I was introduced to “Tenchi”, the shy Japanese every-teen surrounded by the standard anime corral of supernatural characters with hyper-advanced technology, through the lighthearted comedy series “Tenchi in Tokyo”. Later I saw “Tenchi Universe” and was shocked to see that the zany, carefree gang from “Tokyo” was now (to me, “Universe” came first, I think) in a sci-fi melodrama.
This got me wondering about other times this happens in fiction. I get the feeling this is a bit more common in anime, with their endless versions of the same series (ex. Dragonball (Z), Sailor Moon (R, S, Super S)), but I know of at least a couple American TV series examples:
Batman (the 60’s live action series) and Batman: The Animated Series - do I really have to explain this?
Sonic SatAM and The Adventures of Sonic the Hedgehog: originally Japanese characters, yes, but they’re otherwise (North) American productions. The first was a serial action-drama that took itself way too seriously while the latter was a goofy, slapstick comedy that didn’t take anything seriously.
Are there any other examples of fictional characters leaping genres in between iterations, whatever the medium?
