Yes Man

 is a securitron robot found in the Mojave Wasteland in 2281. He serves as Benny's assistant and can't help but reveal the end game scenario for New Vegas in excruciating detail. He was programmed by a member of the Followers of the Apocalypse to answer all questions that he was able to answer and assist in any way he can, but was never given any restrictions about who would be able to ask him questions in the first place, allowing him to help the Courier.

Background
Yes Man was originally a generic securitron robot working for Mr. House, like all the other securitron found on the strip. He was seemingly damaged, possibly intentionally, and then recovered by Benny. He then allowed a member of the Followers of the Apocalypse to examine the securitron, in exchange for repairing and programming the securitron.

Interactions with the player character
After speaking to Mr. House, the Wild Card series of quests will begin. From this point onwards, the Courier will be able to go up to Benny's penthouse in The Tops Casino. There he will find Yes Man. Yes Man will explain what Benny's plan was; to dispose of Mr. House and plant Yes Man's A.I. in the Lucky 38 mainframe. The player can then choose to continue Benny's plans, and start the Wild Card: Change in Management quest.

Should the player complete that quest, Yes Man will take Mr. House's place in the Lucky 38.

Appearances
appears in Fallout: New Vegas.
