Violetta "Tini" Castillo is the female titular protagonist of Disney Channel's original TV series, Violetta. She is a beautiful, smart and passionate young girl, but is sometimes held back by her very overprotective father, Herman Castillo. She is musically gifted and has a wonderful and unique voice that she inherited from her mother, who tragically passed away in a bus accident when she was 5 years old. She is the girlfriend of Leon Vargas. When Violetta first returns to Buenos Aires, she discovers her passion for music and begins to attend Studio 21 (now On Beat Studio) despite her father's disapproval. It is there that she makes her first friends and learns more about herself. She meets two very different boys, Tomás and Leon, who fall in love with her. She becomes entangled in a love triangle with them and has trouble deciding who she truly loves. Through her journey, Violetta realizes that music means everything to her and that singing is what she wants to do with her life. Knowing that her father would not accept her, she hides everything from him out of fear which only further complicates their relationship. By the end of season 1, she learns to be honest and true to herself, gaining her father's approval. Violetta is portrayed by Martina Stoessel.
