Cere Junda’s Jedi background is nothing to take lightly. She was trained by Eno Cordova (Tony Amendola), takes Trilla Suduri (Elizabeth Grullón) as her student, and, like a few other major Jedi, survives the execution of Order 66. During the early days of the Empire, she avoids being captured or killed by the Imperial Inquisitors. Cere briefly cuts off her connection to the Force but eventually reestablishes it and makes it her goal to restore the Jedi Order. Her burning desire to bring the Jedi back and her Force and lightsaber skills make her a formidable foe for Darth Vader. Still, some aren’t convinced she’s the sole reason the Sith Lord is pushed to his limit.
Over on Reddit, some “Star Wars Jedi: Survivor” players feel Vader is his own worst enemy during the duel. “Vader doesn’t take Cere seriously at the start of the fight. He basically toys with her in the first half of the fight (as seen by him only using one-handed attacks),” commented u/Early-Gap9293, noting that only during the second half does Vader become more aggressive. User u/tombunz added that while Vader is at his peak during the fight, he’s far from the best decision-maker. He may initially underestimate Cere, leading her to gain the upper hand early on.
Regardless of the minutiae of her fight with Darth Vader, the fact remains that Cere Junda was a powerful Jedi who very nearly rid the galaxy of one of its most terrifying and oppressive figures.
