Bionicle X: The Journey's End

Bionicle X: The Journey's End (also known as Bionicle 10) is the 1990 El Kadsreian science-fiction action tokusatsu superhero telefilm. It concluded Bionicle's story with a large-scale, climactic conflict between Mata Nui and Teridax, and all of their allies among the people of El Kadsre.

Plot
Mata Nui learns of Bara Magna's past, his creators the Great Beings, and his destiny to reunite the planet with its moons Aqua Magna and Bota Magna to recreate the once-plentiful Spherus Magna. He begins his quest by travelling through a maze occupied with booby-traps (using the map he found as a guide), where he uncovers an unstable power source.

After convincing the Glatorian and Agori to let him use the prototype robot that they use as their Mega-Village, Mata Nui places the power source, the Mask of Life and his spirit inside it, and as the vessel, begins the process of reuniting Bara Magna with its satellites.

Later, Makuta Teridax - in Mata Nui's old body - touches down on the deserts of El Kadsre after sensing Mata Nui's presence. Planning to conquer the planet and eventually the rest of the universe, he offers Mata Nui the chance to join him. He refuses, and the two robots do battle.

On the ground, several Rahkshi and Skakdi under Teridax's command exit the Matoran Universe via his heel, followed by Tahu, Takanuva and other Toa. The Makuta's forces are soon joined by the Skrall, who together, battle the Glatorian and Agori.

Meanwhile, the Mask of Life reduces Tahu into his original Toa Mata form so he can don the Golden Armor; a weapon originally devised to destroy the Makuta species if they were to ever betray Mata Nui. Teridax notices and scatters the armor across the desert with an energy blast. With help from the Glatorian Gresh, Tahu and Takanuva retrieve the armor back from their enemies.

When Tahu bestows it, a wave of energy is unleashed that incinerates all the Kraata powering the Rahkshi armor, leaving the Skakdi and Skrall greatly outnumbered. Mata Nui notices Teridax's hesitation in sensing the loss of his Rahkshi and sees a chance to swing his body into the oncoming path of a rock fragment from Aqua Magna.

It crashes into the Makuta's head and damages the robot's core processor, killing the tyrant for good. Mata Nui completes his destiny of reforming Spherus Magna, but the strain is too great as his body plummets to the ground.

The Toa and Glatorian arrive at El Kadsre City to find Mata Nui speaking from inside the undamaged Mask of Life. He asks them to seek out the Great Beings as his final wish before deciding to stay dormant within the mask. The Toa, Matoran, Glatorian, Agori and all other beings from both worlds now begin a new life on Spherus Magna.
