The Bohrok have been beaten. Or have they? Strangely transformed Toa with new weapons and armor will need all the power they can muster to defeat the Bohrok-Kal. A chase for stone symbols that hold the Toa Nuva’s elemental powers leads full circle to the Bahrag!
Energized protodermis pools beneath the Bahrag lair had swallowed up the Toa. The liquid mutates the six Toa heroes, making them more powerful than ever. Six figures emerge from the shimmering liquid, equipped with new masks, new armor, and new tools.
The Toa Nuva have arrived on Mata Nui.
After the imprisonment of the Bahrag, commanders of the Bohrok swarms, Matoran engineers have started using the Bohrok machines to clean up the mess they’ve made. Aided by small Bohrok Va helpers, the villages begin putting their homes and lives back in order. Little do they realize their peace is only temporary.
Six Bohrok-Kal, have emerged from their sleep to find and free Cahdok and Gahdok. They are far more intelligent than their cousins, and much more powerful. Their only problem: they have no idea where to find the Bahrag prison.
The super-Bohrok begin stealing mysterious tablets from the shrine of each village. These tablets embody the elemental powers of the Toa Nuva, who as yet have not mastered their new abilities. Nor do the Toa Nuva know that their elemental powers are in danger. They find out the hard way when the Kal steal each symbol, which causes the Nuva to lose the ability to use their elemental powers. The Toa Nuva must rely solely on their wits and mask powers to track down and recover each tablet with their symbol on it.
The Toa Nuva meet at Kini-Nui, where they are accosted by the Bohrok-Kal. Unlike regular Bohrok, these can talk, and talk they do. The Kal demand the Toa tell them where the Bahrag twins are held. Although the Nuva claim ignorance, the Kal fail to believe them and stun them into unconsciousness. Like the Bohrok swarms before, they do not harm the Toa or Matoran. They simply do what they must to meet their goal of freeing the Bahrag.
The chase begins. In addition to trying to find and vanquish the Bohrok-Kal, the Toa Nuva must find their Kanohi Nuva to match their new status. Eventually each Toa has their full complement of six masks each, and they track the Bohrok-Kal to where they feared the Kal would be: the underground prison of Cahdok and Gahdok.
Inside, the Toa Nuva are astonished to find a fight already going on… between the Exo-Toa and the Bohrok-Kal! But the Exo-Toa machines are losing, and are pounded to bits by the power of the Kal.
A small cube floats in the chamber before the protodermis prison. While the Bahrag scream encouragement, the Bohrok-Kal pick up the tablets containing the Toa’s elemental powers and step over the remains of the Exo-Toa. They are mere moments away from placing the tables onto the six sides of the cube, which is the key to the lock that holds the Bahrag. The Toa are too far away and without their powers, helpless to stop the Kal.
Desperate, Tahu Nuva uses the Vahi mask of time to slow time down around the Bohrok-Kal. They only have minutes, just enough time for Gali Nuva to come up with a plan and share it with her fellow Toa Nuva.
As the Bohrok-Kal come out of slowed-down time, the Toa Nuva link their minds to each of their tablets and trigger the raw elemental energy in them. The Bohrok-Kal, thinking to use the energy to rule beside the Bahrag, eagerly suck the energy from the tablets but can’t control the massive forces. Their powers manifest themselves wildly, and each Kal is overcome by their own greed. They are crushed, electrocuted, utterly destroyed.
Safe in their prison, Cahdok and Gahdok scream in frustration, but the Toa retrieve their elemental Nuva tablets and leave the Bahrag to their own company.
Cleanup begins once more in the villages of Mata Nui, even to the extent of creating a brand new kolhii field in Ta-Koro. But worse foes await the Toa Nuva and their Matoran charges…
