The main characters would likely include Oliver Queen, also known as the Arrow. He's central to the Arrowverse and would play a major role in a Crisis on Infinite Earths fanfic. Other important characters could be Barry Allen, the Flash, as his powers and his role in the multiverse are significant. And of course, Kara Zor - El, Supergirl, who has her own unique abilities and would be involved in the multiversal events.
One interesting plot point could be the different versions of characters coming together. For example, various incarnations of heroes from different Earths might team up in ways not seen in the original Crisis on Infinite Earths. Another point could be how the Arrow characters adapt to the multiversal chaos. They might face challenges that test their skills and morals in new ways.
The merging of different Earths is also a top story. This event shakes up the entire multiverse. It changes the relationships between characters, creates new alliances, and redefines the very fabric of the superhero universes. Characters who were once strangers from different Earths now have to learn to co - exist and fight together.
One idea could be exploring the backstories of minor characters who get caught up in the Crisis. For example, how an ordinary person from a small, unremarkable Earth copes with the multiversal chaos.
Superman is an important character. His strength and leadership play a crucial role in the events. Batman also stands out. His strategic mind helps in planning against the threats. And of course, the Anti - Monitor as the main antagonist is extremely important as his actions drive the whole crisis.
Crisis on Infinite Earths in the comics concludes with a battle of epic proportions. Heroes unite from different realities and, in the end, the fabric of the multiverse is altered in ways that have long-lasting effects on DC Comics.
Damage is another character that could be highlighted. He's not as well - known as some of the big - name heroes, but his powers and his internal struggle could make for an interesting sub - plot within the Crisis. He could be a wildcard factor that changes the tide of some battles.
One of the main plot points is the convergence of multiple Earths. Different versions of heroes from various Earths are brought together to face a threat that endangers all of existence. Another key point is the struggle against the Anti - Monitor, a powerful and malevolent force seeking to destroy the multiverse.
