Obito

All this changed for Obito during the Battle of Kannabi Bridge in the Third Shinobi World War, where half of his body was crushed in a collapsing cavern, and he was forced to accept his fate.

Despite his efforts being in vain initially, Obito did not give up as he earnestly fought against Madara to help the Allied Shinobi Forces.

Despite his rivalry with Kakashi, Obito had no darkness in his heart until Madara saved him from the collapse.

He totally wiped them out with the help of Obito on the condition that they would let him keep his younger brother, Sasuke, alive.

Madara's jinchuriki form was far more powerful than Obito's, nearly equal in power to Hagoromo himself.

Tobi/Obito helped create the Akatsuki to fulfill Madara Uchiha's goal of plunging the Earth into a permanent dream world.

With her paper ninjutsu techniques, she was able to overwhelm Obito Uchiha.

Under Obito, he completely destroyed Kiri.

It even surpassed Kakashi vs Obito in some ways.

Just one hit from this technique would disintegrate any person, as seen when it killed Obito Uchiha with very little effort.

Obito's origins were much like Naruto's own, especially in the way of his personality and mannerisms.

Sakura was in dire straits when Obito asked her to stab him in the eye.

What doesn't make sense is how it unlocked in both his and Obito's eyes as if they were interconnected by a tether.

During the Fourth Shinobi War, Obito tries to fatally attack Naruto and Neji sacrifices himself instead.

Obito was then 14 years old.

This power shift was a background for later conflicts between Nagaya and Fuhito's four sons during the reign of Emperor Shōmu (formerly Prince Obito).
