Kars is the main antagonist from the second arc of JoJo's Bizarre Adventure. He is also the cause of Dio's rise as the main villain of the series making him the indirect antagonist for the whole Jojo series.
Kars is of a race of humanoid beings who lived underground to hide from the sun yet were worshipped by humans as deities or demons. While the rest of his people were contend, Kars wanted to his people to achieve their full potential and created the Stone Mask. But though the mask maximized humans' potentials at the cost of making them vampiric beings, it could not do the same with Kars with only an increased hunger as a side effect. When Kars's people deemed him a threat, he was forced to kill all of them save his only comrade Esidisi and the last two infants of their kind: Wammu and Santana. Years later, Kars realized that mask can achieve it purpose with the empowering properties of the Red Stone of Aja and needs a Super Aja that can fit his mask. Thus Kars left Santana behind while he learns the other to Europe and learned of a Super Aja in the possession of a Roman Emperor. But they were faced by the Hamon Clan, who knew a breathing technique capable of generating energy similar as the sunlight. Kars and the others wiped most of them out before they are forced to enter hibernation under the Roman collesium.
Centuries later, their kind called "Pillar Men" by the Nazis, Kars and his two comrades awaken to find opposition in the Hamon warriors of that time. One of them, Joseph Joestar, would be one whom Kars bears the most animosity towards for killing Esidisi. Following his attempt of taking the Super Aja from Strohiem, revealed to have created a vampire army, Kars decides to accept a challenge from Lisa Lisa in match to determine who can possess the stone once Joseph's match against Wammu ends. But Kars uses a vampire lookalike as a decoy to catch Lisa Lisa off guard in their match and mortally wounds her to get the stone.
Despite being defeated by a furious Joseph, Kars managed to get the Aja-embedded Stone Mask on his face before the Nazis hit him with ultraviolet rays. This allows him to fulfill his ambition to become ultimate life form, able to thrive in sunlight and no weaknesses. Kars then decides to kill Joseph, who leads him to a volcano in hopes that the Pillar Man can be melted by the magma. But Kars survived, chopping off Joseph's arm while developing his own most potent Hamon to kill the human with. But Joseph, acting on a subconscious level, instinctively used the Red Stone to redirect the attack into the ground to cause a massive eruption that sends them into the air. Joseph then distracted Kars long enough to be knocked by the debris into space, where Kars ends up freezing while drifting away from the planet as a frozen immortal.
Kars is cold, rarely showing emotions, but is very sadistic and relentless while bearing deep grudges. He despises humans, but feels compassion for other animals and plants. He even sliced a driver's arms, making it crash just to save a little dog, and bounced around while falling into a large pit so he wouldn't smash some flowers that were at the bottom. He is also very treacherous, resorting to everything to get what he wants.
Aside from all the natural powers of his fellow Pillar Men, like every cell in his body able to produce stomach acid to absorb his non-Hamon imbued victims on physical contact, Kars possesses Light Mode. In that state, Kars creates chainsaw-like blades on his limbs that have very small barbs that run extremely fast. It gives off the illusion of the blades having a glow while making them sharp enough to cut through solid stone.
As the ultimate life form, Kars can access the DNA of all of Earth's lifeforms within his genes to manifest certain traits or spawn animal-like extensions from his body. He also become immune to sunlight and produced Hamon, his only previous weaknesses, and is also able to survive magma by creating a unending shell of air bubbles. He doesn't need to eat or reproduce as well.
