Darth Vader never kills the Secret Apprentice during the game. He only pretends to so Emperor Palpatine will think the Apprentice is dead which allows Darth Vader to continue with his plot to overthrow the Apprentice.
In the real ending of the game, Emperor Palpatine is the one to kill the Apprentice, however. Well, the Emperor didn't actually kill Vader's Secret Apprentice. They only way I know this is because there is a second game of Star Wars TFU.
No, he does not. Darth Vader's first apprentice (Galen Marek/Starkiller) is killed by Emperor Palpatine/Darth Sidious.
Darth Vader he wanted to distract the emperor so he and his apprentice could kill him But Vader just told his apprentice that it was actually a plot made by Darth Vader to root out enemies of the Empire.
because he is a secret.
no, he does not exist
Darth Vader
Well, You enter a room after versing Darth Vader for time. It depends on who you want to fight Darth Vader or the emperor
It would be Darth Vader's apprentice. Ahsoka Tano (http://starwars.wikia.com/wiki/Ahsoka_Tano) is only a padawan approximately 14 years old. Whereas, Darth Vader's apprentice (http://starwars.wikia.com/wiki/Galen_Marek) was probably about 25 years old. They are both apprentices...but it would be like asking a 14 year old girl to tackle an NFL running back. It's just not gonna happen. He would kill her.
no, they will kill him >.>
Darth Vader would win but just barely it would be an insane battle, but the force would tip the scales to Vader's favor.
Darth Vader's old master was Obi Wan.
Yes ,harry can kill darth vader as harry is good and good always wins and harry can do many curses hexes,jinxes, charms and other spells
Unless the Author brings along some alien artifacts, Darth Vader will kill him easily with the force.
