-I doubt there is any Self-Inserts for this series.
I have seen or heard of many fanfics of Diary of the Wimpy kids, some are weird, some are atrocious, and some are just cringe. But I haven't yet seen a self insert of it.
This fanfic I am thinking of is based on a mixture of the movies (There are only 3, not 4!!!) and the book series, though the movies would be more of the main backdrop than the books, as they're kinda sporadic and not really charming in terms of main characters.
Also, It would be a mixed world type as I would add some shows/movies or other books into it, but it has to be something taken place in a more real life or realistic type setting.
-Here's some of my main ideas on this fanfic,
Gets reincarnated at toddler age, based on the original trilogy movie and the book series, life improvement, becomes a pseudo renaissance guy, might have a few live action movies/shows/books mixed in, slice of life, romance, drama.
These are some of the worlds I am thinking of mixing in:
-Dork Diaries
-Big Nate
-Thirteen
-Pitch Perfect
-6teen
-Gravity Falls (Minor)
Keep in mind, it will be all subjective to change if I feel like it needs to.
