Iwa Doctor

The doctor had an oval face with thick grey hair on the sides, but bald on the top, and a toothbrush moustache. He had narrow eyes with wrinkles under them, and creases around his mouth area. He wore a white lab coat over a dark navy turtleneck and pants, and a monocle over his right eye.

As an Outer of the secret organisation, Kara, the doctor worked under Victor in an unauthorised project to recreate the God Tree from a splinter recovered during the Fourth Shinobi World War. Wanting to elevate his own social status, the doctor proceeded with his own personal agenda by acquiring genetic material from the White Zetsu sometime after the war, in order to attain additional data for Kara's cause. One day, he approached Ōnoki, whose hopes to create artificial soldiers to replace the shinobi of Iwagakure backfired, to offer his services with the material he obtained. With it, they created the Fabrications, artificial humans to help lead the Akuta, mindless soldiers created from clay. To lead the Fabrications themselves, the doctor and Ōnoki created a Fabrication clone of the Tsuchikage himself, Kū.
