First appearance: Mysterious Seven Project

Master Chief, also known as John-117, is the main protagonist of Microsoft's Halo franchise. He is a member of the Spartans, a squad that works for the United Nations Space Command (often abbreviated as UNSC) to protect the galaxy.

Master Chief has gone up against the Covenant and the Flood, as well as their ancestors known as the Forerunners. No one has ever seen the visage under his helmet; however, he is known as a hero to the UNSC.


The Mysterious Seven Project

Chief appears in this game as a hidden character, as well as a prominent character in Binary Time. In the latter, Chief arrives in the Mysteriousverse via thumb drive to investigate the mysterious giant coins falling out of the sky. He knows more about these coins than even Nick Fury and the Mysterious Five Organization.
