Master Chief Petty Officer John-117, or The Master Chief
Thel 'Vadam, or The Arbiter
After the end of the Human-Covenant War and the events of Halo 3, the Covenant was dissolved and the surviving aliens went back to their home planets. A radical faction of Elites, however, still believing in the divinity of the Forerunners and the Great Journey, came together to form the Covenant Remnant. It is led by charismatic Elite Jul 'Mdama, whose conniving nature later earns him an alliance with Dr. Halsey after the events of Halo 4. Under his leadership, his sect fought against the Arbiter's government on the Elite home planet and ultimately sided with the Ur-Didact as Master Chief attempted to stop him. The Covenant Remnant appear as an enemy force in Halo 5: Guardians.

Halo 5: What We Know
There are still a lot of mysteries surrounding Halo 5's story, but we do know that it will focus on two protagonists: Master Chief and Spartan Agent Jameson Locke. Both will be playable, and both will have squads of Spartans accompanying them. The game's story begins as massive Forerunner AI machines, known as Guardians, have awoken to threaten the galaxy due to the events of the Human-Covenant War, the elimination of the Flood, and the defeat of the Ur-Didact. Master Chief has gone AWOL, leaving those to question his loyalty and even his sanity when he's suspected of assassinating a human ambassador to the Elite home planet. However, in truth, this act was the fault of a human splinter group called Sapien Sunrise. But with doubts lingering, an elite squad composed of Agent Locke and Spartan-IV soldiers are dispatched to find Master Chief and take him into custody.
