Exterminate! the Daleks sent small children cowering behind the sofa when they first appeared on TV in the 1960s in their bid to rule the Universe. At approximately 8in (20cm) high, however, this particular example of spin-off merchandising from the BBC series Dr Who is more likely to invoke fond nostalgia than fear.
