Freeza is a sociopathic Arcosian from Dragon Ball Z. He is known across the Universe for his incredible power, and is known for acting quite regal and civilized, yet whilst also being brutal. He commonly uses dark humor and mocks his opponents before killing them. He's fully aware of his brutality and reputation, and revels in it. Cooler is similar to Freeza, but he handles problems in an intellectual and serious manner. Unlike his brother, Freeza, he doesn't underestimate his opponents.
