Majestic Attire: Susanoo

The user shapes their Susanoo into an armour for Kurama, enhancing its defence and preventing its chakra from being suppressed. Kurama can wield Susanoo's bladed weaponry as well as combine it with its own Tailed Beast Balls to give the latter cutting power, making them impossible to catch.

Trivia

 * In adulthood, Sasuke retained the ability to manifest a partial armour similar to the form his Complete Body — Susanoo took after it absorbed the Tailed Beast chakra.
 * In Naruto x Boruto: Ultimate Ninja Storm Connections, Merz was able to copy this armour of Susanoo with his artificial Mangekyō Sharingan without the need for Kurama. This version instead has dark flames on its back that resemble tails.
