The arrival of the villainous telepath has been teased over the past few seasons, with visions teeing up a showdown between him and Lou Llobell's Gaal Dornick. Now, the time has come.
While he did appear briefly in season 2, he's since undergone a recast since we last saw him. Here's everything you need to know.
Who plays The Mule in Foundation season 3 after recast?
Speaking about taking over the role, Asbæk told RadioTimes.com: "It's always difficult to be in the footsteps of an incredible actor as Mikael. But us Scandinavians, we stick together and we collaborate.
As for what we can expect from his incarnation of The Mule? Asbæk rejects the notion that he's a villain, instead telling us that he's "a bit misunderstood."
Asbæk is best known for his role as Euron Greyjoy in Game of Thrones, appearing from season 6 onwards, but he's also appeared in Danish TV series including The Killing and Borgen.
He appeared in Aquaman and the Lost Kingdom, as well as the film adaptation of Stephen King's Salem's Lot.
Who is The Mule in Foundation season 3?
We've already seen him appear in season 2, with Gaal seeing him kill her daughter Salvor (Leah Harvey) in a vision.
However, as the final episode of the season revealed, this vision wouldn't come true as Salvor was killed 150 years earlier than the vision depicted, at the hands of a mentalic still under the spell of Tellem (Rachel House) rather than The Mule.
"His approach to it was so different to mine because he's chasing and Gaal's running," she explained.
"And that's a scary thought because, after him, the math stops working. What is everything that Gaal has lived through been for, if it just ends after that?"
Why was The Mule recast in Foundation season 3?
It's possible that Persbrandt was not available for further seasons, or that his appearance was only ever intended to be brief for season 2.
