Born in Madrid and currently living in London, Guillermo has been inking comics and illustrating books and magazines ever since he completed a degree in History in 2009.
On inking duties, he has worked for American publishers like Marvel, DC and Valiant, where he’s been lucky to collaborate with renowned pencillers like Jim Cheung, Raúl Allén, Emanuela Lupacchino and Jacen Burrows on titles like “Astonishing X-Men”, “Dune”, “X-Factor” and “Moon Knight”.
His first creator-owned series “The Ribbon Queen”, alongside Garth Ennis and Jacen Burrows, was published by AWA Studios in 2023, and the same team joined forces again on “Get Fury”, published by Marvel in the Spring of 2024.
