Kars is the leader of the Pillar Men, and the designer of the Stone Mask. His goal is to evolve further to become immune to the sun's rays, and thus he seeks the Red Stone of Aja to empower his Masks, battling the Ripple users for its possession. As the creator of the Stone Masks and vampires, Kars is one of the more influential characters in the series, his invention having far reaching repercussions for a number of major characters, such as Dio Brando, the Joestar family and the Zeppeli family. Kars looks down on machines, sneering at the cyborg technology Rudol von Stroheim demonstrates and considering it inferior.[18] Moreover, he considers his vampire grunts to be worthless pawns, unmoved if they are victimized or slain, and willing to execute them himself should they prove annoying to him.
