Legends of Metru Nui

After their defeat of the Morbuzakh and the shape-shifting Krahka, the Toa Metru expect to be hailed as heroes. Instead, they are betrayed by someone they thought they could trust. Three of the Toa are arrested. In prison, they meet a mysterious stranger who helps them to escape, and to learn more about their new powers. The remaining Toa are forced to flee through the city, avoiding security forces and the Dark Hunters who try to capture them.
