Honestly Sakura & Chiyo vs Sassori is the best anime fight of all time. The fight constantly went from bad to worse for the protagonists. The two they chose for the fight were very important for the bad to worse dynamic because anyone not named Sasuke or Naruto had a relative chance of dying throughout the series. Sakura and Chiyo weree such perfect choices as well because neither had particularly powerful jutsu so they constantly had to use their wits and guts to overcome every trick Sassori had planned. And they did it together which caused even more creativity to be used throughout the fight and made it more plausible that they were able to defeat such a powerful fighter who had the use of the most powerful Kazukage. And lts not forget the ironic and powerful imagery of the ending.
