The Fiend fighter of Marrok was a starfighter of the RP82 Fiend variety. The former Inquisitor Marrok piloted this craft while serving within Morgan Elsbeth's forces during that time. Shin Hati, who was his comrade, flew a starfighter that was the same model as the Fiend fighter used by Marrok.
Approximately 9 ABY, Ahsoka Tano, the former Jedi Padawan, along with her Mandalorian apprentice Sabine Wren, journeyed to the Denab system aboard the T-6 1974 shuttle, where the Eye of Sion was situated. Morgan Elsbeth subsequently sent Marrok in his Fiend fighter, along with a squadron, to attack Tano's T-6 shuttle, which led to a dogfight in the vicinity of the planet Seatos.
The initial on-screen appearance of Marrok's Fiend fighter occurred in the third episode, entitled Time to Fly, which debuted on August 29, 2023.
