The Little Mermaid AU

The Little Mermaid AU is an AU introduced through fanart, depicting the Big Four (or at least one of the characters) as mermen and mermaids. This can be considered a spinoff of Fairy Tale AU and Hybrid AU.

About the AU
This AU was formed through fanart of the Big Four (most commonly Jack and Hiccup) depicting them as merfolk or humans interacting with merfolk. Like its namesake, most writers and artists use Disney's The Little Mermaid as a template, but this is not required.

For whatever reason, this AU is most often used as a scenario for the pairing Hijack.

Hiccup Horrendous Haddock III
As a merman, Hiccup is often portrayed as having a prosthetic tail fin, as a counter part for his leg. His tail is often green in color. Toothless is most often portrayed as a shark, dolphin or orca. Hiccup would most likely have the same basic idea as he did on Berk just underwater. The dragons are often portrayed as existing sea animals, extinct sea animals or mythological sea animals. He is also portrayed as Eric from The Little Mermaid as Merida is portrayed as Ariel, because of the Mericcup pairing.

Jack Frost
Being the mysterious, magical being, Jack is the one most often portrayed as the Merman. But also as Eric from The Little Mermaid, because of Jelsa, Jarida and Jackunzel pairings.

Merida DunBroch
She is often portrayed as a mermaid, but when it comes to The Little Mermaid she is portrayed as Ariel, because of her hair, as Hiccup or Jack would be portrayed as Eric, because of the Mericcup and Jarida pairings.

Rapunzel Corona
She is also portrayed as Ariel from The Little Mermaid as Jack is portrayed as Eric, because of the Jackunzel pairing.

Princess Anna of Arendelle
She is portrayed as an average mermaid or as Ariel from The Little Mermaid, because of her hair.

Queen Elsa of Arendelle
She is often portrayed as an average mermaid, but is still allowed to have her ice powers because of the movie Frozen. Also she is portrayed as Ariel from The Little Mermaid, because of Jelsa.

Moana Waialiki
Moana's love for the ocean easily portrays her as an average mermaid, often with a red colored tail. Pua is sometimes featured as a "merpig" (a pig with a fish tail) beside her. She is also portrayed as Ariel from The Little Mermaid, as they both have dreams to explore the world beyond their home and father that wants to keep his daughter safe, at home. She can also be portrayed as Melody from The Little Mermaid 2, as they both have dreams that involve the sea. Her necklace can serve as Melody's magical locket, for its shell-like design and was given to her by a grandparent.

Maui
Maui is seen as an average merman with a shark tailfin, due to his Fish Hook acting up and turning the top part of his body into a shark's head and keeping the bottom part human; and vice versa.

The Guardians
Being mysterious, magical beings, the Guardians are easily portrayed as Merfolk. While Toothiana's Fairies and North's Yetis and Elves are existing sea animals or mythological sea animals.

In the Guardians of Childhood book series, Sandy shares his home realm with merfolk.

Mavis Dracula
Falling in love a human and having a protective single father heavily portrays Mavis as Ariel from The Little Mermaid. While being a vampire could also make her a black tailed mermaid, since there are stories about mermaids taking the lives of sailors by drowning them and with both being "creatures" that exist in stories; as well as having a human-like appearance (even when it is only the top part for mermaids while vampires have paler skin).
