'Loki' director Kate Herron says it was 'important' to include a reference to Loki's gender fluidity on the show

• "Loki" director Kate Herron spoke to Insider about the titular Marvel character's fluidity.
• A recent teaser for the show included a file with Loki's sex listed as "fluid."
• Herron said it was "important" to make that aspect of the character's identity canon in the MCU.

"Loki" director Kate Herron said that it was "important" to recognize the titular character's gender fluidity on the show and officially make it canon in the Marvel Cinematic Universe.

"I would say that details are marked in but it is something acknowledged," Herron told Insider in an interview on Tuesday. "He's gender fluid in the Norse mythology and the comics and it felt like an important thing to, as you say, make sure it's canon."

Herron's comment came in light of a recent teaser for season one of Marvel's new show "Loki," starring Tom Hiddleston as the titular God of Mischief and set for release on Disney Plus on Wednesday.

The six-episode season picks up immediately after a version of Loki from an alternate timeline in 2012 escaped with the Tesseract (the cube that housed the Space Stone) during the blockbuster film "Avengers: Endgame."

The aforementioned teaser showed a conversation between Loki and Mobius (played by Owen Wilson), an agent of the mysterious Time Variance Authority (TVA) who's studied every aspect of the trickster's life. The clip included a glimpse of Loki's TVA file, which listed his sex as "fluid."

Loki is one of many Marvel characters on the LGBTQ spectrum in the comics. In the source material, the shape-shifter's fluidity was made clear in "Original Sin Vol. 1 No. 2." But the MCU hadn't overtly acknowledged Loki's gender since the character made his film debut a decade ago in "Thor."

Hiddleston himself weighed in on Loki's identity during an interview with Inverse, saying: "Breadth and range of identity contained in the character has been emphasized and is something I was always aware of when I was first cast 10 years ago.

He added: "I know it was important to Kate Herron and [head writer] Michael Waldron and to the whole team. And we were very aware, this is something we felt responsible for."
