Gotta

is a member, and seemingly default leader of the Iburi clan.

Background
As a member of the Iburi clan, Gotta seemingly lived in hiding with the rest of his clan until Orochimaru discovered them. Using the cursed seal to stabilise their abilities, he manipulated the clan into giving him their children for the purposes of his experiments. He now seemingly heads the clan in the absence of either Orochimaru or Danzō.

Personality
Gotta appears to be very loyal to Orochimaru for saving his clan, willing to conceal him despite being a fugitive from Konohagakure and willing to kill any pursuer.

Appearance
Gotta has short black hair and dons a short, two-parts mustache. He wears a simple, gray vest, dark gray pants and sandals.

Abilities
Gotta, like the rest of his clan, has the ability to transform into a living smoke that can still interact physically with other objects, such as picking up scrolls.
