2001

2001 was the beginning of the Bionicle universe. Mata Nui was an island paradise, until Makuta of Metru Nui threatened the island. He infected masks and put them on various Rahi, making them his loyal servants. Plants died, the skies darkened and his power ruled over the island. One day, six Toa canisters were launched to sea and drifted onto Mata Nui. The Toa inside were called the Toa Mata. They were Tahu, Onua, Lewa, Kopaka, Pohatu, and Gali. Along with the Matoran and the Turaga, they were set on a quest to find the Great Kanohi scattered around the island.

Later, they came to Makuta's lair, and they defeated him in battle by combining themselves into Toa Kaita. They had to defeat the Manas in the chamber, some of the most powerful and aggressive Rahi ever.

The Toa made Mata Nui return to normal, and all was well.
