At the beginning of "Ahsoka," Morgan Elsbeth's dark Force mercenaries are a trio: Baylan Skoll, Shin Hati, and Marrok (Paul Darnell). Of the three, Marrok is both the most mysterious and the least important, as he gets his ticket punched by Ahsoka herself in Episode 4, "Fallen Jedi." He only gets a couple of lines and two fight scenes for us to pick apart, but there's a lot of interesting stuff within his brief time on the screen.
According to official synopses from Lucasfilm, Marrok is a former Imperial Inquisitor. And in true Inquisitor fashion, he wields a spinning double-bladed red lightsaber in battle. We see him use the Force to throw and pull the weapon back to him during his first duel with Ahsoka on Corellia, and we also see what a skilled pilot he is in Episode 3, "Time to Fly."
All of that information would suggest that Marrok went rogue after the Empire fell, eventually joining up with Baylan, Shin, and Morgan to survive. However, his death on Seatos throws all of this into doubt. When Ahsoka delivers the killing blow to Marrok in his final battle, a cloud of dark green smoke erupts from the wound, followed by a blood-curdling scream. Some have speculated that this could be the result of Nightsister magic, which is often marked by green smoke. Since Morgan Elsbeth is a Nightsister, she could have worked some mojo on Marrok or even brought him back from the dead. Whatever the true explanation, he's a cool-looking character who provided some fun action moments before his demise.
