The Diplomat's Ali Ahn Played A Majorly Wicked Supernatural Villain

Before appearing as Eidra Park on Netflix's "The Diplomat," Ali Ahn wrought havoc as an extremely powerful and nearly immortal villain on "Supernatural." She played the role of Dagon, the only female Prince of Hell, during the show's twelfth season, appearing in a total of three episodes.

According to writer Davy Perez, Dagon and the rest of the Princes of Hell were loosely based on Quentin Tarantino's "Reservoir Dogs." "It was what I felt was Supernatural's version of 'Reservoir Dogs' and what would that look like," Perez told Nerdy Girl Express. "Unrelated to that actual structure, I wanted to write an episode about demons and I wanted it not to be about our typical Crossroad Demons. I wanted it to be something very dangerous and deadly."

Dagon is indeed very dangerous, surviving all kinds of worldly weapons since she's a direct creation of Lucifer. Dagon even manages to damage the Colt, one of the only weapons capable of killing her. But Castiel is finally able to take her down, using a combination of angel and Nephilim power, in Season 12, Episode 19.

Though her "Supernatural" days are over, you can keep up with Ali Ahn's latest work by tuning into "The Diplomat." Ahead of the Season 4 premiere on Netflix, Ahn teased that the new episodes will involve a lot of smoke and mirrors around protocol and morality. "The show just keeps getting better," she told Collider. "Now we have Bradley Whitford joining the cast, and people are getting into some shady stuff. People that you don't suspect might be kind of playing with some rules, and it's not clear who the good guy is and who the bad guy is."

That shady stuff likely has to do with the fact that Grace (Allison Janney) and Hal (Rufus Sewell) orchestrated an attack on a British aircraft carrier and acquired a stolen Russian nuclear weapon. Moreover, as indicated by the Season 3 cliffhanger, Kate (Keri Russell) has just discovered the truth of what Hal has done, leaving her with a choice to make. Based on the Season 4 trailer, Kate might end up seeking advice (or even assistance) from Eidra. No matter what happens, though, Ahn is sure to bring the same charm and charisma that she brings to all her roles. "The Diplomat" Season 4 streams on Netflix on October 15.
