The first jutsu used in the fight between Orochimaru and Sarutobi Hiruzen is the "Reaper Death Seal" (Shiki Fujin).

The battle showcases the clash of their powerful abilities and the stakes involved.

He defected after failing to take Itachi Uchiha's Sharingan eyes. He branded Sasuke Uchiha (Itachi Uchiha's younger brother) with the Cursed Seal of Heaven in hopes of him coming to Orochimaru to find more power. He did this, and after 2 and 1/2 years of training Sasuke and Sasuke's Sharingan with Orochimaru, he prepared to steal Sasuke's body into his own so Orochimaru would have the Sharingan. He devoured Sasuke, but Sasuke's will eroded Orochimaru's jutsu (Living Corpse Reincarnation) and made Sasuke absorb Orochimaru into his body, thus backfiring the jutsu.
