Marc Worthington is a Towanda, Pennsylvania, heavyweight scheduled to make his BKFC debut against Nathaniel James on October 9, 2026, in Bethlehem. He began boxing in high school before transitioning to MMA, and describes his boxing approach as pressure-oriented and focused on entertaining fans.

His documented amateur MMA record is 3-6, with two TKO victories and one decision win. He competed for Gladius Fights and Cage Wars, including heavyweight title bouts, and stopped Mike Leverette in the first round at Gladius Fights 27. His record also includes two kickboxing appearances.

In a published interview, Worthington discussed overcoming childhood bullying and a testicular cancer diagnosis at age 14, as well as his ambition to open a gym. His employment outside fighting is not verified. Social-media searches surfaced Instagram mentions associated with C&C Management, but accessible posts did not establish reliable family or lifestyle details, so those are omitted rather than assumed.
