BBC’s Doctor Who has aired the return of one of the most iconic monsters – Sutekh the Destroyer.

Saturday’s episode, The Legend of Ruby Sunday, confirmed that the villain – who first appeared in the 1975 serial Pyramids of Mars and faced off against Tom Baker’s Fourth Doctor – would return in this year’s finale.

In the new episode, the Doctor (Ncuti Gatwa) tried to identify Ruby’s mother by reconstructing CCTV footage in 3D, but they were unsuccessful, leaving her emotional.

A dark red cloud then appeared inside UNIT’s time window device and then escaped into the corporeal world.

Later, Susan Twist – who has been a recurring guest star and was thought to be the Doctor’s granddaughter –  morphed into a demonic entity while still on a worldwide livestream, leaving the Doctor stunned.

Sutekh described itself as both ‘mother and father’ to all of the gods of chaos in the universe, warning: ‘He has hidden in the howling void.

‘He has hidden within the tempest. He’s braved the storm and the darkness and pain and he whispered to the vessel. All this time, he whispered and delighted and seduced and the vessel did obey.

‘The Lord of Time was blind and vain and knew nothing.’

Fans praised the episode, with one penning on X: ‘Rather enjoyed that Doctor Who episode. Best of the series’;

‘That reveal was 1000/10’; ‘What an amazing episode. I cannot wait until next week!’

It comes after Doctor Who made history on Saturday night as it aired its first ever same-sex kiss.

Fans praised the ‘electrifying chemistry’ between Ncuti Gatwa and Jonathan Groff as they smooched in a groundbreaking move for the show, which started back in 1963.

Episode six of the series took on a historical theme, with the Doctor (Ncuti) and his companion Ruby Sunday ( Millie Gibson ) take a trip to 1813.

While attending a ball in Bath, England the duo cross paths with a handsome bounty hunter named Rogue (Jonathan) as they try and track down the shape-shifting Chuldurs who are murdering the guests.

To begin with, both the Doctor and Rogue accuse one another of being the killer after realising neither are from the Regency Era or Earth.

After convincing the bounty hunter that he is in fact a Time Lord from Gallifrey, the pair work together to find the Chuldur.

As the episode progressed the pair flirted and shocked the guests with same-sex ballroom dancing, initially deciding to create a scandal to unearth the Chuldur.

Their plan saw Rogue get down on one knee and ‘propose’ to the Doctor, after he exclaimed: ‘Tell me what your heart wants, or I shall turn my back on you forever.’

In the final moments, the trio learned they aren’t just searching for one killer but actually a whole family of Chuldurs, but unfortunately both the Doctor and Rogue realise this when its too late for Ruby.

The emotional last scene saw the Doctor in tears as he battled with the idea of sacrificing his best friend Ruby to save the world.

‘Can you lose your friend to save the world,’ Rogue asked the Doctor as Ruby stood alongside the Chuldurs inside a tri-form.

‘Doctor! Press send!’ he shouted.

The Doctor hit back: ‘I can’t. It’ll send Ruby straight to hell!.’

In a twist of events, Rogue sacrificed himself, pushing Ruby out of the way, replacing her with himself in the tri-form, but not before giving the Doctor a kiss first.

‘Find me,’ Rogue whispered before disappearing into the void.

Following the episode fans shared their delight on social media, with one posting to X: ‘Rogue, the subject of the episode’s title, delivers an electrifying chemistry as Jonathan Groff and Ncuti Gatwa bounce off each other with flawless alignment, a fine-tuned, choreographed battle of wits, charm and sexual tension.’

Others agreed: ‘Ok I’m going to need Rogue to return bc I really need to see more of him and the doctor their chemistry is fire and their connection undeniable’; ‘Well, that was just marvellous! So clever! I do hope we see more of Rogue. Great chemistry.’

‘Loved ‘Rogue’ #DoctorWho and please can we see Jonathan Groff again soon?’; ‘I NEED Rogue to be a recurring character in Doctor Who!’; ‘I would love, love, love to see Jonathan Groff here again.’; ‘Getting proper Captain Jack Harkness vibes from Rogue. The Doctor is in love.’

Ncuti is the first queer Doctor Who and the first black Time Lord for a full series.

Others have included married Victorian couple Jenny Flint and Madame Vastra (Catrin Stewart and Neve McIntosh), trans woman Yasmin Finney as Rose Noble and Torchwood’s Jack Harkness played by John Barrowman, who was the first openly non-heterosexual character in the franchise.

In 2005, Captain Jack briefly kissed Christopher Eccleston’s Doctor as he said goodbye to the Time Traveller and his companion Rose, in the final scene of The Parting Of Ways, while believing that he would not survive.

Ncuti told Variety: ‘I feel like anyone that has a problem with someone who’s not a straight white man playing this character, you’re not really, truly a fan of the show. You’ve not been watching!’

He continued: ‘Because the show is about regeneration, and the Doctor is an alien — why would they only choose to be this sort of person?’

Showrunner Russell T Davies echoed the actor’s thoughts: ‘They weren’t exactly the straightest men in the past.

‘You’re talking about someone who does have a lightness and a joy about him that, to me, chimes with queer energy.

‘It’s very rarely driving the story vehemently, but you will see moments exploring it. We’re not delivering a neutered Doctor.’
