Aoda

is the personal summon of Sasuke Uchiha.

Abilities
As a snake, Aoda is extremely fast and nimble, successfully avoiding every attack while crawling through an entire army of enemies.

Personality
Unlike some of his previous snake predecessors, Aoda seems to be very mild mannered and respectful to his summoner, as shown when he addresses Sasuke Uchiha with the -sama suffix.

Ten-Tails Revival Arc
During the second night of the Fourth Shinobi World War, Aoda was summoned alongside Katsuyu and Gamakichi by Sakura and Naruto respectively. Aoda was used by Sasuke to slide past the big clones of the Ten-Tails, in which he did with ease. While doing this, Sasuke utilized his Susanoo to use Blaze Release: Kagutsuchi on his Susanoo arrow, which he targeted the Ten-Tails with, combining it with Naruto's Wind Release: Ultra-Big Ball Rasenshuriken.
