Mateo Guerrero was born in Cadiz, Spain, in 1976. Gifted with precocious talent, he soon started producing comic books for publishing house Planeta-DeAgostini. His first title with them was "Cronicas de Mesene," (1998) then "Cazadores en la red," a series he created for Idibus, a supplement for the daily El Pais. Following the example of many of his compatriots, Mateo Guerrero excels in lots of different styles, and his graphic culture draws as much on comics as it does on mangas and the Franco-Belgian school. He was rewarded for his eclecticism with a detour via the States, where he became the principle illustrator of the series "Warlords: Age of Ice," for DreamWave studio. When DreamWave was forced to close its doors, Guerrero returned to the Franco-Belgian genre, producing "DragonSeed" (2006) for publishers Humanoïdes Associés, with McClung and Jimenez. Having begun a collaboration with Le Lombard on "Beast" (2008) and then scripting and illustrating the fantasy series "Turo" (Le Lombard, 2011), he turned his attentions to the artwork of "Gloria Victus" (Le Lombard 2014, Europe Comics 2017), accompanied by Juanra Fernandez.
