Savage Opress

Savage Opress is a major villain of Star Wars: The Clone Wars. He was Darth Maul's long-lost brother and apprentice born on the planet Dathomir. He is a Dathomiran Zabrak Nightbrother who became a Sith Acolyte along with his brother Maul. Originally a tribal leader on Dathomir, he was picked up by Asajj Ventress and the Nightsisters to assist in Ventress' goal of killing Count Dooku but, Savage had went rogue and instead traveled with his brother Maul all across the galaxy to get revenge on the Jedi and Obi-Wan Kenobi.

Maul and Opress succeeded in taking control of the planet Mandalore, only after seizing it from Pre Vizsla, who had betrayed them after their takeover operation succeeded. Opress was later killed by Darth Sidious, Maul's former master, during a duel at the Sundari Royal Palace.
