Diego Hernández is one of the main antagonists in Season 2, along with his best friend, Ludmila, and his father Gregorio Casal. He comes from Spain, but he is currently living in Buenos Aires, Argentina. He is currently dating Francesca.

He came to Buenos Aires to look for his father, hoping that one day he can meet and get to know him, which happened at the end of Season 2, and it was revealed that his father is Gregorio.

When he first meets Violetta, he seems to have a huge crush on her and he always tries to separate León from Violetta. Later, his true character develops, and it is hinted that he is evil, just like Ludmila, who is his best friend since they were children.

But, after a time, he fell in love with Violetta and after she found out about his plan with Ludmila, she was heartbroken and broke up with him, but, Diego was heartbroken too, because he developed real feelings for Violetta.

Diego is portrayed by Diego Domínguez


Diego is a conceited, arrogant guy with a "bad boy" attitude. He's always sure about what he does, even if he knows that he could lose something. It seems like he would do anything to win Violetta's heart, but it's actually all part of Ludmila's plan. In the last episode of Season 2, his personality changed drastically when Gregorio apologized to him for not being in his life all this time and it was shown that Diego has a soft side. He also felt bad for breaking Violetta's heart, but they are now friends.
