Like the previous battle, however, Apollo prevails with the help of the fire-breathing Sea Dragon.
After Ursula's fate was sealed, all the that have had been under her power, including Triton, are released from their bonds and transform back into their original forms and with Ursula and her minions gone for good, Ariel was able to return to her human form, and she and Eric were finally able to kiss for the very first time, marry, and live happily ever after.
The motivation of such practices are never exclusively revealed, though it could be theorized she held a general contempt for merfolk as a result of her banishment.
She gleefully brought shipwrecks to the surface, inadvertently providing Eric the perfect means to retaliate, without realizing his strength and skill as a sailor.
With all three outfits, she wears Ursula's golden nautilus pendant which contains Ariel's voice.
When it comes to physical powers, Ursula possesses Superhuman Strength, though not as strong as Triton, yet strong enough to throw a mermaid towards a rock, as what she did to Ariel in the alternate ending of the movie.
She fights back in the original version, much like in the film, but quickly stops when she realizes she is blowing her cover as a sweet, innocent girl.
Vanessa's role in the film is inspired by the original Andersen tale.
