HRUNTING/YGGDRASIL Mark II (D) Geyrion

The HRUNTING/YGGDRASIL Mark II [D] Armor Defense System, sometimes known as the mega-Mantis, is a powered exoskeleton developed by the Materials Group. It is part of the HRUNTING/YGGDRASIL lineage, which began with the suit-like Mark I and later produced the Mark IX "Mantis". Like the Mantis, it is armed with a multi-barreled cannon on its right boom and an array of missile launchers on the other. The Mark II [D] is 19.4 meters tall.

Production note
A Mark II [D] aboard the freighter serves as the centerpiece of the Halo 4 multiplayer map Adrift. In an interview Frank O'Connor called the mech a "Cyclops Mark II", referring to the Cyclops from Halo Wars. However, Halo 4: The Essential Visual Guide makes no mention of this name. Since "Cyclops" is merely a colloquialism for the HRUNTING Mark III [B], itself derived from the third-generation exoskeleton that predated MJOLNIR, the "Cyclops Mark II" moniker was probably used only from a game-design perspective rather than having any canonical significance.
