On a separate note, i think Palpatine should be grey/evil looking at all times he is cloaked as Sidious leading up to his moment with Mace in ROTS.
One- I dont like the idea of his lightening hurting him, and him being that dumb (Despite being so smart elsewise). So if Luke never threw his lightsaber down, what would Palps have done? Just zapped him anyways and got fried himself like an idiot again. Then, to add more stupidity to it all, he dies by this sammmme thing, in ROS. Like, this is the dumbestttt thing ever, beyond worse than the Death star flaws. I don’t like it and think that should not be what is happening in the scene with Anakin, Mace, and Palpatine.
Two- I think Palpatines natural form is that of an evil skeevy old grand wizard of the sith, and that the image he puts forth to the Senate and Anakin are a lie. That in the moment Mace is zapping him with his own lightening, Palpatine is merely using it as an opportunity to reveal his true form while using it to make it seem that Mace had grievously injured him. All of which were part of Sidious’s grand plan to manipulate the Senate, Jedi, and Anakin into his trap. Like in Primal Fear, Aaron was never real, there was only ever Roy.
