Cannibal is an Oblivion. An Oblivion is created when a person loses the will to live. Cannibal (named Jack when he was a human) was a leader of a Spec-ops team that was sent to a church that was reported to have monsters lurking around. The leader's teammates were killed one after the other by an unknown force. When the heroes arrived they found the leader hiding in fear with blood all over his mouth. When the leader reliesed that he ate his teammates he turned in to an Oblivion and started to rack mayhem around the church (and trying to kill the heroes at the same time).
