Mr Incredible is the hero of Pixar's The Incredibles, but online he became the face of the becoming uncanny meme, a format in which his portrait grows progressively darker and more distorted as a situation worsens. Creators divided the progression into numbered tiers or phases, with tier 4 sitting in the middle of that slide, unsettling but not yet at its most extreme. The format spread through short-form edits and compilation videos, where each tier got its own matching sound, and it remains popular because the familiar character makes the descent easy to follow.
