black frieza
First appearing in the manga version of Dragon Ball Super, it is a black, silver, and purple-colored power-up form achieved by Frieza after he trained for 10 years inside a Hyperbolic Time Chamber on a planet he conquered. Not only this form is very much superior to his Golden Frieza form, it is also very powerful enough for Frieza to easily defeat both Ultra Instinct Son Goku and Ultra Ego Vegeta in a single blow.
