Klaus Pachel Bell, also known as Lord Klaus, is the main villain of Xexex.
Little is known about Lord Klaus, other than he rules Planet Pachel Bell and has a desire to rule the entire universe. He invades planet E-Square and kidnaps Princess Elaine, who sends a telepathic distress call to Earth, which sets the events of the game in motion.
Klaus is shown to have a very flamboyant personality, as well as being a cruel sadist, who continually tortures Elaine during her captivity. He has a strange alien pet, which appears with him in some of the game's cutscenes.
