Superman #666

Published in 2007, Superman issue #666 serves as a notable entry in the long-running series, appearing during the 'The Third Kryptonian' story arc. Written by Kurt Busiek and illustrated by Rick Leonardi and Ande Parks, the issue explores the implications of a new, mysterious Kryptonian presence on Earth. The creative team aimed to blend traditional superhero tropes with a darker, more psychological tone, characteristic of the era's approach to established DC icons.

The decision to issue a number #666 in a major series is often treated by comic book publishers as a thematic milestone, frequently leaning into occult or darker aesthetic motifs. For this specific title, the editorial team embraced the unconventional numbering by leaning into a narrative that tests Superman's moral center. Upon its release, it was received as a stylistic departure from standard Superman fare, noted by readers for its moody atmospheric shift and the introduction of complex, ambiguous new characters.
