Ariel

Ariel is the princess of the underwater kingdom of Atlantica. She is originally from Disney's "The Little Mermaid". Ariel makes her debut in Kingdom Hearts. She meets Sora, Donald and Goofy when she is running away from the Heartless with Sebastian and Flounder. They teach the player how to move around in their new forms, and Sora, Donald, and Goofy cover up the fact that they are from another world by claiming that they are from a distant ocean. When she hears Goofy talking to her father about a Keyhole, she decides to help them find it and manages to find the crystal, that resembles her father's trident, that has the power to reveal the Keyhole. King Triton arrives in time to destroy it, and Ariel leaves in tears. The sea witch Ursula lures her into helping her steal the Trident from her father, with the promise of helping her get to other worlds, while also revealing that Sora, Donald, and Goofy are in fact from another world. However, things don't go as Ariel planned, as Ursula makes off with the trident and injures Triton. With Sora's help, they defeat Ursula. After sealing the Keyhole, Sora apologizes to Ariel for lying to her, but she lets it slide, confident that, if they could find a way to travel to different worlds, then so can she. In Kingdom Hearts: Chain of Memories, she appears as a memory of Sora. She roams around Atlantica though when she sees Sora and friends she runs away for no reason. Sora and co. find out she was running away because she stole her father's Trident to save Flounder from Ursula's clutches. She joins Sora's party as a Friend Card when she gives Ursula the Trident. In Kingdom Hearts II, she has an unusual role, as Atlantica sets a musical stage about Ariel and Prince Eric. She saves the prince from drowning and takes him to shore, there she sings to him until he awakes. Unable to forget about the prince, she falls into deep depression, and so Sora and the others decide to help her. When her father finds out that she has fallen in love with a human, he tries to make her forget about him by destroying the statue made with his face. But then Ursula reappears and makes a deal with her; to make her human for three days in exchange for her voice. In addition she must make the prince kiss her willingly before sunset on the third day, otherwise she will become hers forever. Despite the hardship, she signs the contract and finally gets to meet Eric in person, although he does not recognize her. On the third day, Ariel gets her voice back with Sora's help, and they all battle the sea witch again. Once Ursula is defeated, Ariel reveals to Eric that she is a mermaid and says goodbye to him, but he does not change his feelings about her. Seeing how much they are in love, King Triton finally gives in and lets his daughter be with a human prince. After the final song, "A New Day is Dawning", is sung, Ariel is depressed to learn that Sora, Donald, and Goofy are leaving, but they refuse to say goodbye and assure her in song that they will meet again. In the ending credits, Ariel is seen in human form and marries Eric.
