Morgan Elsbeth is a supporting antagonist in Season 2 of the 2019 Disney+ streaming series The Mandalorian and the main antagonist of Season 1 of the 2023 Disney+ series Ahsoka.
She is a survivor of General Grievous’ massacre of the Nightsisters during the Clone Wars, which radicalized her into a tyrant who provided equipment for the Galactic Empire's naval forces, working directly under Grand Admiral Thrawn.
After the fall of the Empire she forcibly took over the planet Corvus, hoping to locate the exiled Thrawn and bring him back to reunite the Empire. This led her to become the arch-nemesis of Ahsoka Tano, who sought to find and kill Thrawn before he started another war.
