NEXT time Doctor Who's deadliest enemies bark "exterminate", listen up, they could be speaking with a Valleys accent.
That's the claim of Pembroke's Gareth Hopkins, who says it was his engineer uncle from Merthyr Tydfil and not evil genius Davros who came up with the prototype for the intergalactic tin-pot dictators.
The late Bill Roberts, who also worked on It's A Knockout props, was handed some rough designs to look over by the BBC in the early sixties.
He then refined the appearance of the monstrous creations after being inspired by the hovercraft's methods of floatation - while sitting on a three-legged stool.
"By adding something to cover the head, and a few spokes for arms, the Dalek was born," said his nephew Gareth.
The Daleks return in two weeks' time on BBC One. But this time, they can fly.
"Uncle would have liked that. He was ahead of his time," said Gareth.
