Philip Reardon was the Ten-Eyed Man, one of the most strange villains that the Batman ever faced.
An insane supervillain, Reardon was locked away in Arkham Asylum where he resided for a while. After the Joker's Daughter began acting on behalf of Deacon Blackfire, Reardon retreated into the Gotham City sewers where he opened up a portal to the Hellmouth and tried to sacrifice a young girl named, Jade. Unfortuantely for Reardon, Jade was under the protection of Killer Croc. Again unfortunately for Reardon, Croc was allied with Jason Bard and the Batman, who attacked Reardon. Reardon's dastardly plans were put to an end as the Hellmouth was closed and Jade safely rescued.
