Unnamed Mangekyō Technique

This Unnamed Mangekyō Technique is a technique that is in every Uchiha, who has ever awakened their Mangekyō Sharingan. It allows a Mangekyō user to to put a mind controlling jutsu on any animal, thereby completely controlling it, until the technique ends, as proven when Sasuke Uchiha uses this technique to control Manda. This is also the technique that allows an Uchiha clan member with the Mangekyō Sharingan to completely control the Nine-Tailed Demon Fox, as Madara did first in his battle against Hashirama Senju, and later during the Nine-Tails' attack on Konoha. Riyan also shows that this technique can be used to repel any Nine-Tails chakra that comes within sight of the user, thus negating it's Jinchūriki's ability to form a demon fox cloak, or use Nine-Tails chakra.
There is one drawback to the technique; if the Nine-Tails is sealed within a jinchūriki, the beast itself cannot be controlled; though it's chakra, as mentioned above, cannot be used when this technique is used on it's jinchūriki.
