The novelization of The Rise of Skywalker tells us that the new Sith Lord is a clone of Emperor Palpatine. Not the original, but a clone.
“All the vials were empty of liquid save one, which was nearly depleted. Kylo peered closer. He’d seen this apparatus before, too, when he’d studied the Clone Wars as a boy. The liquid flowing into the living nightmare before him was fighting a losing battle to sustain the Emperor’s putrid flesh.
“What could you give me?” Kylo asked. Emperor Palpatine lived, after a fashion, and Kylo could feel in his very bones that this clone body sheltered the Emperor’s actual spirit. It was an imperfect vessel, though, unable to contain his immense power. It couldn’t last much longer.”
But his face looks scarred like the original.
Why would his face be scarred like the original? If he got a whole new clone body, wouldn't it be new? Did the cloning process somehow mimic the facial scars that he received in his duel with Mace Windu?
