The '252+ SpA Choice Specs Beads of Ruin Tera Fire Chi-Yu' meme stems from the competitive Pokémon community during the launch of Generation 9 (Scarlet and Violet). Chi-Yu, one of the Treasures of Ruin, became legendary for its absurd offensive potential, where its Beads of Ruin ability effectively cuts the opponent's Special Defense, allowing it to punch through even the sturdiest 'walls' like Blissey or Toxapex. The meme usually features the specific damage calculation string used in Smogon's calculator, highlighting the ridiculous fact that a tiny goldfish can incinerate the entire metagame with a single Overheat. It is frequently used to mock power creep in Pokémon or to celebrate the chaotic satisfaction of a one-hit knockout (OHKO).
