Aoda

is the personal summon of Sasuke Uchiha.

Personality
In stark contrast to Manda a snake of similar size to it, Aoda seems to be very mild mannered and respectful to his summoner, as shown when he addresses Sasuke Uchiha with the "-sama" suffix.

Appearance
Aoda most closely resembles an Anaconda in terms of appearance and is easily comparable in size to the largest of summons. Curiously, however, unlike most snakes, Aoda has giant holes instead of slits for his nose.

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

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.
