Consider this your quick dossier on the saga’s most formidable names and the hard facts that made them infamous.

Darth Vader

Once Jedi Knight Anakin Skywalker, Darth Vader becomes the Emperor’s enforcer after the fall of the Jedi Order in ‘Revenge of the Sith’. He leads the Purge alongside Inquisitors, hunts survivors in ‘Obi-Wan Kenobi’, and commands the Executor-class Super Star Destroyer seen from ‘The Empire Strikes Back’ onward. His life-support armor integrates a respirator and cybernetic limbs, enabling survival after catastrophic injuries on Mustafar. Vader’s track record includes frontline combat, high-level command decisions, and direct engagements with Rebel forces in ‘A New Hope’ and ‘Rogue One: A Star Wars Story’.

Emperor Palpatine (Darth Sidious)

Sheev Palpatine engineers the Clone Wars to seize emergency powers in ‘Attack of the Clones’ and dissolves the Republic in ‘Revenge of the Sith’. Operating as Darth Sidious, he mentors Sith apprentices including Darth Maul and Darth Vader and directs the Imperial Inquisitorius. His political control extends to the Tarkin Doctrine, reflected in the deployment of the Death Star in ‘A New Hope’. Palpatine’s experiments with cloning and Sith cult networks resurface in ‘The Rise of Skywalker’, linking him to the First Order and Exegol operations.

Darth Maul

Introduced in ‘The Phantom Menace’, Darth Maul serves as Sidious’s assassin and duelist, wielding a double-bladed lightsaber. After surviving his Naboo defeat, he returns in ‘The Clone Wars’ and creates the Shadow Collective by uniting crime syndicates like Black Sun and the Pyke Syndicate. Maul conquers Mandalore, duels key Jedi, and clashes with former master-aligned forces. His long pursuit of Obi-Wan Kenobi extends into ‘Star Wars Rebels’, where their final confrontation closes his arc.

General Grievous

A Kaleesh warlord turned cyborg, General Grievous commands the Separatist Droid Army in ‘Revenge of the Sith’ and ‘The Clone Wars’. He is known for lightsaber collection from fallen Jedi and for quad-limb combat enabled by extensive cybernetics. Grievous leads major campaigns across the Outer Rim Sieges and acts under Count Dooku’s strategic direction. His flagship Malevolence and later the Invisible Hand anchor several large-scale engagements with the Republic.

The Grand Inquisitor

Formerly a Jedi Temple Guard, the Grand Inquisitor leads the Imperial Inquisitorius in ‘Star Wars Rebels’. He directs specialized Force-sensitive hunters to track surviving Jedi and Force-adept children, coordinating with Imperial Security Bureau assets. His investigations include Temple archives knowledge exploited to anticipate targets’ methods and hideouts. The Inquisitor’s operations establish procedures later used by other Inquisitors seen in ‘Obi-Wan Kenobi’.

Asajj Ventress

Asajj Ventress appears in ‘The Clone Wars’ as Count Dooku’s assassin and a Nightsister of Dathomir. Trained in dual-saber combat and stealth tactics, she participates in raids, political kidnappings, and Jedi confrontations throughout the war. After Dooku’s betrayal, she allies with bounty hunters and engages in missions across the underworld. Her storyline intersects with the Nightsisters’ arc, including Mother Talzin’s interventions and clashes with General Grievous.

Kylo Ren (Ben Solo)

Kylo Ren leads the Knights of Ren and serves as Supreme Leader Snoke’s apprentice in ‘The Force Awakens’ and ‘The Last Jedi’. He commands First Order operations, including the assault on the village of Tuanul and engagements against the Resistance. His Force abilities include telekinesis, interrogation through mind probes, and cross-guard lightsaber combat. Kylo’s command role expands in ‘The Rise of Skywalker’, where he coordinates searches tied to Sith wayfinders and Exegol.

Supreme Leader Snoke

Snoke appears as the First Order’s political and military head in ‘The Force Awakens’ and ‘The Last Jedi’. He oversees Starkiller Base deployment and strategic strikes against New Republic and Resistance forces. His mentorship of Kylo Ren focuses on battlefield lethality and internal consolidation. Later revelations in ‘The Rise of Skywalker’ connect Snoke to Exegol’s cloning programs and Palpatine’s broader contingency plans.

Grand Admiral Thrawn

Introduced to canon in ‘Star Wars Rebels’ and continued in ‘Ahsoka’, Grand Admiral Thrawn is a Chiss strategist noted for cultural analysis of adversaries. He commands the Seventh Fleet, employs interdictor technology, and enforces strict, efficiency-driven campaigns against Rebel cells. Thrawn’s tactics include targeted strikes on supply lines and manipulation of local politics on worlds like Lothal. His relocation via purrgil hyperspace events sets up later Imperial-remnant movements.

Cad Bane

Cad Bane debuts in ‘The Clone Wars’ as a Duros bounty hunter specializing in high-risk extractions, heists, and hostage operations. He works for various employers, including Hutts and Sith-aligned clients, and uses gear like rocket boots and breathing tubes to counter Jedi techniques. His contracts include raids on the Jedi Temple and kidnappings tied to Senate leverage. Bane resurfaces in ‘The Bad Batch’ and ‘The Book of Boba Fett’, continuing elite-tier contract work.

Moff Gideon

Moff Gideon leads Imperial-remnant forces in ‘The Mandalorian’, wielding the Darksaber to assert authority over Mandalorian factions. He directs research into cloning and Force-sensitivity using facilities like Mount Tantiss-adjacent programs hinted across related storytelling. Gideon’s assets include Dark Trooper deployments, light cruiser command, and covert agents. His campaigns target Grogu for experimentation and test advanced armor and trooper iterations.

Mother Talzin

Mother Talzin heads the Nightsisters of Dathomir in ‘The Clone Wars’, using magick distinct from conventional Force techniques. She orchestrates political and battlefield interventions, including aiding Asajj Ventress and manipulating events around Savage Opress. Talzin conducts rituals for enhancement, deception, and remote influence over battlefields. Her confrontations involve both Separatist and Republic forces, with repercussions across Dathomiri clans.

Savage Opress

Savage Opress, empowered by Nightsister rituals in ‘The Clone Wars’, becomes a powerful enforcer aligned first with Dooku and later with his brother Darth Maul. He participates in campaigns against Jedi targets and helps form the Shadow Collective’s military muscle. Savage’s engagements span multiple theaters, from direct duels to system-level intimidation operations. His arc concludes amid escalating clashes with Republic and Sith adversaries.

The Zillo Beast

The Zillo Beast appears in ‘The Clone Wars’ as a near-indestructible, ancient creature discovered during a Republic-Separatist battle. Its armor-like hide resists high-energy weapons, prompting Republic scientists to study it on Coruscant. The containment effort fails, causing large-scale urban damage and emergency-level responses. The incident raises policy debates on weaponizing biological advantages and the ethics of cloning research.

Darth Nihilus

Featured in ‘Star Wars: Knights of the Old Republic II – The Sith Lords’, Darth Nihilus exists in the Legends continuity as a Sith Lord bound to a mask and armor. He consumes life through the Force, devastating entire worlds by draining their energy. Nihilus commands the Ravager and leads remnants of the Sith Triumvirate during the Old Republic era. His encounters with the Jedi Exile define late-war conflicts outside current canon.
