It’s so silly. Palpatine ought to have looked in Sith like he did in Clones, and vice versa. That way it would be more believable that he looks the way he does in Jedi.
Indeed. Paply looks older in AOTS than he does in ROTS. I guess the “lightning deformation” is something Lucas improvised when he wrote/shot ROTS, because he obvioulsy had the primary idea that Palpy was just very old in ROTJ.
Maybe that “Benjamin-Buttoning” from AOTC to ROTS is another Sith Power 😉
