Carlos Sanchez Ezquerra was a Spanish comics artist who works mainly in British comics He is best known as the co-creator of Judge Dredd. Ezquerra started his career based in Barcelona, drawing westerns and war stories for Spanish publishers. In 1973 he got work in the UK market through agent Barry Coker, drawing for girls' romance titles like Valentine and Mirabelle, as well as westerns for Pocket Western Library, and a variety of adventure strips for D. C. Thomson & Co.'s The Wizard. The UK was a popular market for Spanish artists as the exchange rate meant the work paid well, but Ezquerra moved to London to be near the work, settling in Croydon with his wife. In 1974, on the strength of his uncredited work for The Wizard, Pat Mills and John Wagner headhunted him, through Coker, to work for the new IPC title Battle Picture Weekly. He was asked to visualise a new character, future lawman "Judge Dredd", for the science fiction weekly 2000 AD, prior to its launch in 1977. His elaborate designs displeased the strip's writer, John Wagner, but impressed editor Pat Mills, and his cityscapes persuaded Mills to set the strip further into the future than initially intended. In 1978 he and Wagner created "Strontium Dog", a sci-fi western about a bounty hunter in a future where mutants are an oppressed minority forced into doing such dirty work, for 'Starlord'. Other 2000 AD strips he drew included Fiends of the Eastern Front (1980), a vampire story set in World War II, written by Gerry Finley-Day, and adaptations of Harry Harrison's Stainless Steel Rat novels, with the title character once again based on James Coburn. In 1982 he returned to "Judge Dredd" to draw "The Apocalypse War", a seven-month epic which he drew in its entirety. He has continued to draw the character semi-regularly, handling the whole of "Necropolis" in 1990, "Origins" in 2006-7, and many others.
