Frequently asked questions
- What is the Hook Blade in Bionicle?
- The Hook Blade was a curved cutting weapon issued to the senior ranks of the Skull Army during the Skull Creature campaign on Okoto. It could cut through solid stone, and like most Skull weapons it doubled as a tool for grabbing masks.
- Who used the Hook Blade?
- Kulta carried a Hook Blade as the secondary weapon to his Mask Stealer Staff. Skull Slicer, the reanimated arena champion who guarded the Arena in the City of the Mask Makers, carried three of them.
- How does the Hook Blade take masks?
- The blades are listed as melee weapons that could also be used for mask grabbing, and their hooked shape suits that job. The story never shows exactly how a Hook Blade took a mask; Skull Slicer captured Lewa's Golden Mask with his separate Mask Grabber.
- How was Skull Slicer defeated despite his Hook Blades?
- Skull Slicer took Lewa's Golden Mask of Jungle with his Mask Grabber and forced the other Toa to play the arena game on its raised pillars. Pohatu pinned and disarmed him, Kopaka freed Tahu and recovered Lewa's mask, and Onua won the game by smashing a lever that dropped the floor out from under Skull Slicer and brought down the Arena. His blades were lost in the collapse, and whether he survived is unknown.
- What happened to Kulta's Hook Blade?
- Kulta lost his Hook Blade after Ekimu defeated him at the Forge of the Mask Makers. He was separated from his gear and locked in a cell in the city, and the blade is not among the weapons he takes up in the later fighting.
