Trials of the Toa

"There's so much we don't know about our past. Maybe whoever built this maze has something to do with us, or we have something to do with them."

- Onua and Gali talking about the Labyrinth where the Mask of Control is hidden.

'''The day after the Toa found peace with their creatures, the 6 heroes are on their way to find the great Mask of Control before Umarak does. At the start of their journey Umarak attacks to see which Toa has the weakest bond with their creature which works for him perfectly. Once the Toa arrive to the Labyrinth they start to question their past. After finding the realm they all unite with their creatures except Pohatu which leads to Umarak stealing Ketar and taking the Mask of Control. While expecting the Toa to come after him, he does something cruel that made him get away with the Makuta's mask. After Umarak retrieves Makuta's mask, being a huge rebel he is, he puts it on and Makuta gets full control over Umarak making him Umarak the Destroyer.'''

Plot
The episode starts off with Tahu flying through the sky and fooling around. Onua stops him by rising an earth pillar which makes Tahu crash into it. We see Umarak talking to Makuta who is shown as a shadowy fire. Umarak talks how he will take the creature from the Toa by finding their weakest link. After the Toa and their Creatures continue on their journey, the Creatures feel like something bad is lurking. Tahu gets shot by an arrow whom which he throws it on the ground next to Ikir and it turns into a Shadow Trap and bites Ikir on his leg. Umarak quickly shows himself to the Toa. Akida notices him and tries to hit him with her water guns on her back but she misses and Umarak shoots almost hitting her thanks to Gali who saved Akida. Tahu and Ikir unite and try to take down Umarak but he escapes. Umarak comes behind the Toa and shoots the mountain so the rocks would fall on all of them. All the Toa help their creatures except Pohatu who runs off leaving Ketar on his own. After the creature almost getting squished, Onua helps Ketar which Umarak notices and sees Pohatu as he has the weakest bond with his Elemental Creature. Umarak continues to watch them fight pathetically and then makes his own shadow versions of himself and sends it on the Toa. Ketar wanting to unite tries to get Pohatu's attention but he tells him to go somewhere else. Umarak has seen enough and leaves. Toa are confused and Lewa suspects he's up to something because hunters never run away. The Toa continue on their journey to the maze and Umarak follows them. At the top of the mountain, Gali notices the Labyrinth on the other island. The 6 Toa and the Creatures go down the mountain to the beach to see the clearer look of the Labyrinth. Tahu thinks they all raced to the beach and declares himself a winner. The Toa and Creatures unite and find ways to get to the other island. Everyone goes except Pohatu, Ketar and Onua because he was waiting for Pohatu. Pohatu goes off without Ketar which Onua noticed and so he brought Ketar with himself making a huge bridge to the other island.
