Krana Yo-Kal were one of the eight Krana-Kal that controlled the Bohrok-Kal. Yo-Kal were created by immersing a Krana Yo into the substance the mutated the Bohrok-Kal. Yo-Kal were the excavator Krana-Kal, with the ability to sense points of stress in the earth and underground movement. Krana Yo-Kal, like the other Krana-Kal, could act independently and could communicate via telepathy. They could also generate a shield around their Bohrok-Kal when about to complete their mission.
