Not really a “comic” comic, it’s an Original Graphic Novel or OGN.
FTA:
“just recently, DC announced it was serializing the original 2020 Primer OGN in classic comic book issues beginning in March 2024, with the release scheduled to finish off just in time for the sequel, Primer: Clashing Colors, in summer 2024.”
Well, there are degrees of “for kids”. :)
Primer is maybe overly simplistic in writing and vocabulary, but it’s fine for the audience.
Marvel and DC both have books that can skew younger or older depending on the book.
