The weekly series was published only in Mexico, non-stop for 5 years, from 1986 to 1991 (until #298).
The story deals with a group of brave variable geometry alien robots called the Transformables (also known as the Stellar Warriors) who help the powerful titular hero of the series, Karmatron (a giant super robot), battle evil forces across the universe.
The series is notable because it's considered one of the first Mexican sci-fi super robot and mecha "comic", and because of its once-per-week publication schedule, an uncommon practice at its time of release.
It is fondly remembered by many Mexicans for its unique art style and its diverse and colorful characters, all influenced by American sci-fi and fantasy works (like Star Wars, Battlestar Galactica and Transformers) as well as Japanese super robot and mecha anime shows from the 70s and 80s (Mazinger Z and Robotech/Macross).
According to the creator of the comic many foreign comic artists and authors -who published their works monthly - couldn't believe that a weekly comic was even possible at the time of publication of Karmatron.
