Well, first I will go over why he spared them. After Order 66, there were still a number of surviving Jedi. And while Palpatine knew that Vader was perfectly able to kill any remaining Jedi, there were too many for one man to kill alone. So, instead of killing all the Jedi he found, some were captured and tortured.
Qui-Gon is one of the most powerful Jedi in the saga: highly skilled in the Force and mastering abilities that other Jedi couldn't, including the ability to consciously manifest after death. But more than his abilities as an individual, it was his maverick philosophy that the Emperor feared.
Sidious quickly murdered Jedi Masters Agen Kolar, and Saesee Tiin almost immediately, while Kit Fisto was murdered only a few seconds after, but Sidious had an extended confrontation with Windu. The lightsaber duel lasted until Windu disarmed the Sith Lord and knocked him to the floor.
In the final days of the Clone Wars, Windu turned to Kolar again, calling on him, Saesee Tiin and Kit Fisto to arrest Supreme Chancellor Palpatine. Confronted by the Jedi, Palpatine threw off his guise and revealed himself as Darth Sidious. He ignited his crimson-bladed lightsaber and struck down Kolar.
Moreover, throughout the duel, Yoda continually adapts to and even matches Palpatine - forcing his enemy to constantly attempt new tactics. Palpatine clearly hated Master Yoda with a fierce passion, but he was under no illusions that the Grand Master would be easy to defeat.
In an early Revenge of the Sith draft, Palpatine confirmed that Darth Plagueis used the Midi-chlorians to start the cell division that created Anakin Skywalker.
A Sith Lord with the ability to cheat death and create life, Plagueis is the enigmatic mentor of Sheev Palpatine / Darth Sidious, who, in accordance to the Sith's Rule of Two, eventually betrays Plagueis by murdering him in his sleep, taking his place as Sith Master.
In the canon timeline, Mace Windu is known as the Jedi Order's greatest champion. With this in mind, it's easy to understand why Mace is one of the few beings capable of defeating Palpatine.
A grim Jedi Master with an amethyst-bladed lightsaber, Mace Windu was the champion of the Jedi Order, with little tolerance for the failings of the Senate, the arguments of politicians, or the opinions of rebellious Jedi.
Summary. Palpatine's true source of power comes from his intense hatred for everyone in the galaxy, which only fuels his strength. Not only that, but the more people hate Palpatine, the stronger he becomes as well, making inspiring hatred a crucial part of increasing his strength.
In truth, the Sith normally wielded enough powers to fight without a lightsaber, but every apprentice still learned to use one as part of his or her training. Sidious himself felt that he and his peers had outgrown the use of lightsabers, and only continued carrying them to mock the Jedi.
Look, he definitely isn't Mace Windu's son: the age doesn't match, considering the other character's ages (Luke, Leia, Vader, Solo, etc.). However, i think it's possible to see Finn as his grandson, but for that you must consider that Windu had a secret baby close to his time of death.
Yes. This is going to be unpopular, however, it's fairly clear from various sources, including Lucas himself, that Palpatine did let Mace Windu win. Lucas himself noted during hos commentary on the film But this part where he, he pretends to lose his power and be weak was something I added later.
That notwithstanding, Master Windu was also one of the best. If the two spared as Jedi, Dooku would probably win the match because he was the better all-around duelist.
Qui-Gon Jinn learned to manifest as a Force ghost after death, thus allowing him to retain his consciousness in the Force. Several other Jedi also achieved the same ability, most notably Obi-Wan Kenobi, Yoda and the redeemed Anakin Skywalker.
All clones were given a behavioral modification biochip that could be activated by remote order via voice command; Supreme Chancellor Sheev Palpatine, for example, only needed to tell clones to execute Order 66, and the order was carried out.
However, instead of cloning himself at first, Palpatine cloned Plagueis, resulting in Snoke. The novelization tells us the cloning method was imperfect: Rey's dad was the sole survivor, but he was not Force-sensitive.
Born on the planet Hyperkarn in 15 ABY, Rey Palpatine was the daughter of Dathan and Miramir. While their names were lost to history, Rey's father was the cloned son—an artificial genetic strandcast—of the resurrected Darth Sidious, making her the granddaughter of the fallen Galactic Emperor and Dark Lord of the Sith.
