Of all the awful Bohrok, the Pahrak are the most dogged and unrelenting, never, ever giving up until their work of devastation is complete. Their shields, if you can believe it, actually have the power to cause earthquakes, and the sheer might of their mighty limbs allows them to move massive boulders! In fact, no matter what the obstacle, the Pahrak can mash it and smash it to rubble without breaking a sweat. Remove their krana, however, and tame them, and they make very excellent workers.
Once the Toa are exposed to the mysterious energies of protodermis, they are transformed, stunningly, into the mighty Toa Nuva! With awesome new powers, awesome new armor, and awesome new tools, the Toa Nuva are confident that they are ready for any threat, no matter how dire, to their lovely island home. HOWEVER: will the unearthly abilities of the Toa Nuva save Mata Nui: or shatter it irreparably forever?
