King Cosmos

King Cosmos is the former tyrannical king of Equestria, Princess Celestia and Princess Luna's abusive father, one of Equestria's escaped convicts, the overarching antagonist of the series My Little Pony: The Shadows, and the main antagonist of My Little Pony: A Royal Origin.

Backstory

Not a whole lot is seen about King Cosmos's backstory, but it was known that he had a tough childhood due to his father abusing him physically and mentally. He hired Chrysalis, Tirek, and Cozy Glow to attack Equestria, and overthrow King Sombra's father, King Terra. He also murdered his ex-wife Queen Galaxia, and abused Celestia and Luna a lot when they were young. Years later, Cosmos made an unexpected visit to The Shadow Kingdom and threatened Sombra to give the royal sisters back to him, or he would've died, therefore he kidnapped Celestia and left her severely beaten, some time later, the police came by, and the crimes he committed were discovered, leading up to Cosmos being dethroned and arrested.

Personality

King Cosmos is shown to be very selfish, abusive, power-hungry, and murderous. He was never a good king, all he cared about was his abuse of power and never focuses on anyone else but himself. This leads up to King Cosmos corrupting Equestria and making it fall into eternal darkness, and making it nothing but a wasteland.
