Emperor Palpatine vs. Lord Voldemort

I've always thought of Palpatine as a powerful being as far as his control over people and the force goes. He's a mastermind, pretty much. Unfortunately for him, Voldemort would not be one to be controlled.

Almost certainly, Voldemort could absolutely dominate Palpatine with non-spoken spells, and Palpatine would not be able to know it's coming. The arguement that Palpatine could read Voldemort's mind was suggested earlier, but it simply wouldn't happen. It's not even certain that Palpatine CAN read minds, and even if he can, it's very doubtful that he would be good enough at it to get through Voldemort's mental defenses.

As far as Palpatine's other powers go(force powers), compared to what Voldemort can do, they're pretty much just parlor tricks. Most likely Voldemort could simple just shield himself from whatever sort of "magic" Palpatine tries to use.

As badass as Palpatine is, most of his skills would not serve him well in a fight with Voldemort. Voldemort would be victorious.
