This year’s Arrowverse crossover, “Elseworlds” (watch the trailer here), will introduce several key new characters to The CW’s shared superhero universe. One of these is the Monitor (played by LaMonica Garrett), an omniscient being who watches over the entire multiverse and whose presence foretells dire things to come for the Arrowverse.
To help get you up to speed before the new crossover kicks off on December 9, here’s everything you need to know about the Monitor and his role in the DCU.
The Monitor: The Basics
In whatever state the DC multiverse exists, whether it consists of infinite parallel universes or a mere 52, the Monitor exists to oversee all of creation. This omniscient being has existed since the dawn of creation. His job isn’t simply to observe, but to protect the multiverse from his twisted doppelganger, the Anti-Monitor.
