Darth Maul and Savage Opress vs Grievous and Phasma

Born on Dathomir to Mother Talzin,[9] Opress was handpicked by the Nightsister Asajj Ventress to become her servant following her grueling tests of Selection, as part of her bid for revenge on her former Master, the Sith Lord Count Dooku. In accordance with their plot against Dooku, Mother Talzin and her Nightsister witches employed their magicks to grant Opress fearsome abilities, placing him under their control. After murdering his beloved brother Feral in a display of loyalty to Ventress, Opress entered the Clone Wars as a Sith apprentice, serving as an enforcer in Dooku's Confederacy of Independent Systems. He executed a mission against the Galactic Republic at Devaron's Temple of Eedit, slaying his first Jedi, Master Halsey and Padawan Knox, in the former campaign. Opress soon became apprenticed to Dooku, who intended to use his new acolyte to overthrow his own Master, Darth Sidious, and claim control of the galaxy.[3] Maul was a Dathomirian Zabrak male who lived during the waning days of the Galactic Republic and the reign of the Galactic Empire. The son of Mother Talzin of the Nightsisters, he was taken as the Sith apprentice of Darth Sidious, the Dark Lord of the Sith, and given the name Darth Maul. After revealing the existence of the Sith to the Jedi Order, Maul supposedly fell in a lightsaber duel against Obi-Wan Kenobi during the Battle of Naboo. Over a decade later, he returned from exile and formed the criminal army known as the Shadow Collective, intent on reclaiming the power he had lost. His quest for revenge against Kenobi and the Sith continued into the Imperial age, bringing him into conflict with the early rebellion against the Empire.
