Game Freak, the primary studio behind Pokémon, suffered a massive data breach. The hacker released thousands of files supposedly pertaining to the creation and development of Pokémon, containing unreleased concept art and even scrapped ideas for Pokémon games, which is where the Typhlosion drama comes in.
According to one unconfirmed report, the leaked documents included a concept for a series of fable-like stories that explore the relationships between Pokémon and humans. In one of these stories, a Typhlosion kidnaps a young girl, marries her, and has a child with her. The story reads like something from Grimms' Fairy Tales or a myth, and it's managed to creep a ton of people out. Over the past three days, the tale has inspired hundreds of people online to make Typhlosion memes and art in response to the story.
