Six mighty heroes – the Toa – arrive on a tropical island to find a land under siege. The Great Spirit Mata Nui has been cast into an unending sleep by the evil Makuta. Now Makuta is attacking the island's Matoran villagers with vicious Rahi beasts. The Toa must combine their skills and elemental and mask powers to defeat Makuta and restore peace to the island.

In the second story, The Toa return to the island named for Mata Nui to find it is being overrun by mechanical insects called Bohrok. These Bohrok have been unleashed by Makuta and are rapidly destroying trees, mountains, rivers, villages and anything else in their path. After a long, difficult battle, the Toa are able to defeat the queens of the swarms and end the Bohrok threat … for now. During the fight, the heroes are transformed into Toa Nuva, with new armor, new weapons, and new Masks of Power.
 
The Toa Nuva suffer a mysterious loss of their powers which threatens their very existence. It's the work of the Bohrok-Kal, a special squad of mutated Bohrok who seek to free the swarm queens and unleash the Bohrok again. With the help of the legendary Mask of Time, the Toa Nuva are able to defeat the Kal.

Meanwhile, a Matoran village named Takua has stumbled upon the long-hidden Mask of Light. He and his best friend, Jaller, are sent by the village elders, the Turaga, to find the Toa to whom the mask is destined to belong. But Makuta unleashes twisted creatures called Rahkshi against the island in an effort to stop the Toa of Light from coming into being. After many defeats, the Toa Nuva unite to stop the Rahkshi with the help of Takua, who dons the Mask of Light to become Takanuva, Toa of Light. Takanuva challenges Makuta in battle, a fight which leads to the discovery of a huge underground island city – Metru Nui.
