Place in the Gukko family#
Like the other Rahi of the Matoran universe, Kahu were created by the MakutaMakuta (Species)Shadowy Antidermis beings and the Brotherhood's elite, Makuta commanded darkness and shaped the Matoran Universe's fate. to live in that world. The story material links them closely with the GukkoGukkoA large, swift bird-like Rahi domesticated by the Le-Matoran as the mount of the Gukko Force, the second-largest Matoran military unit on Mata Nui., the docile, four-winged birds that the Le-Matoran also tamed as mounts, and with the vulture-like KewaKewaA vulture-like Rahi species native to Le-Wahi, a cousin of the Kahu used as aerial mounts by the Gukko Force of Le-Koro..

The Le-Matoran used "Gukko" for their bird-riding force as a whole, the Gukko Bird ForceGukko ForceLe-Matoran aerial cavalry that defended their treetop home during the Matoran-Rahi War., whichever bird a rider was on. That is why some stories blur the line between Kahu and Gukko. (BIONICLE: Encyclopedia Updated; Mata Nui Online Game)
Behavior and flight#
Kahu were fast fliers whose wings lit up with energy in the air. The Le-Matoran summoned them with flutes and launched riders using signal lightstones, and some birds carried KanokaKanoka DisksThe protodermis disks of Metru Nui, used for sport, self-defence and machinery, carried by the Vahki, and melted down to forge Kanohi masks. launchers strapped to their backs. With one Matoran flying and a second firing the launcher, a Kahu was a proper war mount in the fights against infected Rahi. (Mata Nui Online Game)
The Gukko family as a whole were peaceful birds that fought hard when Nui-Rama threatened their nests. Le-Wahi's riders relied on these birds to cover ground at speed, and in BIONICLE: Mask of Light a Gukko carried TakuaTakuaAn Av-Matoran hidden on Mata Nui as a Ta-Matoran, who gathered the Toa Stones, served as Chronicler, and ultimately accepted the Avohkii to become Takanuva, the Toa of Light. and JallerJallerJaller served as Captain of the Ta-Koro Guard, led the Toa Inika to Voya Nui, and commanded the Toa Mahri through the recovery of the Mask of Life. through the jungle on their search for the seventh Toa.

Kongu's Kahu and Ka#
The best-known Kahu is the bird ridden by KonguKonguKongu captained Le-Koro's Gukko Force before lightning from the red star turned him into a Toa of Air, who later served among the Toa Mahri., captain of the Gukko ForceGukko ForceLe-Matoran aerial cavalry that defended their treetop home during the Matoran-Rahi War.. When the Nui-Rama carried off several Le-Matoran and Taipu, Kongu took TakuaTakuaAn Av-Matoran hidden on Mata Nui as a Ta-Matoran, who gathered the Toa Stones, served as Chronicler, and ultimately accepted the Avohkii to become Takanuva, the Toa of Light. as his second and flew into the hive while Takua fired disks at the swarm. Inside, the infected Toa LewaLewaToa of Air, member of the Toa Mata and Toa Nuva, whose career was marked by repeated possession, body theft, and aerial campaigns from Le-Wahi to Karda Nui. trapped them and injured the bird. It recovered and carried Kongu again when he led the Gukko Force to the Battle of Kini-Nui. (Mata Nui Online Game)
A different book gives Kongu's tamed bird a name: Ka. BIONICLE Chronicles 3 calls Ka a Gukko bird, so it's not clear that Ka and the Kahu from the online game are meant to be the same animal. (BIONICLE Chronicles 3: Makuta's Revenge)

The Kahu set#
The Kahu appeared in LEGO's 2001 range as an alternate model, built from the parts of the Nui-Jaga set rather than sold in a box of its own. (Nui-Jaga)

Frequently asked questions
- What is a Kahu?
- The Kahu is a hawk-like bird Rahi. Many Kahu settled in Le-Wahi on the island of Mata Nui, and their wings light up with energy when they fly.
- What were Kahu used for?
- The Le-Matoran of the Gukko Bird Force rode Kahu as flying mounts in their fights against infected Rahi. A Kahu could carry two riders, one to fly and one to fire a disk launcher strapped to its back.
- Did Kongu ride a Kahu?
- Yes. In the Mata Nui Online Game, Kongu took Takua as his second on his Kahu for a charge into the Nui-Rama hive. The bird was hurt by the infected Toa Lewa but recovered in time to fly at the Battle of Kini-Nui.
- How did Kongu rescue Lewa?
- In BIONICLE Chronicles 3: Makuta's Revenge, the Bohrok-Kal stole Lewa Nuva's power over air and he fell from the Le-Wahi canopy. Kongu, riding his tamed Gukko bird Ka, caught him. The book calls Ka a Gukko, not a Kahu.
- Why did Kualus think "Gukko" might be an insult?
- In Challenge of the Hordika, Rahaga Kualus remarks that "Gukko" might be an insult in the birds' own language, since it isn't what they call themselves. The story never follows the point up.
