Actually Qui-Gon never got into the Jedi councel, as the story goes they have to be in/have been in the councel to disappear when they die. Darth Vader didn't disappear either because he was not on the councel.
To start off this comment I should say I am not any hard-core fan of star wars but I have seen the movies. Anyways my comment is that if I believe right in the other star wars movies the Jedi only disappeared to be able to be in Luke's mind and help him out on his journeys. It is very possible that I am wrong but I believe strongly that I am not.
I know! That is soooooo inconsistent. Obi-Wan disappears and so do Darth Maul and Yoda but Qui-Gon and Darth Vader require cremation! The Jedi God must play favorites. I know he does.
Helloooooo!
Doesn't anyone look at the official Star Wars site anymore?
George Lucas actually tells that we will find out in Star Wars 2 why Qui-Gon didn't disappear.
Oh, and by the way, Darth Vader did disappear. Luke is only burning his suit. (George Lucas tells that, too)
The disappearing act has nothing to do with being on the Jedi Council or whatever the situation. When a Jedi disappears it means he/she has become one with the force. Yoda, Obi-Wan and DarthVader all knew they were about to die and had time to become one with the force, the others didn't!
Nice try, Darth Sense, but Qui-Gon didn't die until after Obi-Wan killed Darth Maul (who then fell into the conveniently placed pit). By that time, he probably knew he was going to die.
I think that a Jedi only disappears if he dies of natural causes, not if he is killed in combat. Obi-Wan is the exception because he willed himself to become one with the force.
That would be true, but technically, Darth Vader was killed in combat from the lightsaber duel with Luke and the electricity from the Emporer.
While we're on the subject, why not just forget it and let George Lucas explain it in the next two episodes!!!!!!!!
I don't think that Darth Vader vanishes because when Luke sets fire to his suit, you can see steam coming out of the mask (sounds a little gross but its true.)
According to Lucas, "That's a plot point that centers around Obi-Wan saying to Vader/Anakin in the first one, "If you strike me down, I will become more powerful than you can possibly imagine." There is an issue about the Force and that will be revealed."
I heard somewhere that the disappearing act was a 'trick' invented by Yoda and taught later to Obi-wan. To back this up, in the novel of ANH, when Obi-wan disappears, Vader becomes wary, unsure of the trick Obi-wan might have played on him.
Some of you said that Darth Vador disappears when he died and Luke is only burning the suit. Well, that's wrong because you can see Luke carrying Darth's body onto the shuttle. He uncovers his head so you know he's still in there.
With the exception of Vader, look at what Obi Wan and Yoda do before disappearing that looks like meditation. It looks like Qui Gon is tying to do this while he's trapped between the laser doors, but got interrupted when they opened and he started to fight Maul again. I don't know about Vader though, my thought is that maybe if the Jedi fade away or are cremated, they become those "ghosts". I heard that Lucas said that Vader disappeared and Luke was just burning his suit, but I didn't hear it myself, so I don't know how true that is. BOOKWORM, if you've ever seen plastic burning, it gives off a strange (toxic) smoke, and since Lucas wouldn't have burned a real person, it's obvious that Vader's plastic costume (lets face it, it may be made of something eles according to the storyline, but in real life it's plastic) is what's produced the smoke you saw.
Jedi's remains have to be burned.
Jedi who died in battle, are actualy killed. Their remains are to be burned.
Jedi who disappear, actualy transform their being to a new entity, seen as 'ghost'.
So they are actualy still alive.
They cease their organic existance, because their bodies became to old to serve them.
After the transformation they become part of the Force and don't serve as jedi anymore. They can only finish the training of their padawans.
Qui-Gon had to be burned because he was killed. We will never see his 'ghost'. He is dead.
Obi-Wan disappeared because he was 'too old for this' - right before Vader stroke him. Quite a smart move. He kept visiting Luke as a 'ghost' or a voice, to finish his training.
Yoda disappeared because his body was dieing. There were no padawans left for him to finish their training. It was only one jedi left - Luke, and before Yoda disappeared he told Luke that his training will be complete after he fights with Vader. Later on we see Yoda as a 'ghost'.
Vader disappeared because he turned to the light side, protecting a jedi - his son. He was not killed by anyone - he left his weak body. Most of his body was mechanical - arms, legs, parts of torso. These remains can not disappear, as the clothes of Obi-Wan and Yoda did not. They had to be burned. Vader became a 'ghost' too, joining the Force as Anakin.
Drath Maul did NOT dissapear. He fell down the well. Hes down there with Timmy (here Lassie...Come Here girl...hee hee) Vader did not dissapear. Only yoda and obi-Wan and actually Qui-Gon did too if you have seen Revenge of the Sith you should know. and if you don't we didn't want you to know...
