Pablo Marcos Ortega, known professionally as Pablo Marcos (born March 31, 1937), is a comic book artist and commercial illustrator best known as one of his home country Peru's leading cartoonists, and for his work on such popular American comics characters as Batman and Conan the Barbarian, particularly during the 1970s. His signature character was Marvel Comics' the Zombie, for which Marcos drew all but one story in the black-and-white horror-comics magazine Tales of the Zombie (1973–1975).
