Bionicle VII: Sea of Darkness

Bionicle VII: Sea of Darkness (also known as Bionicle 7 and Bionicle Ignition 2: Ruins of the Lost in Europe) is a 1987 Vlokuzuian science-fiction action tokusatsu superhero film. It is the thirteenth Technic Heroes installment and the seventh Bionicle installment.

Plot
The film starts straight after the events of Bionicle VI: Island of Doom, Ryota Maximino, Akita's father hires the six teenagers as the workers of the MURC (Mahri Underwater Research Centre), near Abeta.

13 months later, the Mask of Life's descent ends in the deeps of Mahri near the MURC, an underwater basement. Upon sight, it becomes an object of interest to the people who are working for MURC as well as the Barraki; six former warlords sent to the Pit (a prison that sits on the lip of the city) after their crimes as part of the League of Six Kingdoms.

But after the Pit was damaged in the Great Cataclysm, they escaped into the surrounding ocean and were mutated by its mutagen waters. Believing the mask can change them back so they can rule the Kingdoms once again, the Barraki battle one another for possession of the Ignika.

Meanwhile, the Toa Inika continue their descent through the stone cord where they battle Vezon and an army of murderous Zyglak. Upon reaching the depths of the sea, the Mask of Life transforms the heroes into the water-breathing Toa Mahri - complete with new masks and weapons.

The team engage in combat with the Barraki and their aquatic Rahi armies upon arrival, but in the midst of the battle, Matoro is imprisoned in the Pit by a robotic Maxilos guard that reveals itself as Makuta Teridax, who possessed the robot after his essence followed the Toa through the stone cord.

He informs Matoro that Mata Nui's life can only be saved if the Toa shatter the cord, and although not trustful in the villain's words, he relays the information to his team-mates. They agree and evacuate MURC members from the secondary basement before proceeding to destroy the cord; sending one of Mahri's islands plummeting into the ocean and demolishing MURC's secondary basement in the process.

But by the time the Toa Mahri retrieve the Ignika, Mata Nui dies. Believing there's still hope, Matoro - the one person who can touch the Ignika without becoming cursed - races towards a hole in the seabed with it before Voya Nui descends to close it, leaving his team to continue battling the Barraki.

Once in, he falls through a waterfall in what resembles a large cave and hears a voice from inside the mask telling him to put it on. In doing so, Matoro learns of the Ignika's history and how to use it to resurrect the Great Spirit.

Now knowing it is his destiny to sacrifice himself to save the universe, Matoro uses the Ignika's powers to teleport the Toa Mahri back to El Kadsre and make them amphibious before the mask turns his body into pure energy that saves the Great Spirit. Meanwhile, the Maxilos body that Teridax inhabited is found badly damaged after a ferocious battle with the Barraki's armies, and is so presumed dead. Mata Nui has been saved, but remains asleep.
