Kars

Cars (sometimes written as Kars or Kaaz) is the major antagonist featured in Part II: Battle Tendency.

Character
Cars is the leader of the Pillar Men. He is intelligent, ruthless, and single-minded in his dedication to obtaining the Red Stone of Asia. Cars' 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. When he gains the power of the red stone, he becomes invulnerable to sunlight, and also gains some abilities on a genetic level - he can produce living creatures and control them, and can mutate his body into various forms. He outlasts his comrades and eventually does gain almost unlimited power as the ultimate "evolved" man through the Red Stone of Asia and a stone mask. In a final confrontation, he succeeds in severing Joseph's hand but is eventually blown into space by a volcanic eruption as well as an ultimate Ripple attack from Joseph. Being immortal, he does not die; however he is unable to return to Earth after being thrown out of orbit. Trapped in the void of space for eternity, he eventually stops thinking and desires death.

Steel Ball Run
In Steel Ball Run, Magenta Magenta dies at the bottom of a river. As he hopes for for Dio's rescue that would never come, he eventually stops thinking. Magenta Magenta's death in Steel Ball Run indicates he is the alternate universe counterpart to Cars.
