Crisis On Infinite Earths is the biggest Arrowverse crossover event ever. During episodes of Arrow, The Flash, Supergirl, Legends of Tomorrow and Batwoman, many DC comics superheroes made appearances. Here are our 15 favorite Easter eggs from the CW crossover. (Warning: Spoilers!)
Taking place over five nights, each of the CW/DC shows pitted its heroes against the Anti-Monitor--an evil being trying to destroy the multiverse. And because this massive event contained every hero--and some villains--from CW's Arrowverse, of course there will be some Easter eggs and references to other DC properties from movies to forgotten TV shows to comic books.
In our list of the best Easter eggs, there are references to Batman 66, Batman 89, Superman II, Batman: The Animated Series, Lucifer, Smallville, Constantine, the Justice League movie, Green Lantern, Super Friends, Kingdom Come, Birds of Prey, and more.
