Obi-Wan Kenobi seemed weak against Darth Vader in A New Hope because he was deliberately holding back, out of practice from years in exile, and emotionally compromised, while Vader was also hampered by his suit and new fighting style; their slow duel was a strategic sacrifice, not a display of true power, as Obi-Wan wanted to let Luke escape, and by the end of the Obi-Wan Kenobi series, he regained his power.
It's how he absolutely demolished Vader toward the end of their fight. The whole point of Kenobi being weak for most of the series was to show a side of him we'd never seen before — an older, retired, near-hopeless man who spends the rest of his days hiding who he truly is and protecting a child.
In canon it was Kirak Infil'a , Cere Junda, Obi-Wan and Lord Momin . All messed him up quite badly with Kirak winning round 1 but losing round 2 and Momin cutting off his arm. Obi-Wan actually beat Vader. In Legends it was Shaa Koon, An'ya Kuro, a clone of Maul and Galen Marek.
For most of the duel, Vader had the upper hand and seemingly defeated Obi-Wan. It was only after Obi-Wan was inspired by his love for Leia and Luke that he was able to defeat Vader. Essentially, Obi-Wan received a Light Side boost while Vader was taken by surprise.
However, it can be seen that as Vader's mastery of the power of the dark side continued to deepen, he gradually suppressed Obi-Wan, and even defeated Obi-Wan Kenobi without using his full strength. It can be said that in the later period, Vader was stronger than Obi-Wan in the use of the Force and lightsaber.
Mace Windu - Vaapad style thrives on dark side energy, and Mace beat Darth Sidious in a duel. He could turn Vader's rage against him. Obi-Wan Kenobi (at peak, Mustafar era) - Already beat Vader at his prime (Anakin) once.
The saddest Star Wars deaths often involve poignant sacrifice, broken relationships, or innocent lives lost, with fan favorites including Kanan Jarrus (heroic sacrifice for his family), Duchess Satine (Obi-Wan's lost love, brutally killed by Maul), Clone Trooper 99 (innocent loyalty and tragic end), Tech (sacrifice for his squad), Padmé Amidala (heartbreak and loss of hope), and Han Solo (fatherly tragedy). These deaths resonate due to their emotional impact, the characters' potential, or the deep impact on other heroes.
No, Darth Plagueis is not Anakin Skywalker's biological father, but there's a strong theory (especially in Star Wars Legends and early drafts) that his experiments with midi-chlorians to create life led the Force itself to create Anakin, the Chosen One, as a reaction, making Plagueis the "unintentional father" of the prophecy. In current canon, Plagueis is a legend Palpatine uses to lure Anakin, and the exact nature of Anakin's conception by the Force remains a mystery, though he had no conventional father.
It kicks off right after the end scene of ROTS and shows Vader beginning his hunt for Jedi in his new body. His very first target is a Jedi Kirak Infil'a, a Jedi who lived for combat who nearly kills Vader.
Kenneth Colley, whose stone-cold portrayal of Admiral Firmus Piett, Darth Vader's trusted officer, in the Star Wars film “The Empire Strikes Back” turned him into a fan favorite and earned him a call back for “Return of the Jedi,” has died.
It is widely speculated that Palpatine deliberately ensured the suit would be agonizing, keeping Vader angry, dependent, and subservient—turning pain into a tool of control.
While Maul did finally let go of his hate for Obi Wan, it was undeniably stronger than Vader's. No matter how much Vader resented Obi Wan for not sticking up for him enough and brutally injuring him on Mustafar...he still deep down still a degree of fondness due to the time they spent together as Jedi.
In a study published in the journal Psychiatry Research, French psychologists and psychiatrists determined that Darth Vader had six of the nine criteria used for a BPD diagnosis, as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM): Impulsivity. Rage and anger management issues.
Revenge of the Sith
Palpatine explains that Plagueis was so powerful and wise, he had mastered the dark side of the Force to such an extent that he could cheat death (mostly saving people he cared about from death) and create life; unnatural abilities which are unknown to the Jedi.
In Star Wars lore, Order 37 was a grim Clone Trooper contingency plan to capture a wanted individual (often a Jedi) by taking a civilian population hostage, locking down the area, and threatening mass execution if the target wasn't surrendered, making it a horrific tactic used by the Empire to force Jedi compliance. It was considered more brutal than Order 66 because it targeted civilians directly, forcing Jedi to often turn themselves in to save innocent lives, as seen on planets like Bellassa.
Even when she first met Darth Vader, Leia was not particularly aware of her connection to the Force. Leia grew up as a princess on Alderaan and later became a senator on Coruscant. Her adoptive father, Bail Organa, did everything in his power to protect Leia's true identity from being discovered.
Obi-Wan has the mental edge over Anakin. There's a strong emotional connection between them and he knows him back to front. He knows how to frustrate Anakin into making mistakes and his defence is so good, it can withstand Anakin's ferocity.
Anakin. Harry's feats are weaker all round, and his ability to fight is too reliant on his wand, whereas anakin can fight without a lightsaber if lost/destroyed, and has means of returning it to his hand if only disarmed.
