BIONICLE Legends 1: Island of Doom

Island of Doom is the first Bionicle Legends and came out 2006.

As the Matoran were repairing Metru Nui, Turaga Dume consulted with the Toa that Mata Nui wasn't just sleeping, he was dying. The only way to save the Great Spirit was to find the Kanohi Ignika, the Mask of Life. But it can only be found on Voya Nui. The Toa Nuva set out in similar canisters that brought them to Mata Nui with Takanuva guarding Metru Nui.

Six rogue Dark Hunters called Piraka appear on the island of Voya Nui, where the resident Matoran mistake them for Toa. However, they have their own agenda, seeking out a legendary treasure that threatens to unlock an ancient evil. The Piraka used Zamor spheres made from antidermis to enslave the Matoran after fighting a fake monster. Only six were spared from the chaos and formed a rebellion. The Piraka defeated the Toa Nuva. Zaktan ordered that their masks and weapons be taken and the Toa thrown into the volcano. Back in Metru Nui, Turaga Nokama tells Jaller about what was going on. After she left, Jaller sought the best Matoran to go save the Toa Nuva.
