Kahu are hawk-like Rahi.


The Kahu species, a sub-species of the Gukko,[OGDi] was created by the Makuta using Viruses and Liquid Protodermis to be one of the Rahi to inhabit the Matoran Universe.[1]

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.[MNOG, Ch. 6]

Kopaka riding a Kahu

1,000 years later, the Kahu migrated back to the Matoran Universe when the Bohrok swarms were awakened to cleanse the island.[OGDi]

After the Great Spirit Robot was critically damaged in the Battle of Bara Magna, many Kahu emigrated from the Matoran Universe to Spherus Magna.[citation needed]

Kongu's Kahu

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.[MNOG, Ch. 6] The Kahu soon recovered and assisted Kongu in the Battle for Kini-Nui.[MNOG, Ch. 9]

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.[MNOG, Ch. 6]

Set Information

A Kahu in set form

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 of The LEGO Group using Maori terms (Kahu being a Maori term).[OGD] It has since been reapproved by Greg Farshtey as a canon creature but a subspecies of the regular Gukko, along with the Kewa.[OGDi]
  • In Matoran, the word "kahu" means "hawk."[OGDi]
