Nui-Kopen
Giant wasp Rahi that Le-Matoran tamed for travel, but they're far more dangerous when controlled by Toa.

They saw transport. That's unusual.

It's the sort of thing that makes 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. more interesting than simple monsters.
Control and Consequence#
The real story of Nui-Kopen emerges during the enslaving of Le-KoroKoroThe Koros were the six elemental villages established by the Toa Metru on Mata Nui after the Great Rescue, each tied to one element and one Turaga.. One Nui-Kopen held the captured MatoranMatoranThe most abundant species in the Matoran Universe, chosen by Mata Nui to inhabit and maintain his cosmic body. of that village, and it had something 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. desperately needed: his Great Miru mask, replaced with an infected version.

He controlled it. The KanohiKanohiMasks that grant powers and sustain life, they're the most vital artifact in the Matoran Universe. Komau gave him dominion over its mind, turning a 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. meant for peaceful transit into a weapon. That shift from domesticated tool to enslaved creature is telling. Nui-Kopen themselves aren't evil, but they're utterly vulnerable to anyone with the will to dominate them. It's a darker reflection of what domestication really means.
The Mutated Truth#

That's the arc of Nui-Kopen across the canon: from utility to instrument of control, and finally to something that couldn't be controlled at all.
