Carlos Pacheco  is a Spanish Comic Book Artist and Penciller born November 14, 1962 in San Roque, Cádiz, Spain. He is best known in the United States for his work on titles such as Avengers Forever, X-Men and Green Lantern. He usually works with inker Jesús Merino. Early in his career, he did some work for Planeta-DeAgostini Comics, an imprint of pan-European publisher Planeta De Agostini. He primarily drew covers, posters and pin-ups for Spanish translated editions of Marvel Comics, published at the time by Planeta under the imprint called Cómics Forum. Carlos Pacheco first published superhero comic was an eight-page story titled American Soldier with writer and translator Antonio Moreno, and published as a back-up in Marvel Héroes #41 (May 1991). He later teamed up with writer Rafael Marín to create the characters Iberia Inc. and Tríada Vértice, two groups of Spanish superheroes, that starred in two miniseries published by Planeta-DeAgostini Comics under the imprint called "Línea Laberinto", with plots by Pacheco and Marin, script by Marin and art by Rafa Fonteriz and Jesus Merino. Carlos Pacheco first got attention in the United States for his work as penciler on Dark Guard, a Marvel UK title.

Carlos Pecheco, as a result, was offered work by American comic editors which lead to Marvel Comics in 1994 for the series Bishop. Pacheco's art had become a fan favorite, with his work regularly getting coverage in magazines such as Wizard. In early 1997 Marvel acknowledged this by assigning Pacheco to one of its flagship titles, X-Men. After X-Men, Pacheco began work on Avengers Forever, a 12-issue limited series, where Pacheco worked with writers Kurt Busiek and Roger Stern and for the first time in the U.S. inker Jesus Merino, who from that point on became Pacheco's regular inker. From 2006-2007, Carlos Pacheco worked with Kurt Busiek on DC comics' Superman, illustrating issues #654-658, 662-664, 667. Due to the difficulty to do twelve issues a year, the final chapter of the "Camelot Falls" story arc they collaborated on appeared in Superman Annual #13 (January 2008). In 2008, Pacheco produced covers for DC's weekly series Trinity, featuring Batman, Superman and Wonder Woman, and assisted artist J. G. Jones in illustrating the 2008-09 miniseries Final Crisis, on issues #4 to #6. In 2009, Pacheco signed an exclusive contract with Marvel. Carlos Pacheco is currently credited with some or all of the artwork in 417 separate Comic Book issues.
