Barack

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

Early life
At some point during the late 2000s, early 2010s, Barack 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, Barack and several cyborgs ambushed Raiden, after the latter survived falling from Doktor's helicopter while trying to save his chopper during their escape with several brain canisters from World Marshal's HQ building at Denver, Colorado. He and his unit were ultimately killed by Raiden, with Raiden taking Barack's arm in the process.

Behind the scenes
Barack 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 first cyborg commander in Chapter R-05, as part of the cyborgs that instantly ambush Raiden shortly after Boris contacted him to escape from Denver on foot at the start of the level.
