Are You A True Star Wars Series Fan?

Explanation
In the Star Wars Expanded Universe (now known as "Legends"), Boba Fett escaped from the Sarlacc pit after his apparent demise in "Return of the Jedi." However, in the official Star Wars canon, which includes the movies and certain TV series like "The Mandalorian," Boba Fett's story continued.
In "The Mandalorian" TV series, Boba Fett survived his encounter with the Sarlacc pit and was shown to be alive. He played a significant role in the series and was portrayed by actor Temuera Morrison. Therefore, as of my last update, Boba Fett was not killed, and his story continued in the official Star Wars canon.

Explanation
Bounty Hunters do not serve only the Empire. They are independent mercenaries who work for various clients, including criminal syndicates, governments, and individuals. While some bounty hunters may choose to align themselves with the Empire, others may work for different factions or operate independently. Therefore, the statement that bounty hunters serve only the Empire is false.

Explanation
In the Star Wars universe, Dagobah is the correct answer because it is the planet where Yoda, a Jedi Master, resides in exile. Luke Skywalker is instructed by Obi-Wan Kenobi's ghost to go to Dagobah to receive further Jedi training from Yoda. This is depicted in the movie "Star Wars: Episode V - The Empire Strikes Back".

Those who have blue light sabers are Obi-Wan Kenobi, Kanan Jarrus, Ezra, and Anakin Skywalker. 

Explanation
Jango Fett died in Episode II. This statement is true. In Star Wars Episode II: Attack of the Clones, Jango Fett, the bounty hunter and father of Boba Fett, is killed during the Battle of Geonosis. He is decapitated by Jedi Master Mace Windu after a fierce fight. This event marks the end of Jango Fett's character arc in the Star Wars franchise.

Explanation
Count Dooku, a Sith Lord in the Star Wars universe, was indeed killed with his own lightsaber. In the movie "Star Wars: Episode III - Revenge of the Sith," during a lightsaber duel with Anakin Skywalker, Dooku's lightsaber is taken from him by Anakin and eventually used to decapitate him under the orders of Chancellor Palpatine. This pivotal moment marks the end of Count Dooku's life and his role in the ongoing conflict between the Jedi and the Sith.

Explanation
These Jedi Masters were killed by Darth Sidious during his duel with Mace Windu in "Star Wars Episode III: Revenge of the Sith."
While Darth Sidious was the orchestrator of the events that led to the deaths of others, some of the other names on your list, such as Yoda, Ki-Adi-Mundi, Plo Koon, Aayla Secura, and Barriss Offee, were not directly killed by him. They died in the course of the Jedi Purge, which was part of Darth Sidious' plan, but they were not killed by his hand. Darth Vader, on the other hand, became an ally of Darth Sidious, so he was not killed by him either.

Explanation
Count Dooku's Master when he was a Jedi was Yoda.
