There are few recurring characters in the comic strips about Isidoro, and most other characters are used for individual stories. However, as Isidoro is portrayed as a dandy, many characters interact with him as if they had known each other from before. The first steady character related to Isidoro to be created was his uncle Urbano Cañones. 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. It was introduced in "The Irascible Colonel" story of the Patoruzu comic book. The first full solo story of Isidoro was a remake of this story, with Patoruzu and Upa removed from the plot. The remake introduced as well another recurring character, the captain "Metralla". Both last names, "Cañones" and "Metralla", represent military-related Spanish terms ("cannons" and "shrapnel" each), and other similar minor characters used for specific stories are named following the same recurring joke. Isidoro has a partner, named Cachorra Bazooka. In line with the aforementioned joke, she's the niece of another colonel, friend of Cañones, but which remains an unseen character during the series, used for another recurring joke where Isidoro always fail to meet or see him. 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. Other media There were attempts to make a TV series about Isidoro in the 1970s, with Santiago Bal in the main role, but were never aired. Patoruzito was featured in a pair of animated films, including Isidorito in them. The first adaption of Isidoro Cañones was done in the 2007 animated movie Isidoro: La Película, voiced by Dady Brieva and Luciana Salazar.
