Speculating About Hanzō's Strength

Fugaku didn't know whether these Tailed Beast cells would prove useful in the end. Perhaps gathering flesh from all nine Tailed Beasts could produce the Ten-Tails' Chakra.

Late in the Third Shinobi World War, Orochimaru had scraped a little powder from the Eight-Tails' severed horn and, after years of research, grown it into a complete horn.

Fugaku lacked Orochimaru's research skills, but he could cultivate these samples slowly. Besides, he had already signed Summoning Contracts with several Tailed Beasts.

He could summon them whenever he needed them. For now, the flesh and cells were a move made in reserve. They might prove useful in unexpected ways.

He walked over to the Genetic Material extracted from Uchiha Tenjo's cells. After a period of cultivation, the cells had clearly divided many times and grown much larger.

Fugaku took the sample out and studied it carefully under a microscope. All this Genetic Material had been extracted from Hereditary Cells complementary to his own Sharingan.

Many of the cells had fully developed and were ready for the next stage. He divided the flesh into three pieces.

One was large and two were small. He returned the large piece to a Cultivation Tank and used the two smaller pieces for cloning.

He would create two bodies whose genetic information complemented his Sharingan. Once he cultivated their Sharingan into Mangekyo Sharingan, he could combine them into an Eternal Mangekyo Sharingan.

The so-called eye transplant was not simply a matter of swapping eyes. If it were, the Uchiha would have produced many people with Eternal Mangekyo Sharingan long ago.

Rather than a transplant, it was closer to a fusion.

The Pupil Power and Genetic Material of two pairs of eyes fused, making their genes complementary.

It was like joining two uneven semicircles into a perfect circle. That
