Crystal Climber
Knowledge Tower Predator of Ko-Metru
Crystal Climbers were predatory Rahi that nested atop the Knowledge Towers of Ko-Metru, preying on Ice Bats. Hard to dislodge once settled, they were regarded as pests, and some later settled around Mount Ihu on Mata Nui.

One theory held that too many Climbers on a tower could bring it down, so they had learned not to gather in large numbers. They were built for the heights: sharp claws that could grip cold, slippery surfaces, a long, thin tail for balance, and excellent night vision. Their glowing red eyes were a common sight on a Ko-Metru evening. (BIONICLE: Rahi Beasts)
