Senjutsu Susanoo is an enhanced version of Susanoo created by Sasuke Uchiha by mixing the chakra that forms Susanoo with Jugo's Sage Transformation chakra. As a result, markings resembling the pattern of the Curse Mark of Heaven appear on the body of the giant chakra avatar. This form provides a significant increase in combat power compared to the regular Susanoo, allowing the use of senjutsu power while using Susanoo.
