This skin is based on the aesthetic and cyborg tech of Metal Gear Rising.
It depicts Doomguy as his own character in the MGR world rather than crossed over with any one specific character.
In this world, Doomguy is an ex-Desperado mercenary and former Wind of Destruction. His WoD title would have been "Diablo" (hot, dry, offshore wind from the northeast in the San Francisco bay) though he later goes by "Hellstorm."
