The Fourth Hokage's Death Match

Kushina delivers Naruto, but the moment turns to horror when Tobi kills the midwives Biwako and Taji and seizes the newborn. He fixes explosive tags to the infant and throws him skyward, forcing Minato to catch the baby, tear off the tags, and teleport clear with his Flying Thunder God Technique. Tobi exploits the opening, using Kamui to whisk Kushina away, where he draws the Nine-Tails out of her and takes command of it with his Sharingan, aiming it at Konoha. Minato stashes his son in one of his safehouses, warps back to rescue Kushina from the beast by way of the seal marked on her, and returns her to the child before donning his Hokage garb.

In the village, Guy badgers Kakashi for another contest as Tobi slips inside and summons the Nine-Tails to run wild. Hiruzen, Chōza, Shikaku, and Inoichi rally to the defense. Minato arrives, and when the fox launches a Tailed Beast Ball at him, he redirects it to safety with Flying Thunder God: Guiding Thunder. He is drawn into a duel with Tobi, evading a Kamui attempt at the last instant, and after Tobi praises his teleportation, Minato deduces that a Sharingan strong enough to dominate the fox and breach the village unseen could only belong to Madara Uchiha, though he dismisses the idea since Madara should be long dead.

Tobi's intangibility keeps Minato's blows from landing, so Minato hurls a Flying Thunder God Kunai at his head and charges. As the kunai passes through, Tobi materializes to grab him, but Minato forms a Rasengan, teleports to the blade behind him, and lands the strike, branding him. Tobi's left arm begins to crumble and fall away. With his mark placed, Minato instantly warps to Tobi and applies a Contract Seal, wrenching control of the Nine-Tails away from him.

The episode adapts chapters 500 through 503. Team Tobirama and Torifu Akimichi, present in the manga version, are absent here. Minato's glare at the fox and Tobi is repositioned relative to the manga, occurring when Kushina names Tobi's goal as Konoha's destruction. The Sharingan shown as Tobi uses Kamui is a standard eye rather than the Mangekyō, a continuity slip carried across earlier episodes, and the peeling of Tobi's left arm is another error, since that arm was his original while the right was artificial.
