Graalok

Graalok was a female Ash Bear who possessed a strong connection with Lewa.

Metru Nui
On Metru Nui, shortly after the Toa Metru arived to save the Matoran, Nokama found a wounded Ash Bear, Graalok. The six Toa were able to heal her.

Graalok later escaped the Visorak web and made her way to Mata Nui.

Mata Nui
On Mata Nui, Takua and Jaller were attacked by her in Le-Wahi after walking into her territory while searching for the Seventh Toa, but they were saved by Lewa.

It is unknown what happened to her after the Toa and Matoran moved back to Metru Nui, though it is assumed she migrated back along with the other Rahi.

Graalok later evacuated the Matoran Universe and traveled to Spherus Magna.
