Continuing his run on the character, Garth Ennis used the freedom of the MAX imprint to write more realistic and hard-edged stories than had previously been seen. Ennis has stated that he would "like to see less superheroes"; this desire is reflected in the gritty, realistic tone and the anti-heroic portrayals of both the title character and Nick Fury, who made two guest appearances in the series. "Punisher" also made it explicit that Castle's timeline was fixed, while Marvel adjusted those of its other characters, with his history never altered or moved up in time. Promotional art for the cover of "Punisher" vol. 6, #44 (March 2007), gave his birth date as February 16, 1950, but that was removed for the published issues. After the departure of Ennis as writer, the series was renamed "Punisher: Frank Castle" with issue #66.
