MJOLNIR Powered Assault Armor/Black

Developed as a part of Project: MJOLNIR, the MJOLNIR Powered Assault Armor/Black variant is a standalone "skunkworks" prototype of the MJOLNIR Powered Assault Armor created by a top secret parallel development lab in Seongnam, United Korea.

Overview
While it is visually similar to the standard Mark VI MJOLNIR armor, it includes features that neither the Mark V or VI have. The HUD has a field of view of nearly five thousand meters, allowing extreme-range reconnaissance. The armor is colored jet black rather than the standard olive green, increasing the user's ability to hide in shadows. One arm includes a device nicknamed the "Interrogator", featuring a built-in microphone, processor, and speaker for translation of Covenant languages to English and from English to Covenant speech, intended for use in interrogation. The armor is capable of carrying a seventh-generation "Smart" AI, Iona. Like the Marks V and VI, MJOLNIR: Black features recharging energy shielding.

Being a prototype, it features some flaws: it has trouble displaying exact altitude, making three-dimensional tracking difficult, and the biofoam injectors were known to mistakenly set broken bones into the wrong shape to heal. The armor was used by Team Black during the Battle of Verge and during their actions on Line Installation 1-4.

Trivia

 * It is possible that the prototype Mark VI helmet that is seen in Halo Reach's Armory is the MJOLNIR: Black prototype. This is supported by the fact that its sun visor is colored black and cannot be changed.
 * The armor's visor is said to be reflective gray in Blunt Instruments, but in Halo: Blood Line, it is gold-colored like the default MJOLNIR visor.
