'Crisis on Infinite Earths' Part 5: Arrowverse crossover deviates from comics plotline, brings back multiverse
This article contains spoilers for 'Crisis on Infinite Earths' Part 5
The final fight between Oliver Queen/Spectre (Stephen Amell) and the Anti-Monitor (LaMonica Garrett) saw the latter being defeated. While it did see Oliver sacrifice himself as well, it paved the way for the rebirth of a new multiverse. Emphasis is on the word multiverse as the Arrowverse crossover saw the recreation of more than just one earth, the Earth-Prime. It is shown as the place where Team Supergirl, The Flash, Batwoman and the Legends exist while the other Earths show the Titans (Earth-9), Kingdom Come Superman (Earth-96), the Green Lanterns (Earth-12), Doom Patrol (Earth-21), Swamp Thing (Earth-19), and most importantly, the Super Friends (Earth-2).
This is a sharp contrast from how it ended in the comics. The final battle ended with the formation of one universe. The single universe was split again in the 'Infinite Crisis' crossover. For now, it does like the Arrowverse has major plans going forward and it started with the epic battle that also drew Oliver Queen's arc to an end. 'Crisis on Infinite Earths' was a five-part series that premiered on December 8 and culminated with the opening Season 5 of 'Legends of Tomorrow'. For now, a major 'Crisis' has been averted. However, new Earths means new heroes and also, new enemies who will pose more formidable threats to the heroes.
To be noted is the formation of the Justice League that The Flash (Grant Gustin) creates should all the superheroes need to gather to protecting the world against more danger. Two years after the league used a similar facility in the "Invasion!" crossover, giving us the official Hall of Justice.
