Actually, the Dark Jedi clone in Zahn's trilogy is Joruus C'Baoth, not Palpatine (he gets resurrected later, in one of the few works that gives the EU a bad name). The original C'Baoth's earliest chronological appearance is in "Cloak of Deception." Kudos to James Luceno for continuity. Everyone who counts the EU as canon, like myself, must deal with the atrocious "Dark Empire" trilogy, in which Palpatine's spirit takes over a consecutive trio of clone bodies to try and resurrect the Empire. He fails, of course. For anyone interested in Sith/Jedi clones, I recommend "Heir to the Empire" by Timothy Zahn, "Dark Force Rising" by Timothy Zahn, "The Last Command" by--you guessed it--Timothy Zahn, the graphic novels "Dark Empire," "Dark Empire II," and "Empire's End." And, just for the heck of it, throw in "Cloak of Deception." Yes, I am a jerk for advertising the EU and not saying anything pertaining to this thread, aren't I?
