He joined a wrestling gym in Monterrey, Nuevo León, where he was trained by Gerardo Rodríguez Pérez (Zandor wrestler), Chema López and Rolando Vera.

Guajardo thrived in the spotlight, his technical skills combined with his violent and energetic style made him one of the most hated rudos in Mexico.

For the next 13 years, Guajardo would exchange that title with Antonio Posa, Rayo de Jalisco, Aníbal, Jerry London and Ray Mendoza .

In 1967, the Rebeldes team split up violently and both men started a long feud that culminated in their famous 1968 singles bout which saw Guajardo emerge victoriously.

When the famous EMLL split came in 1974, Guajardo, Mendoza and Lagarde played an instrumental role in the newly formed Universal Wrestling Association.

His promotion company was very successful as it featured a less traditional style of wrestling that included a lot of ringside brawling and the use of bottles, chairs and illegal objects to "spice up" the matches.

During his career, Guajardo won several wager matches against famous wrestlers, such as Halcon de Oro, Ray Mendoza, Black Shadow, Felipe Ham Lee, Chino Chow, Yamamoto and Perro Aguayo.
