The Toa Hordika set out to find airship parts, Kanoka disks and Kanohi masks for the trip back to the island up above. Vakama, Onewa, and Nokama all find evidence that they were not really meant to be Toa- the six Matoran who found the six Great Disks were. Krahka returns to fight Roodaka, but loses. Roodaka has her plant evidence that the Hordika were not the true Toa. Rahaga Iruini reveals to Matau that he and the other Rahaga were once Toa. Soon Sidorak summons a army of Visorak and a Zivon to kill the Toa and Rahaga. Tahtorak and Krahka come to fight it, but they are sucked into the Zone of Darkness with a Kahgarak. Roodaka and Sidorak plan their next move while the Toa Hordika share their evidence that Makuta knew Lhikan was going to pick the destined Matoran, but made him pick Vakama and the others.
