Ripuri

Ripuri was a Matoran and Dream Keeper in Matoran form. Ripuri was a worker in the Koro and helped out with many errands including helping the Turaga. He originally went by a different name, Kirium, up until the Great Cataclysm. But when he moved to Mata Nui, his memory of his past life was wiped away and no one knew his name, not even him. Matoran called him whatever they liked, up until the Toa arrived.

He was consumed by the Great Spirit of Ripuri, giving him a new name; he was assigned to a new duty. That duty was to help the Toa search for the six Great Kanohi masks of power. During his journey throughout the Island, Ripuri formed a small party called the Traveling Party of the Masks.
