Spawn

Summary
Spawn was once a man named Al Simmons, a highly trained assassin and was considered the best. He was a well-known soldier who was at his most successful point when he saved the President from an attempted assassination. He was promoted to a higher level of the C.I.A. that dealt with the things the Government had kept a secret from the general public. However, Al soon realized that the Government wasn't always right and started questioning if they were truly correct in their actions. This caught the attention of people in high power.
Jason Wynn who had long since been his superior found out about this and knew that Al knew too much. So he hired Chapel who was Al's friend and partner to kill him. In a blazing inferno, Al Simmons was murdered and his soul was sent to Hell because he had knowingly killed innocents in his C.I.A. days.
Al made a deal to sell his soul to a Demonic Being known as " Malebolgia" to get to see his wife Wanda Fitzgerald once again. He was allowed to come back however he came back five years later as some kind of strange Hellspawn with no memory of what he had done. After remembering what he had done, he sought out his wife only to find she had moved on and married his best friend, Terry Fitzgerald and had even had a child named Cyan.
It was after this event that his demonic guide the Violator who appeared as a clown showed up. He revealed to Spawn the purpose of his life and fought him but had his battle interrupted by Malebolgia. Now realizing his purpose he must fight to survive against both the forces of Heaven and Hell.
