In 'The Dark Tower' series, Roland Deschain is the main character. He is a gunslinger on a quest that spans across different realities. In the 'Sliders' TV show, Quinn Mallory is the one who invents the device that allows them to slide between universes, and he is a central figure in their adventures through the multiverse.
In 'Spider - Man: Into the Spider - Verse', Miles Morales is a central character. He is the new Spider - Man from his universe and has to team up with other Spider - People from different universes like Peter Parker from an alternate reality. In 'Doctor Strange in the Multiverse of Madness', Doctor Strange himself is the main character. He has to navigate the dangerous multiverse to stop various threats.
There are many main characters as it often features well - known DC characters. For example, Batman is a common character in these stories. His character can be drastically different in the Dark Multiverse, perhaps more of an anti - hero or even a full - blown villain. Superman also appears, sometimes with a corrupted version of his powers or a twisted sense of morality. Wonder Woman might be another main character, with her own unique challenges and changes in the Dark Multiverse setting.
Perhaps there are original characters created by the fanfiction writer. They could be individuals who have unique powers or knowledge about the multiverse and play a crucial role in the war. For example, a character who can sense the weak points in the fabric of different universes and uses that to plan attacks or defenses. There might also be characters who are versions of existing characters but with different personalities or abilities due to the differences in their respective universes.
Obviously Naruto is one of the main characters, especially in his 'god' form or different multiverse versions of himself. Sasuke might also be a key character as he often has a complex relationship with Naruto. And there could be other characters like Kakashi or Sakura who interact with this new, more powerful Naruto in different ways depending on the plot of the fanfiction.
In the world of books, 'The Dark Tower' series by Stephen King has elements of a multiverse. It combines different worlds and dimensions in a complex and fascinating way.

It was about a group of people who slid between different parallel universes, each with its own set of problems and oddities.
One of the best is 'The Dark Knight Returns'. It presents an aged Batman coming out of retirement in a gritty, alternate future of the DC Multiverse. It's a story that challenges the traditional view of superheroes and their place in society.
