Well, not quite. In fact, the act is called The Deep Space Deviants, and it is led by Paul Dolman, a 47-year-old from Lancashire.
Introducing himself on stage in full costume, he said: "My name is Davros. I am the arch enemy of Doctor Who, and I am here to entertain you!"
"Before we get to that, what’s your real name?" asked Simon Cowell.
"Paul," he answered to laughs from the audience.
"At the moment I’m living in Lancashire, but I’m originally from the planet Skaro," he said. "I think Davros and Simon would get on really well together. He’s evil, he has no conscience, no sense of humour, but he is nice to kids and animals."
Davros... sorry, Paul performed a mashup of Riverdance and The B-52's hit 'Love Shack' with a silent policeman by his side. Unsurprisingly, Simon ended up pushing his red buzzer - but the other three judges loved it.
"It was original, it was entertaining. I mean, I’d expect to see this kind of act on The Voice," said David Walliams. "It reminded me of a young Ant and Dec, at least one of them stood around doing nothing useful. *Cough* Dec!"
"I like the music, and it’s a bit mad, which is everything we’re looking for on this show," Amanda Holden commented. "You've ticked all the boxes!"
"For me, it was just you in a bad mask and half a Dalek," Simon griped.
"Ticks all the boxes!" Paul replied, earning more crowd chuckles.
Paul ended up joining the judges' shortlist with three yesses. If he makes the live shows, maybe he'll bring some Daleks to exterminate Simon?
Britain's Got Talent continues next Saturday at 8.00pm on ITV.
