Hmm. I have a few villains 
First is Enliatu (The Dark King). He’s more the tragic villain because the power of darkness corrupted him and his family so they have all done some very bad things. Not a happy ending for him. Well, I guess that depends on the perspective.
Then there’s Tara. She’s the one who freed Enliatu in the first place. She’s basically a child throwing a tantrum about how unfair things are and eventually got slapped in the face by reality. So she’s not a permanent villain but she does disappear after her redemption.
Nephthys is just a bad person. Uhhh, trigger warning. She’s Amneris’ mother. When she found out her daughter was chosen as the next in line to hold the power of good, she basically tortured her to force-activate her powers. Eventually got banished from the God Worlds for breaking the law. She shows up again later for this whole revenge mission for the defeat of Enliatu, kidnaps her granddaughter, almost kills her second daughter, ends up having a face-off with Amneris, and then gets banished to the Void. Then she comes back again later on and ends up helping Amneris save Creation from falling into the Void. Redemption? Nope! As soon as it’s over, Amneris kicks her off the God Worlds again and says she will kill her if they ever cross paths again.
Aurelia . . . Hmm, I wouldn’t exactly classify her as a real villain, more someone with bad circumstances. See, Aurelia is from several billions of years ago and is on a mission to destroy the first Queen who just happens to have the same birth name as Amneris. Aurelia gets dragged into doing some bad things by Nephthys but eventually turns on Nephthys, swears allegiance to Xix, saves the good guys and dies a hero.
Dex is the last survivor of Ilsbrook, a city that was decimated by Amneris. He joins Nephthys and basically gets used then dumped by him.
Next is Jennix. Again, tragic villain. Jennix is from another version of Creation and was part of a mission to save their world by stealing energy from the ones the story takes place in. Gets used and played by another villain and eventually gets banished back to their Creation from people from an alternate alternate Creation. Never see them again. Never know if their Creation survives.
Then there’s Kek. He’s more an anti-hero than a true villain but he does have a five thousand year long rivalry with Amneris. They’ve been trying to kill each other since they were young. A lot of people have been caught in the crossfire. No one really knows what Kek’s ultimate plan is (except for me). Sometimes he helps the good guys, sometimes he helps the bad guys. He does what’s best for him in the moment.
Amneris could be considered a villain even though she’s one of the main heroes because she’s done some pretty nasty things throughout her life e.g., genocide, mass destruction, murder, assassination, starting wars, defying the Gods, etc etc etc
Alternate Amneris is definitely a villain. But that’s in another Creation where she got chosen to hold the power of darkness and, well, basically decimates Creation. Still working on the details for her
Then there’s the more complicated villains like Void and Darkness
This is just my main series btw
