Regirock was composed entirely of gray and orange rocks. The seven dots of light on its head formed an "H," as well as Regirock's face.
As one of the three original helpers that Regigigas, the King of Sacred Pillars, had "molded" from various underground rocks to pull shattered continental plates, Regirock was better known to many Trainers than other Legendary Pokémon.
In the Hoenn Region, the tale of Regigigas pulling the continental plates was told to many children as a bedtime story. In the story, Regigigas led the Rock Sacred Pillar—Regirock, the Ice Sacred Pillar—Regice, and the Steel Sacred Pillar—Registeel, piecing the broken fragments of the continent back together along the way. That was how the many regions of vastly different styles came to be, making them Pokémon with the power of creation.
People might no longer remember their names, but the legends they had left behind had been passed down through generations. They were respectfully called the Four Sacred Pillars, meaning the pillars that held up the Pokémon world.
As for the later Electric Sacred Pillar—Regieleki—and Dragon Sacred Pillar—Regidrago, they had appeared much later and had never been included in the "creation legend." According to Ye Lan, they might even still be "unfinished products."
That was why, despite there being six Sacred Pillar Pokémon, only the title of the "Four Sacred Pillars" had continued to circulate.
