Ursula

"With Cala Maria on our side, we are ready to face off against Ursula. This wicked sea witch has no such choice but to screw us all! I'm gonna stop her."

--Su Ji-Hoon, Battle of the Atlantic

Ursula is the main antagonist of Disney's 1989 animated feature film The Little Mermaid. She is a villainous cecaelian sea witch who "helps" unfortunate merfolk to achieve her own goals. She ultimately seeks to dethrone her longstanding rival, King Triton, so that she may rule the undersea city of Atlantica, and all the ocean.

Ursula's fervent confidence, flamboyance, and theatrics have made her one of the most popular and iconic of all the Disney villains, and she quickly became one of the franchise's primary members following her debut.

In When the Cold Breeze Blows Away, she is a superweapon that has been used by the People's Democratic Union of Asia.
