1. Kakashi's Traumatic Move: When Naruto was a genin, Kakashi tested his team's comradeship by playing the bell-stealing exercise. Kakashi used his signature move, Thousand Years of Death, to surprise Naruto from behind. This may have left a psychological trauma on Naruto.
2. Sakura's Powerful Punches: Sakura, Naruto's childhood friend, frequently used violence against him in ninja school. After becoming Tsunade's apprentice, Sakura gained Tsunade's super strength. Fortunately, Naruto's Uzumaki bloodline allowed him to endure Sakura's powerful punches.
3. Hinata's Devastating Attack: Hinata, Naruto's daughter, can freely activate or deactivate her Byakugan. Once, when Boruto angered Hinata, she used a pressure point attack on Naruto, instantly knocking him down and even affecting the Nine-Tails inside him. This power may have surpassed the Six Paths.
4. Pain's Destructive Almighty Push: During Naruto's battle with Pain, he suffered greatly from Pain's Almighty Push. Only by utilizing senjutsu and the power of the Nine-Tails, does Naruto manage to defeat Pain.
The consequences would have been unimaginable without these powers.
5. Overcoming Genjutsu: Naruto used to be afraid of genjutsu as he didn't know how to break free from it. However, now that Naruto and the Nine-Tails have become good partners, genjutsu doesn't pose much of a threat anymore.
