The information from TVLine has left out some crucial information, though. Something we don't know right now is whether or not LaMonica Garrett will appear as Monitor and Anti-Monitor in all episodes. The actor will be doubling up this year in at least some of these episodes as Monitor's anti-matter opposite, who just so happens to be one of the biggest villains in DC comics. And, you know, who's also looking to destroy the entire multiverse, so clearly this guy will be very important, even though he's not the only bad guy who will be around.
