Fan Casting The Anti-Monitor in Justice League: Crisis on Infinite Earths

The Monitor's infamous counterpoint - his 'brother', controller of the Antimatter Universe, and now also awakened again due to the recent events of the Multiverse. Both in the past waged a million-year war, in the Monitor's effort to quench the insatiable desire for conquest of his chaotic counterpart, who aimed to destroy all positive matter universes. They were born together, and now, if both must be destroyed to save trillions of worlds, it's a price the Monitor is willing to pay.
