In "Countdown to Final Crisis", one of the storylines follows the Monitors in their headquarters. One Monitor has taken it upon himself to eradicate inconsistencies within the universes, characters such as Duela Dent, whom he kills. At first, the other 51 Monitors are more devoted to merely watching the multiverse and intervening only when truly necessary. Throughout the "Countdown", each of the Monitors begins to develop disparate personalities and physical characteristics which reflect (to some extent) the nature of their universe and each Monitor takes a name for themselves. In "Final Crisis", one Monitor reflects that this is because interaction with the worlds of the Multiverse has allowed time itself—beginnings and endings—to enter their haven. Notably, Rox Ogama, disciple of the Dark Monitor, Mandrakk, is charged to look after the universe of "", in which Batman also becomes a vampire.
