Lyndon

Lyndon was a high-ranking police officer within the Denver Police Department, as well as a cyborg commander of World Marshal Inc. His cyborg serial code is 573 52210 2617.

Early life
At some point during the late 2000s, early 2010s, Lyndon 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 the Denver Police Department, acting as a peace officer since at least World Marshal Inc. took control of the privatized police department thanks to small-government legislation passed by then-state senator Steven Armstrong.

Desperado Incursions
In 2018, Lyndon, upon learning of Raiden's arrival at Denver, Colorado, as well as his intention to raid World Marshal Inc.'s HQ building, guarded an elevator in an office building that led to the rooftops, and also had two armored cyborgs on backup in case he encountered Raiden. He eventually ended up killed by Raiden, who took his arm in the process.

Behind the scenes
Lyndon 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 third cyborg commander in Chapter R-03, guarding an elevator leading up to the rooftops.
