Warren

Warren was a cyborg commander of both Desperado Enforcement LLC. and World Marshal Inc. His cyborg serial code is 573 52222 2617.

Early life
At some point during the late 2000s, early 2010s, Warren ended up experimented on by the Patriots, resulting in him becoming a cyborg. His left arm, in particular, was replaced with a cybernetic one, 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, Warren, alongside two heavy cyborgs, were tasked to guard the cargo freight elevators leading to World Marshal Inc.'s Headquarters building's top floor. Raiden eventually wiped him and his unit out, also taking Warren's arm for himself.

Behind the scenes
Millard 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 seventh cyborg commander in Chapter R-04, guarding the elevator area.
