Protocairn

"Many centuries ago, a group of Matoran decided to grasp for greater power. They exposed themselves to Energized Protodermis and became reptilian creatures called Protocairns."

- Makuta Teridax, BIONICLE Adventures 10: Time Trap

The Protocairns were arguably one of the most bizarre creatures ever seen on Metru Nui.

History
As the legend has it, the Protocairns were once a group of Matoran from another land who willingly exposed themselves to Energized Protodermis to gain more power. They were mutated into amphibious creatures.

Every hundred years or so after then, Protocairns arrived at various islands and caused enormous destruction, disintegrating large portions of the island's coast. Shortly after, the Protocairns died and their bodies fused together, forming new land in place of the old they destroyed.

At one point, the Protocairns arrived on the shores of Ga-Metru and began terrorizing it. They succeeded in destroying much, including the Great Temple. Eventually, the creatures died and merged into a new landmass. The Great Temple was rebuilt on the Protocairn-created land.

They were extremely difficult to stop, although Vahki began to have success in driving them back a few centuries before the Great Cataclysm.
