Horde Prime (She-Ra and the Princesses of Power)

You have forgotten who you are. You truly think you are worthy to stand beside me, could be EQUAL to me? I made you in my image, but you have become an abomination. And so, you must be reborn.
„

~ Horde Prime to Hordak before wiping the latter's mind.

“
You miscalculated. I see all. I know all. You thought yourself worthy to challenge me, but you are nothing but a false hero, the last of the First Ones to fall at my hands. You have led your friends to destruction.

What Makes Him Pure Evil?
In General/Background
He is basically responsible for every event that happened in the series.
He's the only villain in She-Ra and the Princesses of Power that doesn't have any redeeming qualities.
He created the Galactic Horde where he and his clone army conqueror and destroy planets and galaxies across the universe.
He waged war against the First Ones, eventually wiping most of them out.
Casts his top general, Hordak, out through a portal to Etheria for having an error with his cloning
This caused Hordak to build his empire to prove he was not defective, making Prime indirectly responsible for the Horde’s actions on Etheria.
Season 5
After Hordak had done everything to impress him, he is not impressed when he comes to Etheria and sends Hordak off to be reconditioned, which involves horrible mindwipes.
He planned to destroy Etheria to cover up Hordak's failure and is only convinced otherwise when Catra tells him about the Heart of Etheria.
He conquers Etheria with absolutely no effort or mercy.
He uses the dining room's giant monitor screen to show Glimmer footage from his army's attack on the Rebellion's base.
He then threatens to kill them all unless Glimmer gives him the information he wants. Glimmer, not wanting her friends to get hurt, gives in to his threats, and Horde Prime-only orders his soldiers to stand down because he finds out from Glimmer that Adora/She-Ra is the only one capable of controlling the Heart of Etheria.
He shows Glimmer his trophy collection, which shows a trophy he took of every planet he conquered, destroyed, and reshaped in his image.
He tries to convince Glimmer to help him find She-Ra by claiming that he only wants to use the Heart of Etheria to create peace. Glimmer tells him that activating the Heart could potentially wipe out all life in the universe, only for Horde Prime to reveal that it's precisely what he wants so he can rebuild the universe in his image.
When one of the clones is given a name at this point, Horde Prime has him melted down to free him from the curse of individuality, with the others chanting how his Light purifies them all, as it was shown with Hordak when Catra reminds him of his name.
He brainwashes many people to fight on his side with no qualms by using mind control chips to turn people into drones similar to his clones and, subsequently, turn them against their friends.
He attempts to use the Heart of Etheria to destroy the entire universe and remake it in his image.
He treats his clones horribly, viewing them as slaves at worst and extensions of himself at best.
He also wouldn't allow them to have emotions and freedom rights, as shown when he was enraged upon finding out that Hordak has a name and found a purpose in his life before mind-wiping him.
After he is thrown down the shaft by Hordak, he possesses and later uses him as his vessel and decides to take Entrapta with him and use the Heart of Etheria to destroy the universe permanently, himself included.
He's indirectly responsible for the death of Shadow Weaver, as she sacrificed herself to save Adora and Catra from the First Ones' monster he controlled.
He orders Hordak to kill Entrapta.
While he pushes the idea of bringing peace, it's nothing more than his twisted version of it.
His decision of sending Hordak on a suicide mission also lead to the exile of King Micah and sacrifice/death of Queen Angella, Glimmer's parents, with the Queen not knowing her husband was alive.
When he was confronted by She-Ra after his plans had failed, he still doesn't want to give up or show remorse for his crimes and he just proclaims his invincibility and promises to rise again. But She-Ra then exorcizes Hordak to free him from his presence and finally kills him.
