Lariska

Lariska was a female Dark Hunter. During the Toa/Dark Hunter War on Metru Nui, it was she who gave Nidhiki the oppurtunity to turn his back against his fellow Toa and Lhikan. Nidhiki ended up agreeing, and joined the Dark Hunters. She also was Hakann's first challenger upon his initiation to the Dark Hunters. He managed to bring her down, and was surprised to find her back up and with a knife to his throat the second he turned his back thinking he had beaten her. One of her missions was mentioned in BIONICLE Adventures 10: Time Trap, a job of executing a Toa of Gravity and a Turaga, though the Turaga fled. Lariska had trained with Levitation Kanoka Disks to simulate zero gravity, to prepare for the fight against the Gravity powers of the Toa. She killed the Toa, and received payment for the job, which was given to The Shadowed One. She substituted as head of the Dark Hunters, while The Shadowed One went with Sentrakh to Metru Nui to find out who killed two of his operatives, Nidhiki and Krekka.

Powers and tools
Lariska was known to carry two daggers, which were sometimes prepared with poison on the tips, which she threw at her enemies. Her left arm was completely mechanical due to 'punishment' from "The Shadowed One", but she could still perform astounding acrobatic manuevers. She did not like to rest, preferring to move around and had been known to spontaneously start doing somersaults and backflips. But she could be very quiet when hunting, and had acute senses, which were able to detect Nidhiki, even though he was using a Volitak.
