Pillar Men

The Pillar Men are four powerful humanoids that serve as the main antagonists in Part II: Battle Tendency.

History
The Pillar Men came from an ancient race of humans that had extraordinary strength, intelligence and lifespan. This race once ruled the Earth, living at the top of the food chain and consuming ordinary humans. But the race followed a "rule of evolution": the "higher" it "evolved", the fewer its population became, and it was unable to overcome its adversity to sunlight.

Hoping to overcome their weakness to the sun's rays, Cars invented the stone masks, which can bring out the race's full potential through acupuncture. However, he found that although the mask worked on ordinary humans (and would turn them into vampires), its stimulation was too weak for powerful creatures like the pillar men. However, the race of pillar men, fearing Cars' genius, sought to execute him. Cars massacred the opposing members of his race, including his parents, and subsequently took Wham and ACDC under his wing. Santana's past with regards to these events is not revealed.

Cars sought to combine the stone mask with the Red Stone of Asia to achieve his goal of evolving into an "ultimate life form". To this end, he, Wham, and ACDC traveled to Rome to seek the Red Stone, and defeated the Ripple Clan in a war. However, they were ultimately unable to find the Red Stone of Asia and transformed into stone pillars two thousand years prior to the start of the events of Part II, and went into hibernation.
