The Aero Slicers were unique in the team for combining a cutting function with a flight function tied directly to airflow.
Flight function#
The clearest record of the slicers' flight capability is preserved in BIONICLETakua's Quest for the Toa StonesAn alternate-continuity record of Takua the Chronicler crossing Mata Nui to recover the six Toa Stones before the arrival of the Toa Mata. Adventures 4: Legends of Metru NuiMetru NuiThe city beneath Mata Nui functions as the Great Spirit's brain, housing the Matoran whose labor keeps the god alive.. During a chute reversal initiated by KonguKonguKongu commanded Le-Koro's Gukko Force before a strike from the Kanohi Ignika transformed him into a Toa of Air who later served among the Toa Mahri. under Dark Hunter pressure, the Toa MetruMetruIn the Matoran language a metru was a single district of Metru Nui; the city was divided into six such districts, one for each element, and the term covered both the place and the elemental community that lived in it. were caught in the redirected flow. The account records that MatauMatauA former Le-Metru test driver who became a Toa Metru, Matau wielded air, illusion, and shape-shifting before sacrificing his Toa power to wake the sleeping Matoran., with his arms free, drew one of his Aero Slicers and cut a hole in the bottom of the chute, allowing the three Toa MetruMetruIn the Matoran language a metru was a single district of Metru Nui; the city was divided into six such districts, one for each element, and the term covered both the place and the elemental community that lived in it. to dive through before being crushed by an out-of-control freight container.
The flight use followed shortly afterward. The account records that as VakamaVakamaA Ta-Metru maskmaker transformed into the Toa Metru of Fire, leader of his team through the Visorak war, and Turaga of Ta-Koro for a thousand years. lost his grip and MatauMatauA former Le-Metru test driver who became a Toa Metru, Matau wielded air, illusion, and shape-shifting before sacrificing his Toa power to wake the sleeping Matoran. fell, the Aero Slicers caught the wind and turned his fall into a slightly controlled glide before he struck a telescreen. The phrasing is significant: the slicers did not grant proper sustained flight on first use. They provided enough lift to survive the fall, though not enough to avoid the impact entirely.
The same event is recorded in BIONICLETakua's Quest for the Toa StonesAn alternate-continuity record of Takua the Chronicler crossing Mata Nui to recover the six Toa Stones before the arrival of the Toa Mata. 2: Legends of Metru NuiMetru NuiThe city beneath Mata Nui functions as the Great Spirit's brain, housing the Matoran whose labor keeps the god alive., with MatauMatauA former Le-Metru test driver who became a Toa Metru, Matau wielded air, illusion, and shape-shifting before sacrificing his Toa power to wake the sleeping Matoran. accidentally discovering he could fly using his Aero Slicers during the pursuit. Both accounts agree that the flight function was discovered through circumstance rather than trained for in advance.
Combat and channelling functions#

They served as melee weapons in close combat and as conduits for MatauMatauA former Le-Metru test driver who became a Toa Metru, Matau wielded air, illusion, and shape-shifting before sacrificing his Toa power to wake the sleeping Matoran.'s elemental power over Air.

The BS01 entry on the Aero Slicers confirms both the melee role and their use as a focusing point for elemental Air power.

Frequently asked questions
- What were the Aero Slicers?
- The Aero Slicers were the Toa Tools of Matau, the Toa Metru of Air. They functioned as melee blades, as conduits for Matau's elemental control over Air, and, when worn on the back, as gliding surfaces that caught wind and converted a fall into a controlled descent.
- How did Matau get the Aero Slicers?
- Matau received the Aero Slicers at the moment of his transformation into a Toa Metru. The Matoran sealed within Toa Stones, among them Matau, then a Le-Matoran test pilot of Le-Metru, were transformed at the Great Temple, and the Aero Slicers manifested with his new body.
- Could the Aero Slicers actually fly?
- When worn on the back, the Aero Slicers caught the wind and provided limited gliding flight rather than proper sustained flight. On their first use they gave Matau enough lift to survive a fall but not enough to avoid striking a telescreen, and the function was discovered through circumstance rather than trained for in advance.
- What happened to the Aero Slicers when Matau became a Toa Hordika?
- When Roodaka's Visorak venom mutated the Toa Metru into Toa Hordika, Matau's Aero Slicers became the Fang Blades. When the Hordika condition was reversed and Matau was restored to Toa Metru form, the Fang Blades reverted to Aero Slicers.
- What did the Aero Slicers become after Matau became a Turaga?
- When Matau and the other Toa Metru sacrificed their Toa Power to restore the Matoran of Metru Nui, Matau became a Turaga and his Aero Slicers transformed into the Kau Kau Staff, his Badge of Office. The staff was named after the cry of a Brakas Monkey and did not retain the flight function.
