Hahli

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

Matoran
Hahli was never too active until the Pahrak attack on Ga-Koro. There, she and Macku helped dismantle the causeways so the Pahrak couldn't get over to the Ga-Koro village. She also developed a close friendship (maybe even a romantic one) with a Ta-Matoran named Jaller, Captain of the Guard.

To her surprise, after the Bohrok-Kal had been defeated, Nokama chose her as Kolhii champ instead of Kotu. She went around the island with Macku, training up and meeting several Matoran. Eventually, they got into the Kolhii Championship in Ta-Wahi where Po-Koro and Ta-Koro were playing. Their team beat the other teams, although the Po-Matoran were close. But that was when the Mask of Light slipped out. She wanted to speak to Jaller, but he had to leave quickly as herald. Visit the Mata Nui Online Game 2 for a more detailed writing about her journey as a Kolhii player.

When Jaller died and Takua transformed, she mourned greatly for him. She was the one who proposed putting his mask upon the Ussanui, as a symbol of leading one to victory and a new light. She even snuck into the Ussanui and went down with Takanuva into Mangaia. There, Takanuva sent her back to get the other Turaga and Toa Nuva and tell them to come. After the battle, with Takutanuva lifting the door, she ran by with Jaller's mask. She was stopped by Takutanuva, however, who gave up part of his life force to bring Jaller back to life.

Hahli went to Metru Nui by boat along with all the other Mata Nui Matoran. She was chosen by Jaller to accompany him and some others to Voya Nui.

Toa Inika
Like all other Toa Inika; Toa Hahli Inika has lightning powers with her water powers, and must always be used together (i.e.-She cannot create a flood without the water having lightning in it).

In Bionicle Legends 3: Power Play, Jaller uses his Calix in order to save her from falling into Lava.

Toa Mahri
The Toa Inika will venture down to Mahri Nui and will be transformed into the Toa Mahri. She will wield a Cordak Blaster and Protosteel Talons. {At the Lego Press 2007 they gave a description of Toa Mahri Hahli:

''With her six wing-like fins, Toa Hahli can soar through the water at amazing speeds and strike faster than the eye can see. Armed with a Cordak revolving blaster and steel claws, she’s ready to fight.''
