First appearance: Spawn #187.
Marc had been the blotter page writer at the New York Clarion for 6 months, but he had aspirations for more. He desperately wanted to move up to a feature writer but his boss, Mr. DeLeon, wasn't interested. Luckily for Marc, the explosion that destroyed St. Anthony's Hospital provided a huge opportunity to prove himself as a journalist.
Feeling trapped and aimless, Marc began toying with the Medieval Spawn armor that they had been researching. In doing so, he was suddenly engulfed in a green power and knocked unconscious (Spawn #312).
