Malaketh (Thor: The Dark World) vs. Sidious (RotJ)
For those of you who haven't seen the new Thor movie, the main villian is Malaketh and he aims to use his artifact, the Aether to make the entire universe return to darkness (this is not a spoiler, you are told of his motives within the first five minutes of the movie).
He is powered by the Aether, and he is fully aware of Sidious's powers, and Sidious is aware of his.
Sidious does not get a saber, only the force.
This is a movie version only thread for these two.
Who wins, and why do they win?
