'Sleeper Agents'

[clsage]

I'm toying with working up some agents for one of my NPC villains and, while I know I could just design them under a GM fiat saying 'That's just how they are..." the hard core gamer part of me wonders about how to accomplish the following effect:

 

Simply put, these agents would be much akin to (in fact they are inspired by) the 'sleeper' type of Cylons we see in the re-imagined Battlestar Galactica. At the basic level, they would have no memory of serving their controller and might even have their mind fabricate 'false memories' to explain missing time, etc. I would presume that they would, in the main, be somewhat immune to being exposed by a hero mind scanning them because they would fully believe that any 'excuse memories' created are real.

 

So....That is, at its most basic, the effect I want to emulate. Any suggestions on builds?

 

Thanks.
