Don’t you want to rule over the sun?! To rise above all living things?! To purge your fears and reign forever like gods?!

Kars (Japanese: カルズ Kazu?) is the main antagonist of the second part of the JoJo's Bizarre adventure series, “The Tendency to Battle,” and also the second main antagonist in the series.

Kars is the leader of the Stands People and the creator of the Stone Mask. His main goal is to evolve to the level of a superior being in order to defeat the destructive influence of the sun's rays. To achieve this, he needs the Red Stone of Aisha, which can enhance the effect of the Stone Mask. To obtain the Aisha Stone, Kars is ready to make any sacrifice, including numerous murders of those who possess Hamon.

As the creator of the Stone Mask and vampires in general, Kars is one of the most significant characters in the universe. His inventions had a great influence on other key characters, such as Dio Brando, the Joestar family, and the Zeppeli family.
