This month marks the release of Spawn #300, which brings the bestselling Image Comics title one issue away from becoming the single longest-running creator-owned comic book series in North America.

Ahead of its release, Image unveiled Jerome Opeña's variant cover for the milestone issue. It features a wave of different Hellspawn, those throughout history who have sold their soul to Hell in the name of vengeance, charging into battle. Among those seen on the variant are the fearsome Omega Spawn and Gunslinger Spawn from the Wild West.

Created by Image Comics co-founder and President Todd McFarlane, Spawn follows former black ops assassin Al Simmons, who sold his soul to Hell when he was murdered by his old employers. Rising as the undead antihero Spawn, Simmons finds himself defending the Earth from both supernatural and technological threats. With the publication of September's Spawn #301, the title will officially become the longest-running creator-owned title in mainstream North American comic books.

Spawn #300 goes on sale August 28 from Image Comics.
