Last month it was revealed that this year's Arrowverse crossover would introduce the concept of Elsewords (also what it would be called) and introduce The Monitor, played by LaMonica Garrett. In the comics, The Monitor was a power being who sought to learn all the secrets of the universe. He is probably most well-known for his role in the Crisis on Infinite Earths series.

Looks like someone was caught reading while he was supposed to be monitoring.
Elseworlds starts on the CW on Sunday, December 9 in The Flash, and continues on Monday, December 10 with Arrow, and concludes on Tuesday, December 11 in Supergirl. Other new characters you'll be able to see in the crossover are Batwoman and 90s Flash.
