Toa Hahli is the Toa Inika of Water — one of the six beloved Toa Inika released in 2006 as the heroes of the Voya Nui story arc, and one of the most popular characters in the entire Bionicle line. As a Toa Inika, Hahli's power of Water is intertwined with living lightning — the defining trait of the Inika — and she wields a laser harpoon and Zamor Sphere Launcher as her weapons, wearing the organic Kanohi Elda, the Mask of Detection.
