Worm occupied the deeper sections where the miners rarely worked.

The species' form was that of a large worm. The recorded specimens were sightless and operated entirely by senses other than vision. The species' continued effectiveness as a tunnel predator implied a working combination of vibration sense, chemical detection, and proximity sensing of the kind the larger Onu-WahiOnu-WahiThe underground kingdom of Mata Nui, home to the Onu-Matoran and Toa Onua. burrowers all shared.

The route brought the pair into the deeper passages where the larger 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. of the region operated. The first engagement was with a giant SubterraneanSubterraneanAn Onu-Matoran defector to the Dark Hunters, armed with maces for underground combat. Worm. The creature occupied a section of the route the pair needed to clear, and its sensory profile meant that the ToaThe Toa: Heroes of the Matoran UniverseThe Toa were biomechanical guardians sworn to protect the Matoran, bound by a strict code and defined by sacrifice across every age of the universe. and the TuragaTuragaFormer Toa who fulfilled their destiny and transformed into leaders.

The worm's blindness was not a defensive weakness: the alternative senses by which the species navigated were entirely sufficient to register the pair's approach, and the engagement was active rather than incidental.

The technique exploited the species' sensory profile directly. A blind creature operating by vibration sense in a confined tunnel was vulnerable to acoustic disruption, and the application of focused sound at sufficient intensity could overwhelm the sensory apparatus the worm depended on for tunnel navigation and combat. The exact mechanism, whether OnuaOnuaOnua was the Toa Mata and Toa Nuva of Earth, a quiet, deliberate warrior whose patience and underground mastery anchored his team across the Matoran Universe.'s elemental control of earth was used to amplify a vibration produced by WhenuaWhenuaToa Metru of Earth and later Turaga of Onu-Koro, formerly an Onu-Metru archivist whose career in the Archives shaped his role across the rescue of Metru Nui and the long residency on Mata Nui., or whether the pair used a more conventional acoustic source, was not specified in the surviving record. The outcome was sufficient to clear the worm from the route.

The path beyond the worm did not become easier. The pair next encountered a swarm of Kofo-JagaKofo-JagaVenomous scorpion Rahi that posed a relentless threat to Onu-Wahi's miners and forced the Toa Nuva to use creative tactics during their search for Kanohi Nuva., the small scorpion-form 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. of Onu-WahiOnu-WahiThe underground kingdom of Mata Nui, home to the Onu-Matoran and Toa Onua. that operated in coordinated groups and posed a numbers threat that a single large opponent could not. The swarm was a serious obstacle, but it was not the obstacle that decided the engagement. The route ahead was blocked by a pair of ManasManasManas are a species of Rahi that exist in two color variants, one black, grey, and yellow and the other white, grey, and orange, and are armed with claws., the giant crab-form 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. that served as guardians of the most powerful KanohiKanohiMasks that grant powers and sustain life, they're the most vital artifact in the Matoran Universe. and had been drawn in by the presence of the Kaukau NuvaKaukau NuvaThe underwater breathing mask that could suffocate, but the Toa refused to use it as a weapon. itself.
