The Little Mermaid = one of my all-time fave movies, so here's what it would be like with Terrahawks as the characters (adapting the Wikipedia description):Kate Kestrel, a mermaid princess, is dissatisfied with life under the sea and curious about the human world. With her best zeroid friend 55, Kate collects human artifacts and goes to the surface of the ocean to visit Hawkeye, who offers very inaccurate knowledge of human culture. She even misses attending a concert, at which she was meant to be the singing sensation/star. She constantly ignores the warnings of her father, King Tiger Ninestein and adviser, Sgt Major Zero, that contact between merpeople and humans is forbidden, longing to join the human world and become a human herself. Zero sings about how life is best under the sea.One night, Kate, 55 and an unwilling Zero travel to the ocean surface to watch a celebration for the birthday of Prince Hiro on a ship, with whom Kate falls in love. In an ensuing storm the ship is destroyed and Kate saves the unconscious Hiro from drowning. Kate sings to him, but quickly leaves as soon as he regains consciousness to avoid being discovered. Fascinated by the memory of her voice, Hiro vows to find who saved and sung to him and Kate vows to find a way to join him and his world. Noticing a change in Kate's behavior, Tiger questions Zero about her behavior and learns of her love for Hiro. Tiger furiously confronts Kate in her grotto, where she and 55 store human artifacts, and destroys the objects with his trident. After Tiger leaves, a pair of hissing cubes, Flotsam and Jetsam, convince Kate to visit Zelda the sea witch.Zelda makes a deal with Kate to transform her into a human for three days in exchange for Kate's voice, which Zelda puts in a nautilus shell. Within these three days, Kate must receive the 'kiss of true love' from Hiro; otherwise, she will transform back into a mermaid and belong to Zelda. Kate is then given human legs and taken to the surface by 55 and Zero. Hiro finds Kate on the beach and takes her to his castle, unaware that she is the one who had saved him earlier. Kate spends time with Hiro, and at the end of the second day, they almost kiss but are thwarted by Flotsam and Jetsam. Angered at their narrow escape, Zelda takes the disguise of a beautiful young woman named "Mary Falconer" and appears onshore singing with Kate's voice. Hiro recognizes the song and, in her disguise, Zelda casts a hypnotic enchantment on Hiro to make him forget about Kate.The next day, Kate finds out that Hiro will be married to the disguised Zelda. Hawkeye discovers that Mary is Zelda in disguise, and informs Kate who immediately goes after the wedding barge. Zero informs Tiger, and Hawkeye disrupts the wedding with the help of various animals. In the chaos, the nautilus shell around Zelda's neck is broken, restoring Kate's voice and breaking Zelda's enchantment over Hiro. Realizing that Kate was the girl who saved his life, Hiro rushes to kiss her, but the sun sets and Kate transforms back into a mermaid. Zelda reverts to her true form and kidnaps Kate. Tiger confronts Zelda and demands Kate's release, but the deal is inviolable. At Zelda's urging, he agrees to take Kate's place as Zelda's prisoner. Kate is released as Tiger transforms into a polyp and loses his authority over Atlantica. Zelda declares herself the new ruler and quickly grows to monstrous proportions.Kate and Hiro reconcile on the surface just before Ursula grows past and towers the two. She then gains full control of the entire ocean, creating a storm with a maelstrom and shipwrecks, one of which Hiro commandeers. As Zelda attempts to destroy a trapped Kate in the maelstrom, Hiro turns the wheel hard to port and runs Zelda through the abdomen with the ship's splintered bowsprit, mortally wounding her. After her death, Zelda's power breaks, causing Tiger and all the other polyps in Zelda's garden to revert back into their original forms. Later, after seeing that Kate truly loves Hiro, Tiger willingly changes her from a mermaid into a human. An unspecified amount of time later, Kate and Hiro have their wedding on a ship and depart.I'll probably do this for Starfleet too; but Terrahawks = a slightly better match, because Kate and Ariel = both renowned for their singing voices.
