The Difficulty of Naruto's Shadow Clone Jutsu: Naruto's Shadow Clone Jutsu is a powerful technique that creates clones with identical characteristics to the original. Naruto's clones have played a significant role in his battles, easily defeating elite opponents like Kakuzu. 

However, Pain was able to see through the clones and defeat one of them. Haku-Dō also fell victim to Naruto's clones when he mistakenly targeted a clone and was struck down unexpectedly.

Even Sasuke Uchiha and Kaguya Ōtsutsuki struggled against Naruto's clones, as their powerful donuts were unable to perceive the true nature of the clones. 

In conclusion, Naruto's Shadow Clone Jutsu is a formidable technique that confuses even the most powerful opponents. No one has been able to see through the clones' disguises.
