Mermista

Sarcastic and blunt, Mermista keeps a stony face and a cool head most of the time, usually finding it hard to express her true feelings and masking them behind a relaxed exterior. This side of her leads her to come off as arrogant, impatient, and quick to judge, as shown by her initial response to Adora’s arrival, Scorpia's speech and her attitude towards Entrapta. She is stoic and has no problem speaking her mind, but often shies away from verbally expressing her feelings, particularly the ones she holds towards Sea Hawk.

Taking charge is something Mermista is willing to do if the role necessitates, as it is she and not her father who initially greets She-Ra as diplomat of the kingdom. Once willing to, Mermista does not back away from inconvenient or difficult work, though requesting her to do undesirable jobs typically comes with some complaint. She bravely traveled the sewers of the Fright Zone to free Glimmer and Bow, albeit reluctantly. When asked to do this during the plan, she responded "Mermista will do what?" Mermista is also one for theatrics. She can be very dramatic when she gets into the role. [5]

Despite this, Mermista has begun to develop a more proactive role, including leading the Rebellion in Adora's absence. She cares deeply about her people and was visibly affected upon losing her kingdom, lamenting and stress-eating in solitude. Although a first impression might cast her as superficial, it’s made clear throughout the course of the plot that she is willing to do a lot when she puts her heart into something.

When chipped by Horde Prime, she displayed personality changes common to all chipped individuals. (See Horde Chip)
