Sharingan Spying Creature

This mysterious creature belonged to Shin Uchiha.

Appearance
It had four small limbs and what appeared to be a tail, an askew mouth and a nose. Its single eye featured a fully matured Sharingan.

Abilities
The creature was very stealthy, able to spy at the gate of Konohagakure without being detected. Its vision was linked to Shin Uchiha and his son's, enabling them to notice the movements of their targets. The creature could 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 could use a type of space–time ninjutsu, although it is unknown if it possessed 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 to notice the departure of Sarada Uchiha from Konohagakure. Upon seeing the vision, one of Shin's clones was ordered to capture Sasuke Uchiha's daughter. A bit later, after the clone clashed with Sarada, Chōchō Akimichi and Naruto, Shin ordered him to withdraw through the creature. Shin's clone 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.

When the Shin clones betrayed their father, Shin attempted to kidnap Sarada and Chōchō for hostage purposes, ordering the creature to take them. However, Sarada caught sight and punched the creature in the eye, killing it.
