Humberto Ramos is a Mexican Comic Book Artist born in November 1970, is best known for his work on Impulse, Spider-Man and the X-Men. He has created many of his own series including Crimson, Out There and the French publication Fairy Quest. He was trained by Oscar González Guerrero & Oscar González Loyo who introduced him to the comic book conventions held in the United States. It was at the San Diego Comic-Con of 1993 when he was discovered by Walt Simonson and introduced to Milestone Media. His first published work in America appeared in 1994's Hardware, and a year later he was introduced to a wider audience through the DC Comics title, Impulse. He followed up his success on Impulse with the first few issues of the Wildstorm team DV8, but left soon after to focus on a new project Humberto Ramos was later hired by DC Comics as the regular penciller for their Flash spin-off Impulse, which launched in March 1995. Written by Mark Waid, the superhero teen comedy series focused on young speedster Bart Allen, the grandson of the second Flash, Barry Allen, and his struggles with growing up in an alienated Alabama suburb. In 1998, Humberto Ramos co-founded the imprint Cliffhanger with comic book artists Joe Madureira and J. Scott Campbell. They created the imprint, housed by Jim Lee's Image Comics division Wildstorm, to publish their creator-owned comic books outside the mainstream superhero genre. Both Campbell and Madureira had already built large fan bases with their previous work on Gen and Uncanny X-Men respectively, and were two of the most popular comic book artists at the time. Humberto Ramos, on the other hand, was not as popular and his inclusion on the imprint was perceived as second choice, after fan-favorite Michael Turner declined because he was still under contract at Top Cow.

Humberto Ramos' first Cliffhanger title Crimson ran for 24 issues and two one-shots. It was followed by the fantasy/mystery series Out There, months later. Ramos also began illustrating the covers of Peter Parker: Spider-Man with issue #30 and—beginning with May 2002's Peter Parker: Spider-Man #44—additionally did the interior artwork on the four-issue story arc "A Death in the Family" (later collected as Spider-Man: Return of the Goblin, written by Paul Jenkins It was followed by Humberto Ramos' second Cliffhanger title, the fantasy/mystery series Out There, and a few months later.

In 2005, Humberto Ramos' creator-owned six-issue miniseries Revelations began publication by Dark Horse Comics. Following Revelations, Ramos returned to Marvel Comics to work on Wolverine starting with Issue #42. Ramos worked with writer Terry Moore on Runaways from 2008-2009, and became one of the regular artists on The Amazing Spider-Man. The distinctly Manga style artwork of Humberto Ramos has drawn polar opposite reactions from Marvel Comics fans, from those strongly favoring the cartoon style, child-like appearance of his character art, to those who were vehemently against the lighthearted and adolescent-looking artwork. The artwork of Humberto Ramos is currently credited in 710 separate Comic Book issues.
