Mr. Madruga or also Mr. Ramón (originally Don Ramón) is one of the main characters of El Chavo, played by Ramón Valdés. Mr. Madruga appeared in practically every episode, but Valdés left the series in 1979. The character returned in 1981, in the series Chespirito. However, he left the same year and participated in the first year of Carlos Villagrán's program Ah Que Kiko! in 1987. Valdés died in 1988, putting an end to the character, who only returned in the animated incarnation of the series El Chavo. In 2025, he was resurrected by ISG, and is one of the few members of the group who does not have a malevolent personality. In any case, ISG's wealth and dark humor accommodated him.
