Tsukuyomi compresses days of subjective experience into an instant of real time

Tsukuyomi compresses days of experience into an instant

Casts genjutsu through eye contact alone, including via reflections

The Sharingan tracks movement and reads hand signs as they are formed

Anticipates opponents well enough that the fights read as scripted by him

Susanoo is a defence rather than his technique of choice, which is deliberate characterisation

His eyes degrade with use, the stated cost of the Mangekyo

Izanami traps a target in a loop until they accept reality
