I recently finished painting three Crooked Dice Games 28mm scale Doctor Who companions, although for copyright reasons, CDG has renamed them. These were a lot of fun to paint.
In the centre of the group is Miss Freeman, who appeared as Martha Jones (as played by Freema Agyeman) in the Doctor Who series. She is also standing in a casual pose with her arms crossed.
I imagine that most people would buy these figures to use as Doctor Who companions. But they work equally well as normal civilians and civilians are a lot like zombies - you can never have too many of them. Each one costs £4.00 from the CDG webstore.
