Ranking Each Arrowverse Crossover From Worst To Best
4. Elseworlds
2018's Elseworlds saw the introduction of characters such as the Monitor and Batwoman and signaled the forthcoming Crisis. Unfortunately, this meant the crossover was less so a contained event and more so set-up for bigger (and more interesting) things to come.
Barry and Oliver undergo a Freaky Friday-esque event after Arkham Asylum doctor John Deegan rewrites reality after being empowered by the Monitor with the Book of Destiny. The cosmic powerhouse is traveling from universe to universe to test their heroes in an effort to form a team that will be ready for an upcoming Crisis.
The event is suitably epic, as the body switched heroes are joined by Supergirl, Superman, the Earth-90 Flash, and Batwoman as they face off against Deegan and seek to undo his reality-warping hijinks.
However, the crossover suffers from the sheer introduction of these individuals and concepts, and as a result, does not get a chance to breathe or feel complete like its counterparts.
