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.

Return to Metru Nui
When the Matoran returned to Metru Nui, it was revealed that Mata Nui was not merely sleeping, but dying. Nokama told this to Jaller, and he gathered 5 other Matoran, Hahli being one of them, to go to Voya Nui and save Mata Nui themselves. Takanuva tagged along.

Takanuva had to eventually turn back. When the 6 Matoran went forward, they discovered the Realm of Karzahni, where fire was cold, the ground screamed, and the waterfalls spilled dust. The horrid being Karzahni revealed himself, and made the Matoran switch their masks. Kongu managed to switch his to a Suletu they found earlier.

The Matoran eventually escaped.
