While not directly about multiverses, 'Watchmen' broke ground in comic book storytelling for its complex narrative and philosophical depth, paving the way for more sophisticated explorations of identity and reality within the comic book medium, which 'Spider-Verse' then applied to the multiverse.
The casual acceptance and visual depiction of multiple, often absurd, parallel versions of a character, and the fast-paced traversal between them, show a conceptual influence from 'Rick and Morty's' multiverse antics.
