I don't know how people could be so clueless. The emporer appears via hologram in the oot, though the actor was changed for return of the jedi. The fact that it was the same voice and actor who worked in jedi as palpatine. Sidious is obviously his sith name, though the fact that the senator and emporer share the same last name and are played by the same actor? I mean come on people this is laughable.
It is even more laughable that the Sido-dyas subplot was dropped. As he was the dude who ordered the clone army and also happened to be sidious.
Then in the movie it was changed to a dead jedi named syfo. And in the EU it is explained i think that dooku tricked him into ordering the clone army and killed him or something, can't quite remember exactly.
Anyway another EU patch on lucas plot inconsistencies and lack of continuity.
The lack of continuity to the oot is so large a whole you could fly a death star through it as fans have said before.
The sith often have dual personas or personalities. One is false or the person they were.
Palpatine is obviously sidious public face or mask if you will when dealing with the republic or later the empire. Only Vader if anything has any idea who he really is and still does not know his real background.
Vader is obviously Anakin's sith name, though Anakin is the personage and name he abandoned.
It is only now a laughable joke though, and compteley made up of fail. You don't have a good man who fell from grace when there never was any grace to fall from as exhibited by the lousy Lucas prequels.
The forbidden sith practices could have prolonged palpatines life for several centuries if not a thousand years, and do we really know that he was born on naboo. Was he an orphan and taken in and raised to adulthood like Maul?
Was Darth Plagueis real or just another lie of palpatine/sidious?
