"Kiri then caught the Three-Tails again, this time sealing it in a young Yagura Karatachi."

"Following Madara's death, Obito took on Madara's identity, and at some point took control of the Fourth Mizukage with genjutsu."

"The Academy's graduation methods were discontinued after Zabuza Momochi, not yet a student himself, killed an entire year's graduating class."

Yagura was maybe like 16 when he was controlled. Obito and Zabuza are the same age. Zabuza was like 9 when he did that. How did Obito control Yagura when he wasn't even supposed to be Tobi at that time?
