Any of the unnamed Jedi in the Star Wars III games. They kick rear... not as much as whatever character your playing at the time. BUT STILL A LOT OF REAR ENDS!
I'd have to say Palpatine, Darth Sidious. He's awsome. The way he manipulates everyone and his skill with the Force is just awsome. I wish that I could train under him. Greatest Sith of all time under Jacen Solo.
