When on the same side as Dondozo, Tatsugiri enters its mouth, raising Dondozo's Attack, Defense, Special Attack, Special Defense, and Speed by 2 stages. While activated, Dondozo cannot switch or be forced out, even if Tatsugiri faints. Red Card items trigger but have no effect. Order Up provides additional stat boosts based on Tatsugiri's form: Curly Form raises Attack, Droopy Form raises Defense, and Stretchy Form raises Speed. Does not activate in Multi Battles or Tera Raid Battles.
