Krahka

A Krahka is an intelligent shapeshifting Rahi. One for years made her home in the tunnels beneath the Archives. She has the unique ability to change her form into that of any living being she has seen. In the proccess she gains the powers of those she imitates, can mimic their voices perfectly, and even gains some of their knowledge. A Krahka is capable of speaking and understanding Matoran, forming complex strategies, and decieving virtually anyone. Only the Rahaga have been able to pierce their disguises.

The Toa Metru first encountered this Rahi while investigating a possible flood in the Archives. The Krahka almost succeeded in defeating them, only to fall when she tried to duplicate the powers of all six Toa at once.

After being defeated again by Roodaka, she temporarily joined the Visorak Viceroy, planning all along to betray her. She later began to aid the Toa Hordika. She vanished into the Zone of Darkness along with Tahtorak and a Zivon. The Krahka and Tahtorak returned through a dimensional gate created by Brutaka while he tried to defeat Axonn. She is now back to Metru Nui.

A Krahka has a very distinct personality, considering they are Rahi. they are very defensive of their territory, and will protect it at any cost.
