8. Ursula's Unlimited Power - The Little Mermaid (1989)
When watching an animated movie about a mermaid who falls in love with a man and has happy fish friends that like to sing and living under the sea, would you ever expect it to have a horrifying climax involving the onscreen murder of the main villain? Until the final showdown, principle antagonist Ursula is entertaining and evil, but not particularly threatening to the lives of Mermaid Arial and Prince Eric. Its shocking to see her take Neptunes crown, turning him into a wimpy brown worm, and transform into a giant sea monster that could easily have been The Krakens wife. Towering above the helpless romantic couple, it seems they have no escape as she creates a devastating storm and takes control of the sea. However, Ursula's horrific rule of the sea is cut short when Eric steers a wrecked ship toward her, and the prow of said ship impales her. The tip poking out her back is clearly visible. No wonder The Kraken was so pissed off in Pirates of the Caribbean: Dead Mans Chest.
