Born to a family of Australian-Paraguayan origins in 1944,[1] Wood spent his childhood between Paraguay and Argentina with his mother, before leaving to do various jobs, such as dishwasher, truck driver, salesman, wood chopper, journalist and factory worker in those two countries as well as in Brazil.

Anne Whitehead's 1997 book on New Australia, Paradise Mislaid, provides a chapter on Robin Wood's childhood with his extended Australian-Paraguayan family.

[2] Wood settled in Buenos Aires while working as a correspondent for Argentine newspaper El Territorio, and worked a series of unqualified jobs before he started writing scripts for popular comic book publishing company Columba.

In the 1980s Wood moved to Europe, where he continued with his writing success, especially in Italy, where he won the Yellow Kid award.

[3] Among Wood's most important works are Nippur de Lagash (1967, art by Olivera), Dennis Martin (1967), Dago (1980, Alberto Salinas), Savarese (1978, Mandrafina), Mark, Big Norman, Martin Hel, Merlin, Wolf, Gilgamesh el inmortal (Olivera), Morgan, Dax, Los Amigos, El Cosaco, Aquí la Legión, Mojado and Helena, and the humour comics of Pepe Sánchez and Mi novia y yo, both illustrated by Carlos Vogt.
