I slowly starting to piece together why I might be recommended Hey Arnold, although I think what weirds me about it as I didn't specifically intend my web comic and short film as a Hey Arnold or Charlie Brown variant. Superficially the idea seems completely ludicrous to me, despite being a fan of Craig Bartlett.

It isn't so much that Hey Arnold isn't dark in its own way, but paranormal romance pairings isn't really what's implied in shows in Nickelodeon. At least not in your typical Family Friendly show. Plus as I'm learning over time, intentionally or not, it seems like a significant chunk of my readers speak Spanish. Despite the fact I'm learning Francais.

With the kind of character Hemato-Tomato is, I think my fear is that people would misinterpret Hemato and Ehena ( Japanese for Helan or Anna ) as a darker variation of Arnold and Helga.

I'm not even sure if "Hey Arnold meets Elfen Lied" would even be a good hook.

( For context, I considered the idea of working as an apprentice for an established animator in US TV. )
