PETRIFICATION DEVICE

The Petrification Device (石せき化か装そう置ち Sekika Souchi), also known as the Petrification Weapon (石せき化か武ぶ器き Sekika Buki), or the Medusa (石化武器メデューサ Medyūsa), are highly-advanced devices that can induce petrification.

The devices' arrival on Earth directly caused the collapse of society through the petrification of the human species. Thousands of years later, just a few centuries prior to the story's events, a large number of additional devices rained down from the skies above Treasure Island, prompting its inhabitants to abuse their power.

The South America Arc later unveiled that the initial world petrification event involved countless devices, enough to form a colossal pyramid at ground zero. By the end of the series, it was revealed that the devices are sentient, mechanical lifeforms responsible for the Why-man phenomena.
