Known initially as The Radiant One, the first son of the limitless Monitor, who first mapped the Multiverse. It is not made clear whether he is the same being as the original, nameless "Monitor" of "Crisis on Infinite Earths", or the original "probe" created by the Overmonitor intelligence to explore the Multiverse. After becoming steadily more corrupted by exposure to Bleed and the stories within the Multiverse, Novu created a thought-robot in the shape of Superman as protection against the foretold foe of the Monitors, Mandrakk, and a tomb for that foe which would not open until a Doomsday clock mounted on its doors reached zero, at the same moment as the Superman Thought-Robot became active. He then entered the tomb and allegedly "Gave His Life To Chain The Beast In Darkness".
