MERMAID PRINCESS OF SALINIUS
Mermista
A princess of the sea who spends most of her episodes at the Crystal Falls with the rest of the Rebellion, until "The Pearl" takes her home to her father's flooding city.
Mermista is the mermaid princess of Salinius, Etheria's underwater kingdom, and a member of the Great Rebellion in the 1985-1987 Filmation She-Ra series. Her biggest episode, "The Pearl," puts her own father's kingdom at stake when Hordak steals the pearl that controls the sea.
MERMAID PRINCESS OF SALINIUS
The Rebellion's own voice from the water
Mermista's episodes cover a short window of the Filmation run, late 1985 through late 1987, and she spends most of that time at the Crystal Falls with the rest of the Rebellion's princesses. "The Pearl" is the exception, sending her underwater and putting her father's throne on the line.
"Flowers for Hordak" and "Wild Child" aired one day apart on the original broadcast schedule, and in the second she greets Adora with a warm, familiar line, "It's been a long time, hasn't it?" Nothing about either episode plays as an introduction; she arrives already settled into the Rebellion's routine.

HER BIGGEST EPISODE
Her own father's kingdom, stolen from under it
In "The Pearl," Hordak plants a spy device on an injured baby horn whale and tracks it to the sunken city of Salinius, ruled by Mermista's father, King Mercia. He steals the power pearl that gives the merfolk control of the sea and cracks the dome protecting the city, flooding it. Mermista is the one who hears the baby whale's distress call in the first place, and she is quick to answer Hordak when he shrugs off a question with "That's not my problem": "Oh, yes, it is, Hordak." At the end it is her call for help that brings the baby's mother, who wrecks Hordak's ship.
