Susanoo Genjutsu

Using his Sharingan, Sasuke stares at his opponent directly in the eye. Then a shadowy figure of himself appears before them forcing them under a genjutsu. An image resembling his Susanoo appears in front of the opponent and grasps them as it begins "assimilating" them into itself. This breaks the opponent's will. Afterwards, the opponent is left incapacitated.

Trivia

 * This genjutsu seems to cause strain to the user similar to Tsukuyomi as Sasuke was seen covering his left eye in pain after the genjutsu ended. In fact, is is quite possible that this genjutsu was Tsukiyomi.
 * Sasuke's completed version of Susanoo was first seen in this genjutsu, though as a shadowy figure before completely debuting in the fight against Danzō.
