10 Doctor Who Fan Theories Better Than What We Got

10. The Lupari Are From Barcelona

Let's start with a silly one.

The Lupari were introduced in Flux as the dog-faced protectors of the human race. No, literally, they had the faces of dogs. That wasn't an insult.

While it's revealed that the Lupari have sworn to protect humanity, their exact origins are never revealed. Enter this incredible fan theory that references the final episode of the very first series of NuWho.

As the Ninth Doctor is about to regenerate, he asks Rose if she wants to visit Barcelona. Not the city of Barcelona, but the planet of Barcelona. He remarks that the world is home to "dogs with no noses", before laughing about how many times they must hear that joke.

The presence of alien dogs clearly got one Reddit user thinking, who suggested that those noseless hounds were early ancestors of the Lupari. Barcelona (the football team) was even mentioned in The Halloween Apocalypse, the episode which introduced Karvanista, a member of the Lupari race.

This revelation wouldn't have changed anything major, but it would've been a nice nod back to the early days of Doctor Who's revival.
