War is the youngest of the four Horsemen of the Apocalypse and once feared by angel and demon alike, even the Charred Council was wary of him. He rides the horse Ruin.
War once openly defied the Charred Council and easily slayed the small army they sent to retrieve him. The other three horsemen eventually had to intervien at which point War displayed his true strength taking on the other three and almost defeating Fury. Death the oldest of the horseman was not easily injured and showed no pain as War impaled him with his sword Chaoseater. The fight was ended when Death cut off War's left arm.
During the events of the first game War is accused by the Charred Council of bringing the 'End War' before its time and is sentenced to death. He persuades the Council to allow him to clear his name and is sent back to earth. The Watcher is bound to War by the Council to keep him in check.
