According to showunner Matt Negrete, they group will face threats the likes of which the main series of The Walking Dead has never seen.

"Oh, boy. I would say episode three has some really great Walkers – or Empties as we call them on our show," he told .

He pointed out that while the undead are referred to as 'Walkers' in the main show, World Beyond's cast call them 'Empties'.

With the show being set 10 years into the apocalypse, Negrete explained that many of the zombies had fused with what they were wearing, or in some cases, each other.

"There's one coming up with a gas mask melted onto its face, which I quite love, and even some Empties that have been fused together to create a monstrous… almost a gorgon with two heads and four arms," he went on.

"We're always looking for ways to mix things up, and we have our usual go-to Empties."

He concluded: "Greg Nicotero and his team always hit that ball out of the park, but the more often we can find some distinct characteristics on these Empties, the better - and we always have fun trying to think outside the box.";

Negrete previously admitted that the special effects team left him vomiting after creating zombies with holes in their faces.

His comments come after The Walking Dead: World Beyond boss promised answers about where Rick Grimes was taken after his mysterious helicopter rescue.

Elsewhere, Maggie Rhee actress Lauren Cohan reacted to the "bittersweet" cancellation of the show.

In the US, the season 10 finale will air on Sunday, October 4 at 9pm on AMC.
