Author's Note: This is basically the story of Maleficent (live action) but PotC style.
Narrator: Once upon a time, there was a young siren named Angelica, who lived peacefully with her people. She wondered about the world around her, for all she had ever known was Whitecap Bay, the home of all mers.
(Title flashes)
Young Angelica: Hello Marina, Syrena, and Tarina! You're looking well!
Marina: Well thank ye, darling.
Tarina: We ought to tell her.
Marina: Very well. Angelica, the-
Syrena: The mermen have found a human at the chalice cove!
(Angelica swims as fast as she can to the spot where the human was to be.)
Angelica: What's your name?
Boy: Weatherby. Weatherby Swann. What's yours? And why do you have a tail.
Angelica: I'm Angelica. I have a tail because I'm a mermaid. Give it back.
Edward: Give what back?
Angelica: The tear you took.
Edward: Fine.
Narrator: Weatherby and Angelica talked for awhile, and found that they enjoyed each other's company very much. Eventually they became friends, and later, even more.
Weatherby: Angelica!
Angelica: I'm here.
Weatherby: I have a present for you, I know you're turning sixteen.
Angelica: (blushes)
Narrator: Weatherby called it true love's kiss. But as the years blew by, Weatherby was allured by the kingdom and its riches, and spent less time with Angelica. But the once timid mermaid now was the protector of her kind. But King Barbossa saw a growing power in Whitecap Bay, and he sought to strike it down.
Angelica was aware of the pounding footsteps of the men drawing near, and did her best to not think about Edward.
King Barbossa: None dare to enter the mysterious Whitecap Bay, for fear of the magical creatures that lurk within. Well I say, crush them!
Scrum: Even da pretty ones?
King Barbossa: Yes idiot, even the pretty ones.
Pintel: Aww.
Angelica: You shall not have Whitecap Bay, now or ever!
King Barbossa: A king does not take orders from a fish with a face.
Angelica: You are no King to me!
Army: For the King! Rah!
Angelica: (summons her friends)
Seahorse: Roar!
Army: AHHHHH! (Runs away, cut to the king's bedroom)
King Barbossa: I promised the people when I ascended to the throne, that I would take Whitecap Bay. I see you all waiting for me to die, it won't be long now. Kill the creature, and whoever does, takes the throne and marries my daughter.
Edward: Oh no... Angelica!
(In WB)
Edward: Angelica!
Angelica: I'm here.
Weatherby: Angelica they mean to kill you you gotta trust me!
Narrator: And so Angelica and Weatherby spoke, and things were as they had been long ago. Weatherby offered Angelica a drink for her parched throat, and she accepted. What Angelica did not know was it was a sleeping potion. But Weatherby knew.
Weatherby: Angelica? Angelica I gotta take you to the King I'm sorry...
Narrator: But Weatherby could not kill his love, so he instead cut off her tail, forcing her to grow human legs.
(The next morning)
Angelica: Ahhhhhhhhhhhhhhhhhhhhh! Ahhhhhhhhhhhhhhhhhhhhh!
(Goes to the abandoned castle.)
Angelica: He-he... Ahhhh.
(Hears thrashing)
Davy Jones: Ha! They don't call me Agent of Death for nothing! I gotcha, crow!
(Angelica magically turns the crow into a human)
Jack S: What 'ave you done to me dashing self, lass?
(In the Castle)
King Barbossa: You have killed her?
Edward: The deed has been done.
King Barbossa: You will be a fine successor.
Edward: I will do my best.
(3 years later)
Maids: Oh it's a girl!
King Weatherby: Hello my people. My wife and I have a child. Her name is Elizabeth.
(Doors whoosh open)
Angelica: Hello Weatherby.
King Weatherby: You are not welcome here.
Angelica: Oh. What an awkward situation!
Elizabeth's Unnamed Mother: And you're not offended?
Angelica: Why, no. In fact, to show that I bear no ill will, I shall bestow a gift on the child.
