The character is often referenced as a "playboy", but only with the meaning of a man seeking leisure and a high-society lifestyle, without references to sex.

[1] Quinterno also created Pepe Torpedo for a comic strip in La Razón, oriented towards automovilism.

Quinterno created a new character for another newspaper, Isidoro Batacazo, a businessman interested in horse races.

Isidoro's attempts to steal money from Patoruzu or have a high lifestyle without working were the usual action that started most plots.

This character is an aged colonel that tries to force Isidoro to give up his lifestyle and find a job or develop more serious habits.

Cachorra holds a "secret identity": although she shares most of his traits, as a female version of Isidoro, she deceives Cañones, Metralla and the other military characters by posing as a reputable and innocent young woman.

There were attempts to make a TV series about Isidoro in the 1970s, with Santiago Bal in the main role, but were never aired.
