Obi-Wan Kenobi wins against Darth Vader in their most significant encounters, particularly in the series finale, by using superior strategy, exploiting Vader's internal conflict and rage, and leveraging his own rediscovered connection to the Force, though Vader's raw power is immense; ultimately, Obi-Wan consistently defeats Vader by outsmarting him and refusing to kill him, securing a spiritual victory.
In the end, Obi-Wan prevailed not by overpowering Vader, but by using his opponent's unchecked fury against him. With a final, anguished strike, he left Anakin broken on the lava banks—physically defeated, but spiritually unreachable.
So to summarize: no, Obi-Wan is not stronger than Darth Vader. Despite being back at full power, he still needed a light side boost just to beat a Vader that was weakened by his conflict and his feelings for his old master, and not at the height of his powers yet.
How did Obi-Wan defeated Anakin/Vader twice while so many other Jedi failed? Not to downplay Obi-Wan, as he was a very powerful and skilled Jedi, but Anakin was always considered the most skilled fighter of the order and as Vader he was just unstoppable. But Obi-Wan managed to do it..as Anakin and Vader. Twice!
Obi-Wan Kenobi (at peak, Mustafar era) - Already beat Vader at his prime (Anakin) once. Post-suit Vader is even slower and less versatile. Luke Skywalker (post-ROTJ Legends or Canon TLJ era) - Becomes one of the most powerful Jedi in history. By TLJ, he's surpassed Vader by a wide margin.
The Lost Twenty, also known as the The Lost, was a name given to the group of twenty Jedi Masters who left the Jedi Order throughout its history. According to Yula Braylon of the Jedi High Council, the Lost Twenty became disillusioned with the Jedi way of life.
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.
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.
Why did Obi-Wan's body disappear after his death? Obi-Wan mastered the art of becoming one with the Force, causing his body to disappear and become a Force ghost to guide Luke Skywalker.
That's the most dangerous. Out of those 4 Sidious was the most powerful. He was strong in the force but his ability to manipulate a entire galaxy into crowning him, a Sith Lord, as Emperor and giving him absolute rule over a entire galaxy. He was the only one to achieve the main goal of the Sith, Galactic Dominance.
During Mandalore's Civil War and his apprenticeship under Qui-Gon Jinn, Obi-Wan fell in love with the young Duchess Satine Kryze.
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.
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.
No, Darth Plagueis is not Anakin Skywalker's father; Anakin had no biological father, being born of the Force itself in response to Plagueis's dark side manipulations, with Palpatine's tales of Plagueis's power over life being a manipulation to turn Anakin to the dark side, though Plagueis's attempts to create life did inadvertently cause Anakin's conception.
