Obito had never witnessed Madara Uchiha's power, but out of all of them, he had spent the longest by Madara Uchiha's side.
No one feared Madara Uchiha more than Obito did.
Obito chuckled awkwardly. "Sister Kushina, I may not know how, but the Tobi inside me does."
"Tobi is a special White Zetsu with a mind of his own."
The White Zetsu inside Minato was like a pet, with little awareness. If Minato spent some time with it, he could tame it without needing the Sharingan.
But the White Zetsu inside Obito had a mind of its own, making it difficult to tame.
Kushina immediately brightened. "Then what are we waiting for? Hurry up and have the Tobi inside you teach me the Spore Technique."

"If we separated some White Zetsu Cells and cultivated them with Kushina's Chakra, we might be able to grow a White Zetsu in no time."
Just like Minato's regeneration, White Zetsu served as a tool. At its core, it was simply another miraculous application of Yang Release.
Kushina nodded and patted Minato on the shoulder. "Minato, that little head of yours really is useful."

The Third Hokage glanced out the window at Kage Rock, then clenched his fist.
Even if it cost him his life, he would protect the village the Previous Hokages had given their lives to
