Solaria The Monster Carver

Adaptational Heroism: She's nowhere as genocidal as she was in canon. In fact, she barely fought monsters but was extremely invested against mewman criminals.
Adaptational Sexuality: In canon she's stated to have only one husband, though it's mostly ambiguous. She's stated to be bi here, according to one illustration.
Berserk Button: She always had a special hatred of rapists, but the sentiment grew after her sister's death.
Big Sister Instinct: She grew up protecting Melody since she was six years old. However, she was also mindful of her boundaries and respected her privacy.
Bruiser with a Soft Center: A fiercesome warrior, yes, but also honorable and loving to her family, especially her sister; she couldn't avoid crying after seen them again once she returned home from her two year pilgrimage. Hesperia composing a loving song to her also caused her to cry.
Bully Hunter: Solaria's schtick is that she's a protector of the weak: she met Dorian by defending him from bullies, her days of pilgrimage revolved around defending towns from bandits, and once she ascended she filled dungeons with thieves and rapists.
Decomposite Character: Most of Solaria's canon genocidal tendencies got passed onto her ancestor Meteora.
Does Not Like Men: After Melody's death, she developed an intense dislike for princes.
Doting Parent: Solaria was not at all disappointed Hesperia would rather be a musician than a warrior. Most likely because Hesperia took after Solaria's deceased sister Melody.
Knight Errant: In order to train herself further, she went on a pilgramage around the continent, taking up multiple military jobs.
Mama Bear: An era of peace began as soon as Hesperia was born.
She also would sent her daughter to see musical activities alongside a squad of bodyguards if she or Dorian were unavailable to go with her.
A civil war almost broke up when, thanks to a major misunderstanding, she thought Robin inpregnated Hesperia and was ready to kill the boy if it weren't for him.
