Buena Girl - Among El tres Mascaritas, Buena Girl is the most knowledgeable 9-year-old on The Code of Masked Wrestling, which she uses as guidelines for the Mascaritas' actions and behavior, a secondary protagonist, and a heroine. She is a stickler for the rules, which often causes friction between her and her friends. 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. She was voiced by Tress MacNeille.
