The works that have been analyzed are symbolic names written by Carlos Fuentes, Mexican novelist, and short-story writer, critic, and diplomat whose experimental novels gave him an international literary reputation. The study deals with the analysis of the symbolic images of the name "Malinche" that appears in todoslos gatos son pardos (1970; “All Cats Are Gray”), a drama about the Spanish conquest of Mexico with the pivotal character. And "Hydra", in la cabeza de Hidra (1978; Hydra’s Head) is a mystery story, an immersion into a corrupt political world, and an exploration of different kinds of attraction between man and who deals with the subject of the search: lost identity. Therefore, we try to answer in this study some of the questions about the symbolic names in the literary text, such as:is it the name taken from the literary text we can consider as a key text. what kind of connotations it carried? How is it interpreted?.
