What is the name of the villain in 'The Little Mermaid'?

The villain in The Little Mermaid is Ursula, a powerful sea witch who schemes against Ariel. In Disney’s 1989 animated film, Ursula offers Ariel a magical deal: she can become human for three days in exchange for her voice, but she must earn Prince Eric’s love before the time expires.

Ursula’s bargain is designed to fail. When Ariel begins to succeed, Ursula transforms herself into a beautiful human named Vanessa and uses Ariel’s stolen voice to enchant Eric. Her larger goal is to defeat King Triton and seize control of the undersea kingdom. The character is voiced by Pat Carroll in the original animated film.

Ursula was adapted from the sea witch in Hans Christian Andersen’s 1837 fairy tale, but Disney greatly expanded that figure’s role and made her the central antagonist. Her bold personality, tentacle design, and song “Poor Unfortunate Souls” made her one of Disney’s most recognizable villains. Scar belongs to The Lion King, while Maleficent is the villain of Sleeping Beauty.
