Most of them from this new chaotic canon.

@Reval95 Agreed

Captain Phasma

Kylo Ren!

@Celestial190 agreed

Kylo Ren is a poor replacement for Darth Vader. He also reminds me of Ronan the Accuser from the Marvel Cinematic Universe.

Hux, Phasma, Vader (in Kenobi), Reva

Gunray, Snoke and Kylo Ren.

Honestly Gunray was just a greedy businessman. Basically it.

Phantom the skywing, and he's actually written clearer than any sequel villain. Or any Acolyte villain too.
