The Voice Command Dalek will conquer Earth or protect it, all depending on your orders. For example, telling it, "Dalek! Seek, Locate!" will put it into a room defense mode, and it will patrol for warm bodies, asking any passerby to identify themselves immediately. Anyone found in a place they shouldn't be gets exterminated (or entertained, depending on how said person reacts to lights and silly noises). There's also a variety of games to be played, from "Identify the Doctor" — where your Dalek servant goes up to whoever is around in an effort to get the Doctor to reveal his identity — and you can even just ask it general questions about the various Dr. Who characters, or have it act in preprogrammed ways.
If you find a situation that requires a more precise touch than the Voice Command Dalek can muster, there's also a remote control for R/C operation, controls for speech included. Want one? Daleks won't be bossed around for cheap: $230.
