Sharingan Spying Creature

This mysterious creature belongs to Shin Uchiha.

Appearance
It has four small limbs and what appears to be a tail, an askew mouth and a nose. Its single eye features a fully matured Sharingan.

Abilities
The creature is very stealthy, able to spy at the gate of Konohagakure without being detected. Its vision is linked to Shin Uchiha and his son's, enabling them to notice the movements of their targets. The creature can also act as a verbal communication medium, seen as Shin received orders from his father through it. By taking on the form of Shin's Mangekyō Sharingan, the creature can use a type of space–time ninjutsu, although it is unknown if it possesses this ability itself or if it acted once again as a medium.

Naruto Gaiden: The Seventh Hokage and the Scarlet Spring
The creature was used by Shin Uchiha's father to notice the departure of Sarada Uchiha from Konohagakure. Upon seeing the vision, Shin was ordered to capture Sasuke Uchiha's daughter. A bit later, after Shin clashed with Sarada, Chōchō Akimichi and Naruto, his father ordered him to withdraw through the creature. Shin and the creature then flew by using space-time ninjutsu. Later, when its master was ready to begin another attack, the creatures teleported him and six copies of Shin to Naruto and Sarada.
