Crisis on Infinite Earths (Arrowverse)
The "Crisis on Infinite Earths" was a five-part crossover event within the Arrowverse, a shared universe of interconnected television series based on DC Comics characters airing on The CW. It adapted the iconic 1985-1986 DC Comics storyline of the same name.
The crossover involved the heroes of Arrow, The Flash, Supergirl, Legends of Tomorrow, Batwoman, and Black Lightning, uniting to fight against the Anti-Monitor, a cosmic entity intent on destroying the multiverse. The Anti-Monitor was unleashing waves of antimatter, systematically obliterating each of the infinite Earths in the multiverse.
The heroes, led by the Monitor, initially attempted to save as many Earths as possible by evacuating their populations to Earth-1. However, as the Anti-Monitor grew stronger, their efforts shifted to finding the seven Paragons: individuals with the purest hearts and strongest wills, destined to be the last hope of the multiverse. These Paragons included Supergirl (Hope), Batwoman (Courage), The Flash (Love), Martian Manhunter (Honor), Sara Lance/White Canary (Destiny), Superman (Truth), and Lex Luthor (Humanity).
Throughout the crossover, various characters made sacrifices, including Oliver Queen/Green Arrow, who died saving billions of people and later again to restart the multiverse. The heroes eventually faced the Anti-Monitor in the Dawn of Time, where they were able to defeat him and recreate the multiverse.
The newly formed multiverse was consolidated into a single Earth, designated Earth-Prime, merging elements and characters from different previously existing Earths. This allowed for new storylines and character interactions within the Arrowverse.
The "Crisis on Infinite Earths" crossover significantly impacted the narrative landscape of the Arrowverse, resetting character histories, combining disparate storylines, and opening the door for future crossovers and character introductions. It served as a culmination of the shared universe's narrative threads and a reset for future storytelling.
