On a tropical Island called Mata Nui , six Toa heroes wash ashore in six Toa Canisters . After building themselves up , they discover their Kanohi masks and their elemental powers : Fire , water , stone , earth , air and ice . The Toa , named Toa Mata , each meet the Turaga , the elders of each village , or Nui , on Mata Nui . Eventually , they meet each other and discuss the next course of action . They begin to search their own five other masks , hidden on Mata Nui . Each mask that they found had the powers of one of the other Toa Mata ' s masks . They encounter dangerous Rahi , animals which attack them during their quest , and learn about Makuta Teridax . As the Toa collected their masks , they head for Kini - Nui to receive their Golden Kanohi which give them the abilities of all six masks in one mask , without the need to summon the other masks of power . They travel to Mangaia , Makuta ' s lair , to face him . The Toa Mata fuse together to form Akamai and Wairuha , battling a horde of Manas as they move towards Teridax . Being seperate again , they begin to battle Makuta in his Vortex form , one of his many forms he can take . But the Toa don ' t manage to defeat him and are teleported to Kini - Nui again . Takua , who followed the Toa , discovers the Bohrok as they begin to hatch . He escapes to the Ta - Wahi beach . 2002 . Insectoid creatures called Bohrok are awakened and rampage over Mata Nui to destroy everything they can see . The entire village of Le - Koro is overrun by the Levahk , who replace their masks with Krana , living beings which control the Bohrok or the wearer . Lewa hears the news of his village being overrun and goes to help . He soon discovers it is a trap as Turaga Matau greets him by replacing his Mask of Power with a Krana . Lewa and the village are saved by Onua and a group of Onu - Matoran in Boxor vehicles , built from Bohrok parts . The Toa originally believed that the Bohrok were otherworldly beings . However , when Tahu and Kopaka discover and enter a Bohrok nest , they discover that the Bohrok came from under Mata Nui . They leave to join with the other Toa and enter the Bahrag ' s lair . By placing all collected Krana in special niches , the Toa Mata unlock a passage to six Exo - Toa , armored and armed suits that the Toa can wear . They begin to battle the Bohrok queens Cahdok and Gahdok , but soon realize that the suits hinder their elemental powers , which they need to defeat the queens . After shedding their armor , they manage to defeat the Bahrag by encasing them in Protodermis . Suddenly , the ground begins to move and the Toa fall into energized Protodermis , transforming them into Toa Nuva , improved forms of themselves . They manage to escape the collapsing roof . 2003 . After the Toa Nuva imprisoned the Bahrag queens , six elite Bohrok , called Bohrok - Kal , are awakened and plan to defeat the Toa Nuva . They steal their " Nuva symbols " , which results in the Toa Nuva losing their elemental powers . The Toa find out on the new group of Bohrok and join together to recover another six sets of Kanohi masks . They battle the Bohrok - Kal , Lewa , Gali and Kopaka even merging into Wairuha Nuva to stop three Bohrok - Kal . But they also merge into a Kaita , Bohrok - Kal Kaita Ja , and defeat the Toa . The Bohrok - Kal eventually travel to the Bohrok Nest with the Nuva Symbols . The Toa follow them and witness the Exo - Toa fighting the elite Bohrok to guard the " Nuva Cube " . The Exo - Toa are defeated and the Bohrok - Kal are ready to fit the Nuva symbols onto the Nuva Cube to awaken the Bahrag and release the Bohrok swarms again , just as Tahu uses the Kanohi Vahi to slow down time around the Bohrok - Kal . But their Krana - Kal turn silver , protecting them from this threat . The Toa Nuva then let their powers flow through their Nuva Symbols , increasing the powers of the Bohrok - Kal . But that power is too much for them and they are destroyed by their own power . The Toa recover their symbols and the Krana - Kal and leave the nest . The Matoran celebrate " Naming Day " and rebuild themselves from their old , small to a bigger , stronger body . Takua and Jaller discover a carved stone in an underground cave and melt it in lava , revealing the Mask of Light . He hands it to the Turaga , who tell them they have to go on a quest to find the seventh Toa , the Toa of Light . Makuta , sensing this event , releases six Rahkshi to stop the pair finding the seventh Toa . Shortly after leaving Ta - Koro , the Rahkshi attack the village , destroying it and poisoning Tahu . Meanwhile , the two travel to Le - Wahi and are attacked by an ash bear , but are saved by Lewa . He travels with them to Ko - Wahi and they meet Kopaka , but the Rahkshi arrive and the three have to flee . Kopaka defeats them by plunging them into a sea and freezing it . The pair travels to Onu - Koro , where Takua meets Teridax , who tries to convince him to give him the mask . Takua refuses and joins with Jaller but due to a misunderstanding they part and go separate ways . As Jaller arrives in Onu - Koro , the Rahkshi Kurahk , Vorahk and Turahk attack the village . Takua notices this and joins Jaller to flee . The Toa Nuva join the fight against the sons of Makuta . Tahu gets hit by Kurahk ' s staff and turns against the Toa , just before Kopaka freezes him . They can stop the Rahkshi for a short while and flee Onu - Koro too . In the jungle , Kopaka and Gali manage to cure the poisoned Tahu Nuva . In the meantime , Takua and Jaller reach the Kini - Nui temple and are ambushed by three Rahkshi . The Toa arrive and begin to battle them . Jaller sacrifices himself from preventing Turahk attacking Takua . Takua puts on the Mask of Light and transforms into Takanuva , the Toa of Light . He easily destroys the Rahkshi and builds himself a vehicle to travel to Makuta ' s lair . Inside , he battles Teridax in a Kolhii match . In a struggle , they both plunge into a pool of energized Protodermis . Takutanuva is created , opens the gate to Metru Nui , the city beneath Mata Nui , and brings Jaller back to life . As soon as everyone is on the other side of the gate , the weak Takutanuva lets the gate crush him . Only the Kanohi Avokhii remains and Makuta is thought to be dead . Turaga Vakama reveals that the Toa Nuva were not the first Toa to be in existence . He tells the history of Metru Nui . The Toa heroes of this city were none other than the Turaga of Mata Nui , in stronger Toa - forms . 2004 . The 2004 - 2005 story is told by the Turaga to the Toa Nuva , and happened 1 , 000 years before the events on Mata Nui took place . In the city of Metru Nui , a Toa named Toa Lhikan gives six Matoran six Toa stones . The last one is delivered to Vakama , a Matoran crafter . Suddenly , two Dark Hunters , Nidhiki and Krekka , ambush Lhikan . He is imprisoned , but Vakama escapes . The six chosen Matoran go to the Great Temple and meet each other , being transformed into Toa Metru by the stones . Vakama receives a vision , telling him to find six great Kanoka Disks and the Toa team set off to look for them . They eventually find them and travel to the King Root of the recently unleashed Morbuzakh plant , which is damaging the whole city . The Toa Metru defeat the plant and travel to the Coliseum , a Skyscraper positioned in the middle of Metru Nui . They meet Turaga Dume and present him the disks to prove they were indeed Toa , not knowing that Dume is under the influence of Makuta Teridax . Dume falsely arrests them for killing Toa Lhikan and captures Whenua , Onewa and Nuju . The other three Toa can flee through chutes . Turaga Dume orders Nidhiki and Krekka to follow the Toa and capture them . They see the Toa using the chutes and fly to a chute station to reverse the direction of the flow . The three Toa escape though the chute and land on the ground of Ko - Metru . Inside a prison , Nuju , Whenua and Onewa meet an unknown Turaga , who instructs them in finding their mask powers . After trying several times they find them and break out of the prison . In Ko - Metru , Vakama finds out that the Great Disks can fuse together , creating the " Disk of Time " . The group head to Po - Metru where they are attacked by Nidhiki and Krekka . The attack is interrupted by a herd of Kikanalo . Nokama discovers her mask power of translating languages and arranges a trip on the Kikanalo to the Canyon of Unending Whispers . They find a legion of Vahki , police enforcers of Metru Nui . Since the Toa Metru were not working and were actually doing somewhat illegal tactics according to Vahki law , they were public enemy # 1 . The Toa Metru and Kikanalo battle the Vahki , Nidhiki and Krekka , with Matau discovering his mask power of illusions . The three Toa finally enter the passage and meet the other three Toa and the unknown Turaga . He reveals himself as the captured Toa Lhikan , as a Turaga . The Toa Metru discover " Matoran Spheres " with all of the Matoran in them . Teridax , disguised as Turaga Dume , ordered the Matoran to enter the pods to put them in deep sleep for many years until they had their memories wiped , where he would then reawaken them all and then introduce himself as their new leader . The Toa find a drilling machine and drill themselves to the surface , as the " Great Cataclysm " occurs . Teridax reveals himself to the Toa and absorbes Nidhiki , Krekka , the hawk Nivawk and the energy of the Coliseum , forming himself a body . The Toa Metru can escape in the Silver Sea and head for the Great Barrier . In the meantime , Vakama creates the Kanohi Vahi , the great Mask of Time . Teridax follows them and confronts Vakama , who uses the Vahi to slow down Teridax ' s shadow hand . He is saved by Turaga Lhikan , who is severely wounded and dies in Vakama ' s arms , who then at last discovers his mask power , invisibility . He manages to trick Teridax to grab a giant rock with his shadow hand , which crushes him . The Toa Metru finally seal him in a Toa seal and return to Metru Nui , intending to bring the Matoran to the Island of Mata Nui . 2005 . Continue their story as the Toa Metru , the Turaga tell how they returned to Metru Nui to find the city damaged and full of green webs . They are attacked by a group of spiderlike creatures , called Visorak . The Visorak wrap them into cocoons and transport them to the Coliseum , which is now under control of Visorak - leader Sidorak and his queen Roodaka . She convinces him to have the Toa Metru mutated , rather than kill them . Sidorak agrees and Roodaka orders the Visorak to set them free after they are transformed into Toa Hordika . After discovering their mutation , the Toa Hordika meet the " Rahaga " , also mutated Toa heroes . Norik tells them they had to find the being Keetongu , which is the only creature who can reverse their mutation . Vakama , slowly getting angry about himself not being able to be a good leader , leaves the Toa Hordika . However , since he has no fighting experience with his new body and weapons , he quickly gets caught by Visorak , who transport him to Roodaka . She promises him a good position as a leader of the Visorak horde . Vakama realizes that that is just what he needs and turns against his former Toa team . Meanwhile , the other Toa and the Rahaga travel to the Great Temple and find a scroll to locate Keetongu . As the Rahaga are inside , Vakama sneaks in and captures all Rahaga but Norik . As the Toa Hordika have enough of waiting outside they go in and find Norik under a pile of Rock . After digging him out , they journey to the place Keetongu inhabits , told to " " follow the falling tears until they reach the sky " " . Roodaka notices Keetongu climbs up the Coliseum , so she tells Sidorak to finish him . But Sidorak is revealed as a coward only good at commanding . Roodaka reveals her plan to overthrow Sidorak and leaves him alone with Keetongu , who then smashes Sidorak under his fists , killing him . Roodaka appears on the battlefield and claims her victory , just as Vakama then reveals he has returned to his Toa team . They Toa Hordika fire an elemental blast at her , hitting Makuta ' s stone in her armor , which releases Teridax from his protodermis cage and teleports Roodaka away . Keetongu transforms the Toa Hordika back to Toa Metru , who then rescue the rest of the Matoran to the surface to the newly formed island Mata Nui , which they named in honour to the Great Spirit . As they release the Matoran from their spheres , the Toa Metru transform to Turaga and begin to inhabit the island with the Matoran . 2006 . Returning from the Turaga ' s tales to the present day , The floating world of Voya Nui is introduced . The Matoran of Voya Nui already suffered from Hunger and other problems . As they saw Toa Canisters arriving , they hoped their problems were over . However , the Canisters actually contained the Piraka , once members of the Dark Hunters . After finding out the Matoran ' s hopes , they pretended to be Toa heroes , but a small group of Matoran grew suspicious . Then the Piraka enslaved and transformed the Matoran , except the small group , who fled . The Piraka continued with their plan to find the fabled Kanohi Ignika , Mask of Life by draining the lava of the volcano , Mount Valmai , in where the mask was hidden . Meanwhile , the Great Spirit Mata Nui is dying . To save his life , the Toa Nuva travel to Voya Nui to find the Mask of Life . After arriving on the island , they are quickly defeated by the Piraka . Another group of Matoran , this time from Metru Nui , are given the task to save the captured Toa Nuva . They are guided partway by Takanuva , who agrees to follow them only because he feels it was safer if he went along with them . Following them along the way is the Ignika , psychically tracking them as they journeyed into Karzahni ' s realm , where no Light can penetrate . Takanuva woefully waves goodbye to them as they go forward without him , and he travels back to Metru Nui . Once inside , Karzahni gives them new Kanohi and takes their old ones , except Kongu , who uses a Suletu ( Mask of Telepathy ) , he finds along the way instead . Once there , they meet a Matoran of Light who tells them of the World that Feeds the World , a mystic place where he came from . Karzahni thought this Matoran died before , but he was really hiding in relatively peaceful areas , and he built a new set of Toa Canisters . The Matoran from Metru Nui rush into them and escape , all the while Karzahni had decided that there is far more to the world than his realm and Artakha , so he must destroy it himself . During their journey , their canisters are struck by the lightning of the Red Star , transforming them into the Toa Inika . They battle the Piraka but they escape , traveling towards the location where the Ignika is hidden . The Toa Ignika follow them , encountering Protodax and Umbra , defeating them . Finally , the Piraka reached the Chamber of Life and found the seventh Piraka , Vezon . He had found the Ignika before the Piraka had , but on contact , the Ignika fused to the back of his head . It also connected him to a Fenrakk spider . Meanwhile , Axonn meets his former friend Brutaka , who knocks him out . After healing from his wounds , Axonn travels to the Piraka Stronghold to battle him again . This time , he defeats Brutaka , who is taken away by the Order of Mata Nui member Botar . Vezon easily defeats the Piraka and nearly does so with the Toa Inika , which arrived shortly after . But they manage to knock Vezon and Fenrakk into the lava , only to see Vezon emerging with an even stronger enemy , the Kardas dragon . During the continued battle , Toa Jaller fires a special Zamor Sphere at Vezon and Kardas , trapping them in a stasis field . Toa Matoro was able to remove the Ignika from Vezon ' s head , but the stasis field dissolved and Kardas launched a fire beam which hit Matoro , causing him to loose his grip on the mask . It flies up the staircase with the Toa Inika in pursuit . The mask flies out of the chamber and into the waters that surround Voya Nui . As Toa Hahli swims after it . She faints underwater , but is rescued by a Matoran who comes from below . Dying in the Inika ' s arms he tells them to help Mahri Nui , the City under the sea . The Toa Inika join the Matoran , Toa Nuva , Axonn , and Botar with Brutaka . Axonn opens a gate to the Cord , in which the Toa Inika can travel to the seabed . 2007 . The story introduces the evil Barraki warlords , who ruled distant lands in the world of Metru Nui . They had once gained so much power that they almost challenged Mata Nui ' s own rule . But Makuta Teridax and his allies challenged them in a battle , capturing their lands and imprisoning them . However , Botar arrived and took them to a place called the Pit , a place the Barraki inhabited for the next 80 , 000 years . During this time , a landmass broke off Voya Nui and sank into the sea , pulling several Matoran with it . This event was known as the Shattering . The landmass comes to a halt right over the Pit , smashing it open and freeing the Barraki , although they could not travel to the surface . The Matoran , having lost their memory of Voya Nui , begin to harvest the air bubbles which were created by the sinking landmass . They name their city " Mahri Nui " . In the present day , the Ignika plunges into the sea , heading toward Mahri Nui . The Toa Inika follow it , only to realize that they cannot breathe underwater . Axonn opens a gate to the cord , a massive stone cord connecting Voya Nui and Mahri Nui , revealing a passageway to the sea . The Ignika is discovered by a Matoran named Kyrehx who in turn gives it to Dekar . He learns about its power and decides to destroy it . Somewhere else , a Matoran named Defilak is questioned by the Barraki Pridak , who wants to find out where the mask is . The Kanohi Ignika sends out an energy blast , which transforms the Toa Inika into Toa Mahri . It also transforms Dekar into a clone of the dead pit jailer Hydraxon , who had perished during the shattering . The mask , now in the possession of the Barraki , is given to Nocturn to guard it . But he gets bored and realizes he can kill everything he touches , an effect of the Mask of Life . He leaves , not noticing a Gadunka which took refuge there and is now growing bigger . Toa Matoro finds out that a Maxilos robot carries the spirit of Makuta Teridax . Hydraxon meets Nocturn and defeats him , finding the mask . He attempts to destroy it but is stopped by Toa Hahli . The Toa travel in the Toa Terrain Crawler , given by Axonn , to battle the Barraki and get the Ignika . Maxilos and Hydraxon meet in a fierce battle . The Toa destroy the Cord which once attached Voya Nui to Mahri Nui . Voya Nui begins to sink towards the hole it made as it once rocketed up to the surface . Matoro chooses to sacrifice himself to save Mata Nui ' s life . He swims after the Voya Nui landmass and overtakes it just before it shuts the hole . Matoro puts on the Mask of Life and begins to dissolve , teleporting his Toa team to Metru Nui . The Ignika releases a blast of energy which awakes Mata Nui from death . The Ignika , which has turned silver , falls into the dome of Karda Nui and lands in a swamp . 2008 . 2008 features the return of old favorites : The Toa Nuva . This time , however , they are released in their Adaptive Armor forms , which gives them new weapons and masks shapes , being sent to Karda Nui . There , they form two groups , the Phantoka and the Mistika . The Phantoka have to save the Matoran of Karda Nui , confronting blinded Makuta and transformed Matoran . They have to find a way to transform the Matoran , defeat the Makuta and save Mata Nui ' s life . Being used by former Toa Matoro , the Kanohi Ignika falls into the " Swamp of Secrets " , creating itself a body and a Skyboard to discover its destiny . Takanuva arrives at Karda Nui . He learns about the Matoran , their problem and what has to be done . Takanuva has to find a cure for the infected Matoran , before the energy storm begins . Meanwhile , the other team , the Mistika have to recover six keystones with the instruction on how to save Mata Nui . They are confronted by another group of Makuta , this time in mutated forms . During the fight , they find all pieces and fit them into the spherical structure of Karda Nui , the Codrex . The Toa Nuva , now all rejoined again , travel into it , not knowing that they are followed by Antroz . Inside , they discover three vehicles to be used to awake the Great Spirit . Before Kopaka can mount the Jetrax T6 , it is hijacked by Antroz , which he uses to fly out of the codrex . Toa Pohatu , piloting the Rockoh T3 and Toa Lewa , piloting the Axalara T9 , are left in pursuit . Toa Ignika meets with the other Toa Nuva and agree that he must sacrify his body to awake Mata Nui , just as Matoro did . He flies into the Codrex , dissolving slowly until only the Ignika is left . It falls down to the bottom , activating its purpose and starting a massive energy storm . The Toa Nuva , now claiming the Jetrax T6 due Antroz ' s depart , race away with Takanuva and all Av - Matoran , being transformed back by Takanuva and the help of a creature called " Klakk " . The Makuta are left behind , being killed by the energy storm . The Toa Nuva make it out of Karda Nui safe , just before Mata Nui awakes . They are welcomed by the Matoran of Metru Nui and the Turaga . But Teridax has taken over the body of Mata Nui , long before the Toa Nuva awaked the robot . He drove out the spirit of Mata Nui as Matoro sacrified himself . As the Toa Nuva awaked the robot , they accidentially awaked Teridax . He banishes Mata Nui into the Ignika and shoots it into outer space . He begins his reign in the Matoran Universe , not knowing that the Kanohi Ignika is on a direct course to the planet Bara Magna . 2009 .

A new storyline begins on the " mythical island of Okoto " , whose resident Okotans are Matoran / Agori like villagers who wear masks forged by the brother Mask Makers Ekimu and Makuta . Ekimu wore the Mask of Creation and Makuta wore the Mask of Control , but Ekimu ' s masks were favored over his brother ' s , causing Makuta to become filled with jealousy and bitterness . As a result , he broke a sacred code of the Mask Makers and forged the Mask of Ultimate Power , which contained the powers of all six of Okoto ' s elements : Fire , Ice , Jungle , Water , Stone , and Earth . When he donned the mask , its power overwhelmed him , and Ekimu was forced to knock it from Makuta ' s face : the mask then exploded , releasing energies that drew Makuta and Okoto ' s capital city into the Shadow Realm and devastated Okoto , utterly changing its terrain . Ekimu was rendered comatose , but his body spoke the words of a prophecy by which the legendary Toa , heroes with the powers of the Elements , could be summoned in the time of Okoto ' s greatest need . Ekimu ' s body was laid to rest in a tomb by the Protectors , whose descendants protected the island and hid the masks to be worn by the Toa until the island was invaded by the Skull Spider s . They then gathered and spoke the Prophecy of Heroes to summon Tahu , Kopaka , Lewa , Gali , Pohatu , and Onua to the island before leading them to their Golden Masks of Power . The Toa would then join forces to defeat the Lord of Skull Spiders , before entering the City of the Mask Makers to find and revive Ekimu . After facing the Skull Warrior s , Skull Slicer , and Skull Scorpio s , the Toa awaken Ekimu and then must face the evil Skull Basher and Kulta , the Skull Grinder , who has stolen Ekimu ' s Mask of Creation .

The Element Lords were a group of Glatorian and one Skrall leader who were fused with their tribe ' s respective elements by the Great Beings so that they could rule over their peoples , leaving the Great Beings free to pursue their experiments and other pursuits . However , when Energized Protodermis began leaking from within the planet , the Element Lords became obsessed with possessing it and led their people in a massive war . The conflict eventually ended when Spherus Magna was shattered into three smaller worlds , and the Element Lords were left trapped for tens of thousands of years . However , they eventually escaped and , with the protodermis lost to them , sought to penetrate the Valley of the Maze to gain the power of the Great Beings . Great Beings . The Great Beings were a group of highly intelligent and powerful beings on the planet Spherus Magna ; they ruled it for a time before creating the Element Lords to do so in their place . When the Core War broke out the Great Beings attempted to stop it , but were unsuccessful ; they thus created the Baterra in an effort to end the conflict . After learning that the planet would be broken up , the Great Beings created Mata Nui ' s giant robot body , with the intent that he would return and restore the planet to its unified state . However , they were unable to complete all their plans , and came to be regarded with contempt among the denizens of Spherus Magna and were blamed for the catastrophes that had befallen that world . Unbeknownst to anyone , one of the Great Beings had infiltrated the robot by taking the form of the Matoran Velika , and now seeks to eliminate all the powerful beings of the former Matoran universe .
