Frequently asked questions
- What happened in BIONICLE 17: Disks of Danger?
- The comic, also titled In the Grip of the Morbuzakh!, followed the Toa Metru as they recovered the Great Disks: the Ta-Metru disk from the Fire Pits, the Onu-Metru disk from the Archives, the Le-Metru disk from a Force Sphere, and the Ko-Metru and Po-Metru disks. With all six found, Vhisola's research pointed them to the Morbuzakh's King Root in the Great Furnace.
- How did Matau recover the Le-Metru Great Disk?
- Acting on information from his old rival Orkahm, Matau jumped into the Force Sphere carrying the disk as it passed through the Notch. Using his air powers, he escaped with the disk just before the sphere imploded.
- Is the rogue Tunneler in the comic?
- No. The Tunneler appears in the novel BIONICLE Adventures 2: Trial by Fire, where Vakama and Onewa combine their powers to form glass; the Tunneler absorbs it, becomes a creature of glass, and stops moving rather than shatter. In the comic, the Reconstitute at Random disk is used by Nuhrii against Morbuzakh vines in the Fire Pits.
- How did Onewa recover the Po-Metru Great Disk?
- The comic shows Onewa retrieving the Po-Metru disk only briefly. In Trial by Fire, he takes it from the top of an unstable statue and narrowly avoids being crushed when it falls.
- How was Ahkmou exposed as the traitor?
- In Trial by Fire, Ahkmou tries to run on the way to the King Root, and Onewa realises he was definitely the traitor and confronts him. Mystery of Metru Nui had already shown a Matoran striking a deal with Nidhiki to get the six Great Disks.
