[2] He later studied at the Chilean School of Applied Arts, where in his spare time he created his first original characters, Ferrilo the Robot and Homero the Pilot.
He was later signed on to work as one of the assistants to Guido Vallejos on the famous Chilean comic-book Barrabases, where he created the characters Cicleto, Cucufato and Ñeclito.
For this magazine he introduced his first truly popular creation: Alaraco, a comic strip about an over-concerned and overreacting man (modeled on Lobos' own personality).
It tells the story of a young Chilean boy who obtains a "space-time belt" and uses it to travel through time, seeking to experience history's greatest adventures.
[5] Mampato and the whole Chilean comics industry were affected by the 1973 coup d'état against Salvador Allende's government, led by Augusto Pinochet on September 11.
Some people took issue with certain stories such as Los Tres ("The Three"), aka El Árbol Gigante ("The Giant Tree"), where Mampato fights mutants ruled by a character called Ferjus, the leader of a tyrannical dictatorship.
In 1983, the Chilean TV show Jappening Con Ja staged a live-action sketch of his comic strip, Alaraco, starring comedian Fernando Alarcón.
In 1996, Ediciones Dolmen began its publication of Mampato's adventures in the comic album format, with recolored art and new covers, which have been sold in South America and Europe.
