic power he had, almost as an attempt to fix phil.
Unsurprisingly, it didnt work. soo, Majesty Of Death decided to take total control of his consciousness. and thats where we currently are!
v sad :'D
