Frequently asked questions
- What were the Maxilos robots?
- The Maxilos robots were a line of autonomous guard units designed by Artakha and operated by the Order of Mata Nui. They served as auxiliary guards at The Pit, the Order's deep-sea prison, working alongside the warden Hydraxon to contain the most dangerous inmates in the Matoran Universe.
- What weapons did the Maxilos robots carry?
- Each Maxilos carried a Twin-Bladed Black Fire Sword as standard issue, along with a Cordak Blaster. The Energy Hound species was also paired with the units, and Spinax was assigned to a Pit-stationed Maxilos by Hydraxon.
- How did Teridax take control of a Maxilos robot?
- After the Great Cataclysm broke the cells, most Maxilos units scattered in pursuit of escaped prisoners, but one remained near the former Pit. Teridax descended to The Pit in his Antidermis form, located the remaining unit, and inhabited the body, operating it as his physical form throughout the Mahri Nui campaign.
- How did the Teridax-possessed Maxilos manipulate the Toa Mahri?
- The reconstituted Hydraxon mistook Matoro for a fugitive and locked him in a cave with Maxilos and Spinax, where the robot revealed itself to Matoro as Teridax. Teridax instructed Matoro to conceal his identity from the other Toa Mahri and manipulated the team's mission for the remainder of the campaign, while the other Toa accepted Maxilos as a cooperative Pit guard.
- What happened to the Teridax-possessed Maxilos?
- The Maxilos body sustained severe damage in conflict with the resurrected Hydraxon and the Barraki, and Teridax abandoned the shell. Hydraxon later located the body, confirmed no trace of Teridax's essence remained, found it beyond repair, and discarded the remains.
