They're noted for their extreme speed and generally docile nature, though like any creature they'll fight back if threatened.

Both names appear in the source material, suggesting they may refer to distinct breeds within the same creature family. The distinction between these two designations isn't clearly explained in available sources, though both names continue to appear in BIONICLEBIONICLE: Matoran AdventuresA 2002 GBA platformer where you play as one of six Matoran fighting Bohrok across Mata Nui's islands. references.

The Name Question#
Rahaga KualusKualusKualus is a Toa of Ice and member of the Toa Hagah, formerly serving as one of the elite bodyguards of Makuta Teridax before dedicating himself to the protection of the Matoran. White and metallic blue in color, he wields a Sub-Zero Spear and a Rhotuka Launching Shield, and wears the Great Mask of Rahi Control, granting him the power to direct the minds of animal life. He resides on Spherus Magna. has noted that the name "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." may be incorrect for the species and could even be an insult in their own language. This suggests that RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts. naming conventions in BIONICLEBIONICLE: Matoran AdventuresA 2002 GBA platformer where you play as one of six Matoran fighting Bohrok across Mata Nui's islands. aren't always straightforward or respectful. The existence of both Goko-KahuKahuKahu were the largest members of the Gukko bird family, ridden by the Le-Matoran Gukko Force across the skies of Mata Nui. and 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. as separate designations adds to the puzzle of understanding these creatures. It remains unclear whether the distinction matters in canon or if it's simply an artifact of inconsistent early documentation.
