Sonics Shield



Kohrak-Kal's tool is a sonics shield. It can change its rate of vibration almost instantly, forming a dense sonic barrier that can repel most forms of attack. It is even more impressive when used in attack mode - bursts of sonic emanations can deafen an opponent or, if used at higher intensity, can cause almost any target to stress and shatter.

Set Information
Besides the Kohrak-Kal set, Sonic Shield pieces were also used in the Ussanui set as buttons which started the engine. This was also shown in BIONICLE: Mask of Light.
