Orochimaru's Death

Being one of the Legendary Three Ninjas as well as a former member of Akatsuki, and hailed by his sensei Sarutobi as a natural genius, Orochimaru is a powerful ninja, being able to fight on an equal footing with a four-tailed demon fox form Naruto Uzumaki in Part II, and despite the danger Naruto imposes, he finds the battle highly entertaining. While he has only displayed a limited amount of techniques, it stands to reason that his efforts to learn all existing jutsu has made his array of abilities vast.

As a byproduct of his research to gain immortality, Orochimaru learned the forbidden technique Summoning: Impure World Resurrection (口寄せ・穢土転生, Kuchiyose: Edo Tensei, English "Summoning Jutsu: Reanimation"), which allows him to revive the dead.

Orochimaru has an apparent interest in snakes that, in addition to impacting the appearance and composition of his true form, has caused him to learn a number of snake-related abilities. One such ability is being able to summon giant snakes to fight alongside him in battle, made possible by the summoning contract tattooed to his left arm. Orochimaru can also call forth snakes from his sleeves and mouth to attack opponents in large numbers with poisonous bites. Another usage of snakes comes in the form of his Kusanagi Sword (草薙の剣, Kusanagi no Tsurugi).
