Fresh from the ongoing San Diego Comic-Con, Legion has confirmed a major addition for its second season.

Courtesy of the FX show’s panel, it was announced that Lost and Wonder Woman’s Said Taghmaoui has joined the series as the nefarious Shadow King – a character already alluded to and outright seen at several points in the show’s debut season.

On this news, the network quickly went on to describe the Shadow King as a “villain with a thousand faces. In his real form, he is always nattily dressed. Dapper with a thin Clark Gable style moustache. His eyes forever hidden behind a pair of ornate sunglasses. He was hip long before there was such an idea. He can seductively hold court on any topic and in any language, but his true passion lies in the singular timeless notion of power and amassing as much of it as possible… It is rumoured he is the spawn of the first nightmare, which is fitting because fear is his weapon of choice in exposing weakness in others. To Farouk, fear equals weakness and he fears nothing. Which is why he takes such delight in seeing others squirm – a reminder he is more powerful than them.”

In the comic book world, Amahl Farouk, aka the Shadow King, was created by Chris Claremont, debuting in 1979’s Uncanny X-Men #117. There, he is often depicted as an eerie, sinister, telepathic immortal presence who has caused all kinds of problems for Professor X and his X-Men over the decades.

For Legion’s second season, no other major details are known just yet bar the fact that the episode count will be upped from eight to ten.

As ever, expect more on Legion as its second year continues to develop.
