Bernardo has been Diego’s best friend since childhood and he is now Don Alejandro’s adoptive son. Everyone sees him as the best vaquero of the hacienda and thinks he is deaf and mute. But actually, Bernardo is neither deaf nor mute, but pretending to be allows him to discover what the ennemies would like to hide…
Bernardo is not Zorro’s servant, he is his most faithful ally. He may lack Diego’s elegance but he’s got impressive physical strength in sharp contrast with his shyness. His strength and his faked conditions mean that he is considered to be stupid. Bernardo turns this to his advantage.
