Sukuna

A Heian Era sorcerer, he was once known notoriously as the King of Curses and legended as the greatest Sorcerer to ever live. Sukuna is "less of a sorcerer and more of a walking disaster." Sukuna was created as a cruel, narcissistic, depraved and supremely arrogant figure. Sukuna's fantasized physical figure has four arms and a malicious demonic personality. Sukuna will kill anybody in an instant and he has no morals.
