Hahli

Hahli was once a Chronicler, now become a Toa Inika of Water.

City of Legends
Little is known about Hahli on Metru Nui, but she was stuffed into a Matoran Pod and taken away. The Toa Metru later rescued her.

Bohrok Swarm
Hahli helped defend Ga-Koro in the Battle of Ga-Koro. After the battle, she gave Jaller a flower, signalling the beginning of their relationship.

Bohrok-Kal
Hahli gathered with every other Matoran at the Kini-Nui to be rebuilt.

Mask of Light
While Hahli was a humble flax-maker by trade, she was surprisingly elected to the Ga-Matoran kolhii team by Turaga Nokama instead of Kotu. She and Macku traveled Mata-Nui to compete in Kolhii games. In the final game, Ga-Koro won.

When the Mask of Light was revealed, she said goodbye to Jaller as he and Takua set off on their quest. Shortly after Takua became a Toa and Jaller's death, she placed his mask on the ussanui, saying that Jaller would continue to guide Takanuva. She stowed away in the vehicle and survived it's crash.

She gathered the Toa and Turaga, who watched the battle with Makuta. Takutanuva was formed, and lifted the gate to Metru Nui. The Takutanuva told Hahli to stop. He took Jaller's mask, and brung it back to life. Hahli then served as chronicler.

Island of Doom
Hahli understands how vital the mission of the Toa Inika is, but has a hard time adjusting to the constant combat that makes up her new life. The evil and brutality of the Piraka shocks her, even as she wrestles with her own power and how much damage she could do if she ever lost control. She is also puzzled and concerned about her Kanohi mask, which seems to be trying to communicate with her using sudden jolts of pain.

Hahli is a Toa of Water and wields a Laser Harpoon. She wears the Kanohi Elda, the Mask of Detection, which lets her see hidden things including Toa Matoro's spirit form, the mask also gives her headaches as she gets closer to the Ignika Mask of Life.
