The Greatest Marvel Heroes Ever

Moon Knight

Moon Knight aka Marc Spector had quite the awesome career, he enlisted in the Marines early on, and after he was done he became a field agent of the CIA. After leaving the CIA, Spector became a soldier-for-hire or rather a mercenary. During one of the missions Marc was wounded quite badly and came before a spirit of sorts and  had an encounter with Khonshu, who promised to save his life in exchange for his service, and as such gave him certain powers and thus Moon Knight was born. Marc has worked with the Avengers for some time.
