Not much has been revealed about the mysterious character so far.
So far, Doctor Who season 14 has seen Ncuti Gatwa and Millie Gibson joined by a whole host of great guest stars – from Jinkx Monsoon to Callie Cooke – but arguably the most exciting addition to the cast for the ongoing run is Tony-nominated actor Jonathan Groff.
The Glee, Mindhunter and Hamilton star will finally make his much-anticipated appearance in next week's Regency-set episode, Rogue, and the BBC has now unveiled some intriguing first-look images of his character.
In one of the stills, he is seen standing alone at what looks to be some kind of dance as several onlookers watch on.
Meanwhile, two additional snaps see him interacting with the Doctor (Gatwa) – who can be seen smiling widely.
We'll have to wait until the episode's debut on BBC iPlayer next Saturday to find out quite what is going on, but fans are certainly desperate to find out more about Groff's mysterious character.
We do already know that he is playing the titular Rogue, while it's now been confirmed by the BBC that he is a bounty hunter who will have a major impact on the Doctor's life.
But beyond that, it's all been kept tightly under wraps – so it remains to be seen exactly how he will slot into the episode and what kind of relationship he'll have with the Doctor and Ruby Sunday.
When quizzed by RadioTimes.com about the Doctor's dynamic with the character at the premiere of the new season, Gatwa said that there was a "chill vibe" between the pair - but Millie Gibson appeared to hint that this might not tell the full story.

The synopsis for the episode provided by the BBC reads: "The Doctor and Ruby land in 1813, where guests at a duchess’s party are being murdered and a mysterious bounty hunter called Rogue is about to change the Doctor’s life forever."
We can't wait!
