Boggarak

Boggarak were the swarm of blue Visorak with orange eyes and light blue legs, and were the strongest followers of Roodaka. The Boggarak are best at hunting aquatic Rahi, and can "skate" across the surface of water. They are the fastest of the Visorak, and have a great variety of powers. Above water, their Rhotuka spinners dehydrate their target, reducing it to dust. Under water, their spinners cause the target to inflate and float to the surface. The Boggarak also create sonic hums, which they use to transmute solid matter into gas, stone, etc. Due to their loyalty, Roodaka has a personal guard made up of Boggarak. In Bionicle 3: Web of Shadows Roodaka gave proof to Vakama by ordering them to throw themselves out of the ledge when they didn't know there was one, in the book they survived, this proves they are even more loyal to her even if it costs their lives.
