Driven, expressive, and a little hot-headed, Salem is a teenage magical girl in training who works hard to prove herself despite her short fuse. While she can be sarcastic, dramatic, and easily stressed when things don't go according to plan—especially when dealing with her rival, Gabby—she has a strong sense of determination. Beneath her tough, punk exterior, she is genuinely protective of her loved ones and deeply cares about her younger sister, Daisy, even when her annoyance gets the best of her.

Gabby is Salem’s 16-year-old kaiju rival and primary antagonist, but she is far from a typical villain. She is described as a kind-hearted, caring, and sociable girl who loves hanging out with her friends and "yapping," with the wholesome ultimate goal of becoming the best magical girl in school—despite being a giant, Godzilla-inspired monster. While she is sweet and friendly in her everyday life, Gabby takes her education and battles very seriously, turning fierce, focused, and genuinely formidable whenever it comes time to fight!

Daisy is Salem's hyperactive, playful calico kitten sister who brings pure, chaotic kid energy to the show. Armed with her oversized pink heart hammer, Daisy treats magical battles like a giant playground. She deeply looks up to her older sister and eagerly jumps into the action to help out, but her reckless enthusiasm, boundless energy, and complete lack of restraint mean her antics usually end up causing accidental, hilarious catastrophe for Salem instead.

Khloe is a competitive, aggressive, and somewhat rude giant gorilla kaiju who serves as one of the secondary antagonists fighting against Salem. Driven by her combative nature, she doesn't hesitate to throw down in battle, showing off a fierce, confrontational attitude whenever she's up against her rivals.
