In Dark Empire there was the Palpatine cloned Emperor.
Another absolute travesty. Did it ever once even occur to them how the notion of Palpatine being "resurrected" via limitless clones (and Luke flirting with the Darkside... again) absolutely takes a huge Cleveland Steamer on the climax of ROTJ, and thus the entire saga?? There are simply not enough words to describe how asinine that idea is. And yet it exists... in the EU.
