Buena Girl is the deuteragonist of ¡Mucha Lucha!
She is voiced by Kimberly Brooks.
She lives by every rule of The Code of Masked Wrestling, which she uses as guidelines for the Mascaritas' actions and behavior. Despite her cuteness and beauty, she has a by-the-book personality, which often causes friction between her and her friends. She is usually kind but can be obnoxious and arrogant at times. She seems to have a crush on Rikochet and really admires him.
She does have moments of lacking common sense. For example when she, Rikochet and the Flea ended up marooned separately on island, she decided to recreate a civilized environment for herself. In sheer idiocy, she recreates the classroom environment and decide to get to "Buena learning" even though there was nothing to do; rather than proper living space to survive in. After staring at nothing for a long time, she snapped and started hearing her Code book start talking to her.
Her signature move is the "Buena Bulldozer Of Truth", where she shape-shifts into a powerful bulldozer with sharp teeth that can scoop up many opponents at once and carry them out of the fighting ring.
Normally, Buena Girl remarks, "It's not right!" when something goes against the Code of Masked Wrestling or anything outside the school rules. She also alternates the Spanish buena in place of its English counterpart, good in some sentences.
