Plo Koon is in The Acolyte because Dave Filoni remains a Star Wars phantom menace

Lucasfilm’s new Star Wars series The Acolyte has earned praise for simply existing outside of the Skywalker Saga — after 47 years of stories set in the same stretch of timeline, a jump back “100 years before the rise of the Empire” to the shinier High Republic era is enough for aching Star Wars fans. But even with a prohibitively old setting and a cast of characters divorced from Anakin and Luke, The Acolyte creator Leslye Headland is still finding ways to pepper the drama with Easter eggs. Episode 4 gave those in the know a whopper: Plo Koon.

Plo Koon, the Kel Dor Jedi known for his chic oxygen mask, first appeared in scenes of the Jedi council in Star Wars: Episode I — The Phantom Menace and grew into a fan favorite when he took on an action role in Star Wars: The Clone Wars. Plo’s biggest fan might be The Clone Wars creator Dave Filoni, who has made his passion for the B-tier Jedi extremely clear to the Star Wars fandom over the last 20 years, having cosplayed at conventions as the Jedi, snapped photos with fellow cosplayers, and showed off his Plo Koon toy collection on social media. His “personal life” section on Wookieepedia is entirely facts about his Plo Koon collectibles. Despite him being one or two levels removed from a Glup Shitto, Dave Filoni is all in on Plo Koon.

I believe Filoni when he says he has talked extensively about Plo Koon with George Lucas. Reportedly, when the animator was pushing to beef up Plo’s part in the The Clone Wars, there were plans to cast an actor who sounded like Toshiro Mifune in Seven Samurai to give the Jedi a samurai feel. But Lucas thought the character was goofier than that and wanted a Jim Carrey type. Filoni landed on actor James Arnold Taylor because of his Gandalf vibes. The Lucas-versus-Filoni Plo-off doesn’t end there; at Star Wars Celebration 2023, Filoni admitted that he made the case to his boss that Plo Koon, due to #skillz, obviously would have survived Order 66. Lucas shot down the canon alteration request,
