The info:
Some dude leaked a bunch of stuff from Gamefreak, the leak is now dubbed “the teraleak” due to how much was leaked. In the leak there are a bunch of seemingly scrapped lore stories.
One of the lore stories is about a Typhlosion who groomed a girl and had a child with her.
The stories all appear to be in the format of standard folklore (which as you know is never pretty in of itself, look at ancient Greece’s bullshit). Nintendo tends to take existing yokaj folklore stories and substitutes Pokémon in them, which is how you get info like “Froslass will lure men out of their house to freeze them” and “hypno will make children fall asleep and kidnap them.” Typhlosion got the most attention because theirs specifically mentions “girl.” There is a slaking one where something similar happens but the term “woman” is used. All stories appear to be written by the same person and there is no confirmation that these stories are actually part of the leaks yet as far as I know.
