It is known that he was a boxer, American footballer, bullfighter, guitarist, singer, musician, master builder, etc., subjects on which he enlightens the children of the neighbourhood.

Neither has a very good relationship with Señor Barriga, to whom he always owes fourteen months' rent (fifteen, in the episode "Don Ramón leaves the neighbourhood") and therefore avoids him as much as possible, as when he comes to knock on his flat and leaves through the window without him seeing him, or sometimes distracts him with other subjects so that he does not charge him the rent, as in an episode where he says that he is going to Monterrey (Señor Barriga's favourite football team).

On occasion, however, Don Ramón tries to pay off part of his debt through temporary maintenance work in the neighbourhood, which becomes the theme of every episode (and which ends up getting him into trouble due to Chavo's meddling).

In the third season episode of El Chavo Animado, "No te vayas, Ñoño", Don Ramón is happy to hear that Señor Barriga is moving out, until Doña Florinda reminds him how good Señor Barriga has been to him for not kicking him out even though he owes him fourteen months' rent, and to scare him she told him that the new owner of the neighbourhood will kick him out.

He does not reciprocate and runs away from her, but maintains a good relationship with her, accepts gifts and food she gives him, and also scolds the children when they call her "witch".

Don Ramón's wardrobe is unmistakable, he always wears a black, green or dark grey T-shirt, with a pocket on the left side of his chest (where he kept his cigarettes), trousers, white trainers and a light blue piluso hat (just like in the animated series).

The character gained a cult status in Brazil (where he is known by the name of Seu Madruga) based on the high popularity of El Chavo del Ocho when it aired on TV in the country, most notably between the 1980s and 2010s, having been portrayed as the protagonist in memes, fangames, social media accounts, among other things, at the point where the character has spread throughout the country's pop culture.
