and Gobots the publisher requested Gonzalez Loyo to include characters of this type in the comic book, so finally the series would be renamed Karmatron y los Transformables to increase sales. The series was finally published for the first time in February 1986, in a weekly format and until mid 1991. Each comic had 32 pages and the whole original series from the eighties lasted 298 issues. Each comic of the classic eighties series was made completely in one week, but sometimes past numbers were re-edited and relaunched or substituted by issues with great amounts of text to be able to complete its weekly schedule deadline. The creator of the series claims that during the 5 years of its publication the comic managed to have more than 100,000 comics sold. However, there is no registry or any other information to confirm such numbers. In 1992 a new reboot edition was released in a black and white graphic novel format with redesigned characters, but this was a special limited series that lasted just a couple issues. In December 2002 the comic series was again remade entirely by ¡Ka-Boom! Studio with a modified storyline, new art, improved modern digital coloring, new designs and a bigger, more standard comic book size format. The release schedule of each issue for the new reboot series has been extremely irregular with comics released after 2 months or up to a 1 year hiatus. So far 20 numbers have been published, with the latest issue released in late 2017. Crossovers Because of the title's popularity during the eighties, several issues included crossovers with popular characters from other Mexican independent comics of the same period. Numbers 100 to 104 of the original series -published in 1988- included a crossover called "Karmatrón vs Destrúktor" with several characters from Destrúktor, El Defensor Cósmico (Destruktor, The Cosmic Defender), another popular Mexican science fiction weekly comic from 1987 that lasted 33 issues and was drawn by artist Nicanor Peña Cabrera. From number 284 to 286 -published in 1991- another crossover called "Aventuras en el Planeta Tier-rata" (Adventures in Planet Earth-Rat or Adventures in Planet Terrat) took place, where the protagonists were Jiva and Robby (Karmatron sidekicks and comic relief characters from Oscar González Loyo) as well as Visitor Zot and rats Fulano, Zutano and Mengano (from an indie comic by artist and author Francisco "Paco" Baca).
