To analyze Obito's moves and abilities, Tobirama joined forces with the First's Wood Clone against Obito Uchiha in Ten-Tails Jinchuriki Mode. The brothers were both blasted apart at the waist by Obito's Truth-Seeking Orbs in their fluid form, yet at the very instant he was shattered, Tobirama not only slapped several explosive tags onto Obito's body but also marked him with a Flying Thunder God formula. This showed just how fast Tobirama's strikes were. Then Hashirama's Wood Clone extended two tree vines to bind Obito, allowing Tobirama to bombard him with Mutually Multiplying Explosive Tags.

At this moment, the Second Hokage calmly analyzed Obito's abilities based on his combat experience from when he was alive. He concluded that Obito's technique was based on Yin-Yang Release and could nullify all ninjutsu. In other words, even an Impure World Reincarnation body would
