Today’s revealed variants are for some of Image Comics’ biggest series, and include “Seven to Eternity,” “The Old Guard,” “Rose,” “Horizon,” "Regression” and “Manifest Destiny.” Each cover depicts and artists' unique spin on their respective franchises mashed up with the demonic hellspawn protagonist of Todd McFarlane’s “Spawn” series.

“Spawn” was one of the earliest series published by Image Comics after the company was founded in 1992. The series’ first issue sold over 1.7 million copies, providing legitimacy for the company that was formed by a coalition of comic book writers, artists and businesspeople set on emphasizing creator-owner works.

Image Comics’ 25th anniversary is a yearlong event. The publisher has been celebrating with monthly themed variant covers since the company’s official anniversary back in February. February brought variants celebrating iconic covers throughout the company’s history. March’s themed variants coincided with Women’s History Month; cover art focused on women’s careers in the comic book industry and all proceeds were donated to Planned Parenthood. April’s variants were April Fools-themed and drew inspiration from contemporary comic book covers from across the industry.

“Spawn” tells the story of Albert Francis Simmons, a CIA operative who is murdered by his friend and fellow agent. Simmons is subsequently sent to Hell for his role in the murder of innocents while on the job. Instead of suffering an eternity of torment, though, he is recruited by the demon Malebolgia to become a superpowered member of Hell’s terrestrial army, a Hellspawn.

The series was created by Todd McFarlane, who gained notoriety throughout the ‘80s and ‘90s for his work as an artist on the “Spider-Man” comics series. He left Marvel to found Image Comics along with Jim Lee, Whilce Portacio, Marc Silvestri, Erik Larsen, Jim Valentino and Rob Liefeld.
