Yes Man

Yes Man is an AI unit that serves as Benny's assistant in 2281, and is an integral part of Benny's scheme to take control of New Vegas. He initially inhabits a PDQ-88b Securitron. He later can assist the Courier in the "independent" option of the game's ending.

Background
Yes Man was originally a generic Securitron robot working for Mr. House, like all the other Securitrons found on the Strip. He was damaged by a pulse grenade, and was recovered by Benny and the Chairmen, who then allowed Emily Ortal to examine the Securitron for Mr. House's secrets, in exchange for reprogramming him.

The reprogramming was extensive, and resulted in Yes Man being designed to do exactly as he is told (although the lack of restrictions as to who is doing the ordering would later be Benny's undoing). The plan was to dispose of Mr. House, plant Yes Man's A.I. in the Lucky 38 mainframe which would then put him (and by extension, Benny) in control of all the other Securitrons on the Strip. The next step was to take the platinum chip to The Fort, where he would take control of whatever great weapon he suspected Mr. House to have hidden away (as he did not know exactly what was stored there). The last step in the plan was to use this "weapon" to assume control of New Vegas and Hoover Dam.

Yes Man is abandoned when Benny flees to the Fort after the Courier pursues him to the Tops, and is soon after found by the Courier.

Yes Man can also be found after Benny has been assassinated by the Courier at The Tops.

 * Wild Card: You and What Army?: The Courier must travel east of the Colorado River to The Fort and activate an army of Securitrons locked away in House's secret Securitron vault.

 * Wild Card: Finishing Touches: The Courier must convince Julie Farkas to support an independent Vegas, (optional) protect President Kimball against an assassination attempt and use an override on the El Dorado Substation in order to power the Lucky 38 and allow it to broadcast the Securitron operating system upgrade.
 * No Gods, No Masters: The Courier must power up the secret Vault, allowing the Securitrons within to break out and crush the Legion, before convincing the NCR to leave the Dam to Vegas - by force, if necessary.
