Mjolnir Powered Assault Armor/Prefect is a Mjolnir Powered Assault Armor (GEN2) variant used by SPARTAN-IV personnel. The Prefect Armor is featured with the Champions Bundle and also can be bought separately by the Infinity Armor Pack.
Research on the Forerunner shield world of Onyx, now called Trevelyan, has cultivated numerous findings for the Office of Naval Intelligence. One of the most practical was the discovery of a native armor system, utilized by Forerunner Prefects late into their civilization’s history. The Watershed Division leveraged local Huragok to reverse-engineer the original designs, grafting the abandoned armor system into baseline Mjolnir standards for SPARTAN-IV use. It was tested at Denegroth, West Conamara on Europa.
- Aesthetically, the Prefect variant appears to have been heavily inspired by a conceptual Forerunner Combat Skin depicted in a piece of Halo 3 Concept art by Isaac Hannaford.
