"Zero Hour" Episode Guide | Star Wars Rebels - S3 E21 & 22

The last unaccounted for Grand Admiral of the Imperial Navy, Thrawn is a brilliant strategist as ruthless as he is cunning. When the Empire needed a strong commander to dismantle the rebellion on Lothal, they called upon Thrawn, known for studying his enemies — including their art and culture — to gain tactical advantages often overlooked by his peers. Exiled into parts unknown with the Jedi and rebel Ezra Bridger during the Battle of Lothal, should he return to the galaxy, Thrawn has the potential to plunge the New Republic into war once again.

Elite Imperial soldiers, death troopers are encased in specialized stormtrooper armor with a dark, ominous gleam. These troops serve as bodyguards and enforcers for figureheads including Director Krennic, a highly placed officer within the Advanced Weapons Research division of the Empire, and later Moff Gideon and others.

A remote world of rock, the rebellion sought to establish a secret base on Atollon. But the planet was not as devoid of life as originally believed. Giant, multi-legged, spider-like creatures called krykna lived below the surface. They were aggressive beasts and relentlessly attacked the rebels. Eventually, the freedom fighters were able to repel the krykna using sensor markers and could keep their new home base.

General Jan Dodonna serves as the military leader of the rebel base on Yavin 4. His calm demeanor hides an incisive, strategic mind that serves the Rebellion well.

An ancient being, Bendu lived on Atollon, site of an early rebel base. He was massive in size and blended in with the planet’s coral-like landscape, remaining in a deep slumber until Kanan Jarrus’ imbalance awoke him. He called to the Jedi, recently blinded by Darth Maul, and began to train him in letting go of his fear and regret.

Clan Wren is among the most storied of Mandalorian warrior families. Part of House Vizsla, Clan Wren aligned with the Empire and Gar Saxon under duress. The clan broke ties with the Empire, however, following a reconciliation between leader Ursa Wren and her daughter Sabine. Now, Clan Wren stands with Bo-Katan, leader of Mandalore.
