The format comes from Pixar's The Incredibles and its hero Bob Parr, also known as Mr Incredible. In late 2021 edited portraits of the character getting progressively more distorted went viral on YouTube and TikTok as the Mr Incredible becoming uncanny meme, usually telling a story in stages. Each numbered phase adds a darker edit and a more uneasy tone. Phase 3 became a reusable shorthand online because it sits in the middle, recognisable as uncanny without reaching the extreme later phases that followed.
