Among the Three Mascaritas, Buena Girl is the most knowledgeable 10-year-old on The Code of Masked Wrestling, which she uses as guidelines for the Mascaritas' actions and behavior, a co-protagonist, and a heroine. She is a stickler for the rules, which often causes friction between her and Rikochet. She brushes her teeth eight times a day (could be considered Obsessive Compulsive Disorder.) Her signature move is the "Buena Bulldozer Of Truth", where she transforms into a bulldozer. She claims to be a descendant of the Slamazons, an ancient tribe of female masked wrestlers (play on the Amazons). Normally, Buena Girl remarks, "That's not right!" when something goes against the Code of Masked Wrestling or anything outside the rules. She also alternates the Spanish buena in place of its English counterpart, good in some sentences. Her parents are very cheery. also She has a secret crush on Rikochet. She was voiced by Kimberly Brooks.
