Yes, Darth Maul knew that Darth Vader was once Anakin Skywalker, understanding that Anakin was groomed by Darth Sidious to become the new Sith apprentice, though he didn't foresee the specific cybernetic transformation, and later in Rebels, he focused more on Vader as a threat, recognizing the power of the dark side in him. Maul's visions confirmed Sidious's plan for Anakin, leading him to orchestrate events to try and kill Anakin (and Obi-Wan) before he fully became Vader.
The closest we've seen to both of them confronting each other is during The Phantom Menace, and Maul knows that Anakin became Darth Vader during Order 66, and they were close to seeing each other in the rebels episode “Twilight of the Apprentice”, but it just never happens.
In 0 BBY, a duel was fought on the moon Kalakar Six between the Sith Lords Darth Vader and Darth Maul.
With his last breath, Maul asked Kenobi if he was protecting the Chosen One, to which the Jedi Master said he was, having come to believe that the prophecy would be fulfilled by Luke instead of Anakin. With that, Maul died believing that the victims of the Sith would be avenged.
How does Darth Maul view Darth Vader? Darth Maul held a grudging fear and respect for Vader, recognizing him as a being of unparalleled strength within the Sith hierarchy.
Darth Maul was stronger than Obi Wan, he proved that when he killed Qui-Gon but he was over primed and traded being a showman for his life. Another contender for the weakest Sith could be Count Dooku, or has he's also known Darth Tyranus.
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.
According to this article, Christian Bale was considered to play Anakin Skywalker in the Prequels instead of Hayden Christiansen.
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.
He may have been worried about revenge. An alternate theory would be that he just didn't know. Palpatine kept his true identity very secret. He probably only revealed it to Dooku to better lure him to the dark side.
So, sadly, she no doubt knows Vader is dead, but unless she meets or connects to Luke through the Force she doesn't know that Luke did what nobody thought would happened and brought Anakin back.
Vader breaks free of the operating table and takes a few steps before doing the only thing anybody in his position could do, he screams an unholy, bloodcurdling scream. His vocal computer has nothing close to this sound in its database so it translates it to the infamous 'Noooooooooo'.
The Phantom Menace
In the film's climax, Maul duels Qui-Gon and his apprentice Obi-Wan Kenobi (Ewan McGregor). He is able to kill Qui-Gon and knock Obi-Wan down a shaft, but Kenobi propels himself out of the pit and uses Qui-Gon's lightsaber to bisect Maul, sending the two parts of his body falling down the shaft.
Is Darth Vader dead or alive in Ahsoka? Darth Vader is dead at the time of the events in Ahsoka. What happens in the Disney Plus series comes a few years after Darth Vader's death, which occurs during his clash with Emperor Palpatine in Star Wars: Return of the Jedi.
I genuinely believe ahsoka was one of yoda's favourite Jedi ever!!!
Anakin Skywalker, one of the main characters in the "Star Wars" films, meets the criteria for borderline personality disorder (BPD).
