Who is the new Doctor Who companion? After so many months of mystery, we suddenly seem to know quite a lot about the future of the franchise, including the identity of the latest companion.

Who is the 15th Doctor’s companion?

Millie Gibson will be the 15th Doctor’s companion named Ruby Sunday, as revealed during the BBC’s annual Children in Need program at the start of 2023.

As filming for Doctor Who series 14 continued throughout 2024, with the two lead actors in their roles, we’ve got to see some first look images of the pair in action. They look brilliant, and we’ve got no doubt they’ll be an awesome duo.

Having said that, Gibson and Gatwa will have a lot of pressure on their shoulders after reports of a new huge budget for the TV series coincided with a deal with streaming service Disney Plus. So, whether the announcement was one that you expected or not, it’s a very, very exciting time to be a fan of Doctor Who and we can’t wait for a cute Lego Doctor Who set with the new duo side by side.
