Which movie actor could fit and cast my character?

My character is a antagonist who comes from his home planet. He is a mischievous king who often kill his people and punishing and executing his slaves. He was the most powerful, most dangerous, most mightiest man in the galaxy. There is dictatorship in his planet and he has a great empire.

His name is Umbrados. He's an alien.

Description: short slick back brown hair, strong and lean, firm jaw, slim face, captivating eyes. A hulking muscular build, selfish, evil, crazy, he loves to be a king and a dictator.

Here's some pictures to look at him.

 

I couldn't get the pics to work. But maybe Christian Bale or Keanu Reeves.

 

It almost sounds like the supposed origins of Scientology, so maybe Tom Cruise? LOL!!!
