Spanish born illustrator, Emma Ríos, was a practising architect before she made the transition into comics. Starting off, as many do these day, by self-publishing a miniseries called A Prueba de Balas [Bulletproof]. Ríos’ self-published work and her contributions to fanzines caught the attention of Warren Ellis, who posted her work on his website, which in turn grabbed the attention of Matt Gagnon, offering Ríos a full miniseries at Boom! Studios.
That miniseres was Hexed, which was released in 2009. Now, with multiple titles under her belt, including a few for Marvel Comics (Dr. Strange: Season One, Osborn, Runaways), Ríos is working on an original ongoing series called Pretty Deadly. Published by Image Comics, the series is notable for multiple reasons, not least its all-female creative team.
