1. Yes Man (New Vegas)
Easily the best character in New Vegas is, of course, Yes Man, the Securitron who becomes pivotal in Benny's plan to take control of the city. Formerly a robot for Mr. House, Benny eventually gained possession of Yes Man and extracted House's personal secrets from it, before reprogramming it as his own robot (though Yes Man is generally compliant to
everyone, as becomes an issue later on). Yes Man becomes an essential component of the plot when uploaded to the Lucky 38 mainframe following Mr. House's murder, helping the Courier take control of the Strip. After the epic Hoover Dam battle, Yes Man finally manages to say no to people, and will only accept orders from the player, which is something of a relief. Still, with his transformative nature and amusing personality, it'd be great to see him show up in some other form in F4, whether it's inside a watch, or suffering from computer senility, or something that cleverly makes reference to the future of the Courier. The Yes Man's return is probably one of the least-likely events to happen, but also the one I'll be most crossing my fingers for.
