Is there a fanfiction where Naruto gets Toph pregnant?
I'm not sure if there is exactly a fanfiction where Naruto gets Toph pregnant. Fanfiction can cover a huge variety of scenarios, and crossovers like this are not unheard of. But it's also not a common or typical combination that one would immediately find. You might have to search through some specialized fanfiction websites and dig deep to see if such a story exists.
There might be such fanfiction in the vast realm of fan - created works, but it would be a very non - canon and strange crossover considering Naruto is from the Naruto series and Toph is from Avatar: The Last Airbender. However, this kind of crossover fanfiction often explores unique and unexpected scenarios.
In the world of fanfiction, almost any scenario can be created. But Naruto and Toph are from two completely different fictional universes. While it's possible that some creative fan has written a story where Naruto gets Toph pregnant, it's likely to be a very niche and perhaps even a little out - there piece of work. There are so many different types of fanfiction, from the most romantic to the most outlandish, and this would fall into the more outlandish category if it exists.
