Herbert

Herbert was a cyborg commander of both Desperado Enforcement LLC. and World Marshal Inc.

Early life
At some point during the late 2000s, early 2010s, Martin ended up experimented on by the Patriots, resulting in him becoming a cyborg. His left arm, in particular, was replaced with a prosthetic, containing data from the Patriots.

After the Patriots' fall, he ended up joining both Desperado Enforcement LLC. and World Marshal Inc., eventually rising up the ranks.

Desperado Incursions
In 2018, Herbert led a unit composed of Slider-equipped cyborgs, RPG-soldiers, Mastiff UGs, and RPG soldiers to storm the main lobby of World Marshal Inc.'s HQ building, after Martin's unit was wiped out by Raiden, who was raiding the HQ building to retrieve brains belonging to children. He himself utilized a Riot shield to confront Raiden, who utilized a UGT (unmanned guard tower) to hold off the unit to buy time for Doktor to hack into the (then-disabled) elevator system after the Bladewolf UG accessed the elevator server. Raiden then proceeded to wipe out his unit, also managing to remove Herbert's left arm in the process.

Behind the scenes
Herbert is a character in Metal Gear Rising: Revengeance, as well as one of thirty cyborgs to contain retrievable left arms in the game. He acted as the second cyborg commander in Chapter R-04, attacking Raiden shortly after the player first finds the elevator system disabled.
