Kahu are hawk-like Rahi.
When the Great Cataclysm brought about the creation of the island of Mata Nui, many Kahu migrated there and established themselves in Le-Wahi. The Le-Matoran Gukko Force utilized Kahu as flying steeds in their fights against infected Rahi of Le-Wahi. Some Kahu had Disk Launchers mounted on their backs for combat purposes. Le-Matoran could summon the bird using Flutes. Kahu were launched by a Matoran with signal Lightstones.
A Kahu bird was tamed by Kongu on Mata Nui. He mounted a disk launcher on the bird, and rode it several times in the Great War. When the Nui-Rama swarm attacked, Kongu asked Takua to be his second on the Kahu. The Kahu was later injured by an infected Lewa. The Kahu soon recovered and assisted Kongu in the Battle for Kini-Nui.
Abilities and Traits
A Kahu's wings light up with energy during flight. Kahu are strong enough to carry two Matoran riders, allowing for one Matoran to pilot the bird and a second Matoran to fire a disk launcher.
The Kahu model can be built out of the two Nui-Jaga in the 8548 Nui-Jaga set released in 2001. The instructions for this combination could be found in the purple Nui-Jaga instruction booklets. Its lower body featured a trigger that allowed the Kahu's mouth to open and close.
- The Kahu was, for a long time, not considered to be a part of the official BIONICLE canon, having been completely replaced by the Gukko bird because of a conflict with The LEGO Group using Māori words ("kāhu" being the Māori word for "hawk"). It has since been reapproved by Greg Farshtey not only as a canon Rahi, but also a subspecies of the regular Gukko, along with the Kewa.
- In Matoran, the word "kahu" also means "hawk."
