Mina Loveberry

Mina Loveberry is a famous magical warrior from Mewni and Star Butterfly's former idol who first appears in the episode "Starstruck". She serves as the main antagonist of the fourth and final season of Star vs. the Forces of Evil, leading an army of Solarian super-warriors to wipe out all monsters on Mewni. Mina is an adult female Mewman with peach skin, long purple hair tied into knee-length pigtails with large buns at each base, and green eyes. Like Star, she also has bangs that overlap her eyes. In "Pizza Party", it's revealed that before going through the Solarian program, Mina was originally withdrawn and lacking in confidence, causing her to quickly become infatuated with the strong-willed Solaria and her ideals. In "Moon the Undaunted", Mina is a tough, battle-hardened warrior type who is loyal to the Butterfly family and favors going to war with Toffee's forces over diplomacy. As seen in "Ghost of Butterfly Castle", Mina has an extreme "survival of the fittest" mentality, taking pride in being the only Solarian Warrior to survive for hundreds of years. Mina is heavily prejudiced toward monsters and upholds the long-established Mewman belief that monsters are dangerous. She carries out that belief by capturing the monsters at Star's party and trying to exterminate Meteora for being half-monster, going as far as attacking Star for defending the former and calling her a traitor for letting the captured monsters go free. Mina has a strong admiration for Solaria Butterfly and a strong hatred for Queen Eclipsa, Solaria's own daughter who advocates equal rights for monsters. In "Starstruck", Mina is portrayed as mentally and cognitively impaired, having numerous moments of irrationality and insanity. She treats living on Earth like surviving in the wild, reacts to most situations from a warrior's perspective, and briefly considers trying to rule over mankind. According to Star vs. the Forces of Evil: The Magic Book of Spells, Mina's unstable mental state is a result of the Solarian Program affecting her mind. Mina is also very confident in her abilities, but this belief leads her to become overconfident and arrogant. She briefly names herself humanity's ruler after learning they don't have one. This, coupled with her prominent insanity, can make Mina closed-minded and reckless. Even after her Solarian transformation became undone in "Cleaved" once all the magic was destroyed (and the ghost of Solaria herself silently denounced her), she stubbornly remains attached to what she believes are Solaria's ideals. Despite all these traits, Mina develops a connection with Star and calls her "Mud Sister" until she considered her a traitor for saving monsters. She later defends the late Doug-Doug from a mocking follower Solarian warrior. The only being Mina is really close to is her crow Sebastian, praising him for being the only crow not to be accidentally turned to stone in her attempt to poison Eclipsa, as seen in the end of "Junkin' Janna".
