He expects that when he returns she will be a complete woman, but she is rather now having a fish torso.

• Many comedy series, such as Family Guy and Robot Chicken, satire mermaids' inability to reproduce without genitalia.
• In the Japanese tokusatsu television subgenre (and its Americanized counterpart ), there are a few mermaid-based elements:
  • Dengeki Sentai Changeman (1985) is the design theme for the heroes of which was mythological creatures – Sayaka Nagisa (Hiroko Nishimoto) transformed into a white-colored ranger called Change Mermaid. Some of her attacks were based on underwater movement.
  • The short film Hikari Sentai Maskman (1987) features a mermaid named Lelai, who is tricked into using her beautiful singing voice to create earthquakes that would destroy the world.
  • In Power Rangers: Lightspeed Rescue (2000), Blue Ranger Chad Lee befriends and falls in love with a mermaid named Marina (Kamera Walton). She appears in only two episodes, "Ocean Blue" and "Neptune's Daughter"; the second time forced to lure the Lightspeed Rangers into a trap. (No mermaid appeared in the previous original 1999 Japanese series, Kyuukyuu Sentai GoGo-V.)
  • Mahou Sentai MagiRanger (2005) - Urara Ozu (Asami Kai) harnessed the power of the water Heavenly Saint Splagel, who is a mermaid; thus, Urara's MagiMajin form is MagiMermaid (whose legs can merge to allow her to swim underwater). However, when she upgrades halfway through the series into her Legend form, her body joins with her two older brothers and younger sister to form the Legendary Majuu MagiLion. Then in Power Rangers: Mystic Force which aired the following year, Madison Rocca (Melanie Vallejo) is the Blue Mystic Force Ranger. She draws her powers from an ancient titan who was shaped as a mermaid. Since the giant monster battle footage from PRMystic Force is taken directly from MagiRanger, Madison's giant Mystic Mermaid form mirrors that of Urara's MagiMermaid.
    • Madison's name is perhaps an intentional pun and tip of the hat since that was the name of the mermaid character played by Daryl Hannah in the 1984 film Splash.

• In the 1973-1974 anime ‘Cutie Honey’, one of Honey Kisaragi's transformations is a mermaid, which she uses to survive harsh weather conditions at sea.
