Curate, connect, and discover
Does Aquaman have a similar plot/premise to Barbie in A Mermaid Tale?
Like both main protagonists are half human, half underwater creature.
Both protagonists have to fight against an evil relative. Eris the evil aunt and Orm is the evil brother.
Both protagonists go on a quest to find an item/ items to defeat evil relative. Arthur has to find the trident. Merliah has to find a comb, a dreamfish, and a necklace.
Both protagonists' mothers are "freed" from imprisonment. Atlanna wasn't exactly imprisoned, but she went missing and came back like Calissa did.
Both protagonists can talk to underwater animals. Merliah can talk to that pink dolphin and Arthur can talk to everything.
Both protagonists need to use their half human side to prove themselves. Merliah uses her human legs to climb the cliffs to get the comb and Arthur uses his powers to talk to the Leviathan.
Both evil relatives end up defeated at the end of the movie.
And probably more similarities that I can't think off the top of my head
PS: I don't consider Orm to be evil per say, but for the sake of comparison I described him as evil.
