Klakk

Klakk were bat-like Rahi that were created by Mutran. They could create powerful sonic screams, which could quell a Makuta, destroy the barrier that keeps light from naturally returning to a being, and reverse the effects of a shadow leech, Avsa, or Gorast's stinger, thus changing whoever was affected by any of those things back to normal. The first Matoran to return from being a Shadow Matoran to normal by the Klakk was Vican.
