Krahka

Krahka is an intelligent shapeshifting Rahi who 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 immitates, can mimic their voices perfectly, and even gains some of there knowledge. Krahka is capable of speaking and understanding Matoran, forming complex stratogies, and decieving virtually anyone. Only the Rahaga have been able to pierce her disguises.

The Toa Metru first encountered this Rahi while investigating a possible flood in the Archives. 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 temporariy joined the Visorak Viceroy, planning all along to betray her. She later began to aid the Toa Hordika. She was last seen vanishing into the Zone of Darkness along with Tahtorak and Zivon.
