Kars is the leader of the Pillar Men. He is intelligent, ruthless, and single-minded in his dedication to obtaining the Red Stone of Aja. Strangely, despite his apathy towards humans and willingness to kill them, he has been shown to be more compassionate for other living beings. In Switzerland, he sliced a car that was about to hit a puppy in half, and later on maneuvered himself during a long fall to miss a patch of flowers near the bottom of the cliff. Kars' power is that of light; he is able to produce bladed appendages from his arms and use these to reflect blinding light toward his enemies. He also has the same powers over his body that all the Pillar Men share.

He is named after the 80's new wave group The Cars.
