Spawn is a fictional comic book character created by Todd McFarlane. Spawn primarily appears in a comic of the same name, published by Image Comics, and his first appearance was in Spawn #1 (May 1992). The religion-heavy book began with a very superhero-like tone, much like McFarlane's previous work, but the title character evolved into a more flawed anti-hero.
The current book has skewed significantly darker than early issues would suggest. McFarlane attributes this to being a necessary part of development. To introduce the book to readers it had to be slightly cleaner than he really wished it to be so that it read like a superhero tale.
As the book took off and became more established he was able to alter the tone closer to his vision. An African American CIA agent killed by his own boss for witnessing his corruption, Al Simmons was sent to hell. To see his wife one more time, he made a deal with the devil Malebolgia to become an undead "hellspawn".
Spawn has tried to retain his own humanity while finding a way out of Malebolgia's control and battling a variety of enemies, both supernatural and criminal.
