One of my best villians ...... was one of the players.
We were playing a Star Wars campaign and, of course, the players were struggling rebels on a fringe world. Pilots, jedi, wookies, robots and a rebel communications officer named Rel (not the one on the boards BTB). He was always taking the second watch and was a great asset in a fire fight (he had good skills and was increadibly lucky with the dice (no they weren't loaded, I made him use mine one session)).
Anyhoo, what the other characters didn''t know was that he was an Imperial spy who was using the second watch to send location reports and information to the Empire. no matter what the party did, they just couldn't seem to stay ahead of the Empire, finally they "interecepted" a bit of information about a regional governor visiting a remote outpost. They stealthfully inserted into the AO, split into groups for recon and came up with an extraction plan (to kidnap the governor). My wife was playing a brash pilot and she and Rel were to make the strike to get the BBEG. (I had to play the group in separate rooms to keep the information hidden as to what went down with the ther players)
They entered the BBEG's personal chamber and took down the guards that were there, as my wife made her move to bag BBEG, Rel drops her with a stun shot to the back. He kneeled in front of the governor and presented him with his present a rebel spy and new concubine. My wife FREAKED!!! Later the rest of the party found out that a traitor was among their midst and sensing that something had gone wrong charged the quarter's, Rel immediately shot the governor in the back and presented him to the party. Of course my wife is going ape crap at the whole deal yelling "He's a traitor, KILL HIM!!" Rel quiety turns to the party and gives a stirring speech of his secret mission to kill the governor, how he had to get into his confidence and thereby making him an easier target and then outed an NPC trooper as the spy. He even faked a couple of transmissions from HQ to verify it. The rest of the party bought it and killed the NPC, much to my wife's dismay. Later after the campaign was over and we were sitting playing another, we sat around talking about the other games we had played and they commented on the great stroy arc I had created with the spy in the midst of the group and how they were glad they finally got him. I said, "Who said you did?" They all started talking about how they had killed him, "Dan (Rel's player) even showed us the transmissions confirming it." they said.
Dan and I burst into laughter and Dan said, "Uh, guys,
I was the traitor!", he then explained how he did it and my wife, who had been stewing for three months about the whole thing, jumped up and said "I knew it! I knew it! I told you all that he was the
REAL traitor but did you listen to me, no! Next time maybe.... (etc, etc)
And the greatest part was the players would still have believed they got the traitor if we hadn't told them!
