Teridax

"Yes, I never noticed your entry, I must admit. But did you really think a pale and weak version of myself could stop me now?" "Weak? Stronger, I say, for I resisted the temptations you could not."

- Teridax and His Alternate, Reign of Shadows

Teridax, also known as "The Makuta" or simply "Makuta", was the original Makuta overseer of the Dome of Metru Nui. He successfully orchestrated a master plot to overthrow the Great Spirit Mata Nui and seized control of the Matoran Universe.

Pre-Metru Nui
Approximately 100,000 years ago, Teridax was brought into being by Mata Nui using the substance known as Antidermis on an island somewhere in the Southern Islands of the Matoran Universe. Like all other Makuta, he was created to be a member of the Brotherhood of Makuta, an organization tasked with maintaining order in the universe and serving the will of Mata Nui. Teridax became the most trusted lieutenant of Miserix, the leader of the Brotherhood. He also created numerous breeds of Rahi beasts, one of which was the Water Wraith. When the League of Six Kingdoms attempted to conquer the Matoran Universe, Teridax assembled a powerful army consisting of Toa, Exo-Toa, Rahkshi, and Rahi, to prevent them from accomplishing this goal. He then launched an attack against the assembled armies of the Barraki, and overwhelmed them with the ambush. Once the battle was over, Teridax demanded to see the Barraki. The Barraki offered to give their armies to the Brotherhood, and overthrow Mata Nui together. Teridax ignored their request, and prepared to have them executed. However, Botar arrived, and teleported the Barraki to The Pit. The Barraki's armies soon collapsed, and their fortresses were torn apart. Teridax, however, was influenced by the Barraki's idea to overthrow Mata Nui, and soon began developing his own evil intentions. When the Matoran Civil War occurred on the Island City of Metru Nui, Teridax was ordered to stop the fighting. Teridax locked the opposing armies in the Archives and unleashed the exhibits on them. After this, Miserix assigned the Makuta to protect various regions across the Matoran Universe, and Teridax was assigned to Metru Nui. Soon afterward, Teridax, with the knowledge Mutran had gained from Tren Krom, called a Convocation and announced his plan to overthrow Mata Nui to the assembled Makuta. Miserix was furious and attacked Teridax, forcing the Makuta to fight. Teridax eventually emerged victorious, and the rest of the Makuta supported him. Teridax claimed leadership of the Brotherhood and ordered Krika and Spiriah to kill Miserix. After the Makuta's evolution into beings of Antidermis, Teridax ordered the Nynrah Ghosts to be brought to Destral to modify the Makuta's armor. Under his leadership, the Brotherhood started to enslave Matoran, and even went so far as to steal the Kanohi Avohkii, the Mask of Light, from Artakha. They still pretended to be forces of good, however, and a team of six Toa Hagah were assigned to protect Teridax. The leader of the group, Toa Norik, soon discovered that the Brotherhood of Makuta had stolen the Kanohi Avohkii, and the Hagah rebelled against Teridax and his Brotherhood. In the ensuing conflict, they defeated many of the Brotherhood of Makuta's armies and also retrieved the Avohkii. Teridax himself battled them to a stalemate; however, Teridax was badly weakened and forced to retreat. The Toa Hagah were eventually mutated into Rahaga by Roodaka, but they were able to escape with the Kanohi Avohkii. Because several Dark Hunters, a large organization of bounty hunters, were guarding the base when the Toa Hagah invaded, Teridax wanted to execute them. "The Shadowed One", the Dark Hunters' leader, refused to allow such an event, and the Dark Hunters were removed from the base. Soon after the rebellion of the Toa Hagah, Teridax struck at Mata Nui, infecting the Great Spirit with a specialized virus that would cause his slumber roughly three-hundred years later.

Metru Nui
Teridax then launched his plot to capture the Matoran of Metru Nui, therefore making it impossible for Mata Nui to wake up. Before invading the city, he created a plant to get the Matoran in his grasp. He named it Karzahni after the ancient being. The plant was too powerful, and Teridax abandoned it. He later created the Morbuzakh for his deadly plot. He began his initial takeover by capturing the city leader, Turaga Dume, and placing him in a Matoran Sphere, casting the Turaga into a deep sleep. Using his shapeshifting powers, Teridax disguised himself as Dume, bringing in a pet Nivawk, whom he used to spy on the city. Following this, he also hired three Dark Hunters, Nidhiki, Krekka, and Eliminator. Nidhiki and Krekka were ordered to patrol the city, and follow any requests made by Teridax, and Eliminator was stationed outside the city. Teridax sent most of the city's Toa outside the city on missions, and they were quickly exterminated by Eliminator, leaving only Toa Lhikan to guard the city. Still posing as Turaga Dume, Teridax ordered Metru Nui's best Mask Maker, a Ta-Matoran named Vakama, to forge a Legendary Kanohi Vahi, Mask of Time, and present it to him. The Makuta was plotting to place all the Matoran in Matoran Pods. Their memories and strength would be removed slowly over the course of a few years, and Teridax planned to use the Vahi to speed up the process. Once the Matoran would awaken, he would claim himself their rescuer and ruler. Teridax became aware of Lhikan's growing suspicions, and that Lhikan would attempt to create more Toa. He ordered Nidhiki and Krekka to capture Toa Lhikan, and manipulated Lhikan's mind so that he would pick the "wrong" six Matoran to be Toa, in case the Toa was able to fulfill his destiny. What Teridax did not know was that Mata Nui had changed the stars to make him pick the right Matoran. Mata Nui also planted the right Matoran in his mind: Vakama, Nokama, Matau, Onewa, Whenua, and Nuju. Believing he had taken care of the Toa, Teridax released the Morbuzakh in the Great Furnace in Ta-Metru. The Morbuzakh plant's purpose was to drive the Matoran into the Coliseum, where the Vahki, order enforcement squad of Metru Nui, could capture them. Teridax was also told that the Dark Hunters had captured Lhikan, but not before the Toa had managed to deliver the Toa Stones. He then used Nivawk to spy on the Toa Metru as they turned into Toa. Teridax learned that the Toa were planning to collect the Great Disks to defeat the Morbuzakh, and to stop them, he told Nidhiki and Krekka to get the Great Disks before the Toa could succeed. They were unsuccessful, however, and the Toa both managed to collect the Great Disks and defeat the Morbuzakh. Despite this setback, the Brotherhood of Makuta leader adapted, and ordered the Matoran to report to the Coliseum where he used the Vahki to capture them. The Toa Metru then arrived at the Coliseum to give the great disks to "Turaga Dume" as a gift. Teridax rejected the disks, and proclaimed the Toa were impostors who had captured Lhikan. He managed to capture three of the Toa: Onewa, Whenua, and Nuju, but the others escaped. He deployed the Vahki, as well as Nidhiki and Krekka, after them. Despite the Toa on the loose, Teridax continued with his plan. He broadcasted a message to the Matoran to gather at the Coliseum. Once there, he had the Vahki place them all in Matoran Spheres. Shortly after the Matoran were imprisoned, all six Toa Metru and Turaga Lhikan arrived at the scene. It was then that Teridax revealed to them his true identity. Teridax then initiated the events that led to the Great Cataclysm, which spawned numerous problems across the Matoran Universe, as a result of Mata Nui's sleep. While the Toa Metru fled, Teridax absorbed Nidhiki, Krekka, and Nivawk, destroying their wills and using their mass to fuel his own transformation. While he absorbed them, the Toa Metru took six Matoran pods and fled the city on a Vahki Transport. Teridax pursued the transport, and engaged in battle with the Toa Metru at the Great Barrier. He claimed a spot high atop a cliff, and created large Protodermis pillars to try and stop the transport. Vakama had Nuju use his Kanohi Matatu to get him up to the point on the Great Barrier where Teridax waited. Once there, he removed the completed Kanohi Vahi from his pack. Impressed, Teridax offered the Toa the chance to join the Brotherhood, but Vakama refuse. Teridax then released a shadow hand in an attempt to finish Vakama, but Vakama activated the Mask of Time. Unable to control the Vahi, Vakama could not stop the oncoming shadow hand, forcing Lhikan to intervene. Teridax's shadow hand claimed Lhikan's shield, and the dark energy emitting from it killed the Turaga. While Vakama was mourning Lhikan, Teridax recovered the Vahi, which had been knocked away from Vakama. Before he could use it, Vakama launched a Kanoka to remove the mask from Teridax's grasp, and the Vahi fell into the sea. Furious, Teridax shot another shadow hand at Vakama, only to realize that Vakama had mastered his Kanohi Huna, which allowed him to become invisible. Teridax pursued Vakama across the Great Barrier, until he attached his hand to the Great Barrier itself. Unable to absorb the immense object, Teridax was drawn towards the cliff, slamming into it. Before he could recuperate, the other five Toa Metru united with Vakama and combined their powers to form a Toa Seal surrounding Teridax. Knowing that he could free himself with the same elemental powers that imprisoned him, Teridax let his mind wander, and eventually reached Roodaka, viceroy of the Visorak Horde, and Sidorak, King of the Visorak. He ordered them to take control of Metru Nui, and instructed Roodaka in secret to free him from his prison. The Visorak horde took over Metru Nui easily, and Roodaka took a small shard from the Protodermis prison. She then placed it in her armor, just over her heartlight. The Toa Metru returned to Metru Nui to rescue the rest of the Matoran, but were instead captured and mutated into Toa Hordika by Visorak Venom. Roodaka managed to convince Vakama to join her side, and persuaded Sidorak to give him command of the Visorak. The other Toa, with Keetongu and the Rahaga, attacked the Coliseum in an attempt to rescue Vakama. In the ensuing battle, Sidorak was killed by Keetongu. The battle abruptly ended when a giant Kahgarak, ridden by Roodaka, fired an energy blast that stunned the Toa Hordika long enough for the Visorak to close in. Vakama later appeared, turning over Matau, whom he had been fighting the whole time, to Roodaka. Following Matau's lead, the other Hordika fired elemental Rhotuka at Roodaka, which she merely laughed at. Vakama, however, reaffirmed his loyalty to his friends, and fired his elemental Rhotuka spinner, knocking Roodaka unconscious. All of the Rhotuka, however, made contact with the shard, and Teridax was set free. He then used his shadow powers to teleport Roodaka away. Keetongu, recognizing the Toa were worthy of his gift, used his healing powers to restore the Toa Metru to their original state, and the Toa left the island with the remaining Matoran. With the Matoran gone and the Visorak dispersed, Teridax had only one remaining item left to take from Metru Nui, and that was the Vahi. He searched the Great Barrier for it, but instead found an unconscious Vakama. He decided to create an illusion around Vakama to trick him into revealing the Vahi. The illusion contained Vakama as a Matoran, and the Matoran who knew the locations of the Great Disks as Toa. Teridax also disguised himself as Turaga Lhikan, and tricked Vakama into teaming up with a Boggarak that appeared as Nokama. Vakama eventually reached Teridax's base in Po-Metru where Vakama had a vision of Krakua, a future Toa of Sonics. This vision convinced him that the illusion was fake, and when Teridax arrived as Lhikan, he shot a Kanoka Disk at Nokama, ending the vision. Teridax learned that the Mask of Time had been taken by Voporak, who was working for the Dark Hunters. Teridax and Vakama made an alliance to save the Vahi, until it was out of the hands of the Dark Hunters. Trailing "The Shadowed One", the Dark Hunter leader who had come to Metru Nui to investigate the disappearance of Nidhiki and Krekka, they sought to reclaim the Vahi from him. While Vakama entered the Great Temple to do battle with the bodyguard of "The Shadowed One", Sentrakh, Teridax fought Keetongu, who had sensed his presence and came after him to destroy him. The mighty Rahi was unable to defeat Teridax, and would have been killed by him had Vakama's battle not caused an explosion that knocked Teridax away. Teridax soon had other matters to deal with; "The Shadowed One" had arrived with the Vahi and Voporak. The two dictators argued, and Vakama took advantage of the animosity between them to point out Teridax's new appearance to "The Shadowed One". Recognizing parts of Nidhiki and Krekka in Teridax, "The Shadowed One" declared war on the Brotherhood of Makuta in revenge. In the ensuing battle, "The Shadowed One" used his eye beams to sever the wings from Teridax's body. The Brotherhood of Makuta leader disabled Voporak by rendering him unconscious through suffocation, then overpowered "The Shadowed One" and threw him at Voporak, causing him to age rapidly. During the battle, Vakama stole the Vahi, and flew to the ruined Great Furnace using his disk launcher. Teridax opened pursuit, and eventually caught up with the Toa of Fire. Vakama threatened to destroy the Vahi unless Teridax agreed to allow him to leave with the Vahi and not attack the Matoran. If the Vahi was destroyed, all time would end, leaving Teridax no choice but to agree to leave the Matoran alone for a year. The two agreed to the deal, and Teridax teleported Vakama to the Isle of Mata Nui. Teridax, having scanned Vakama's mind during the conflict, traveled to the site Toa Metru's battle with Mavrah, and recovered the Matoran Sphere they had lost. The Matoran inside, Ahkmou, soon awoke, and Teridax fabricated a tale of the lies and deceit of Toa, gaining the Matoran as an ally. Shortly afterward, Teridax left Mata Nui to confront Icarax, who had chosen to rebel against the Brotherhood and take over the Matoran Universe on his own. Teridax let Icarax gain the upper hand, allowing the Makuta attack him continuously for hours. However, once Icarax became too exhausted to continue, Teridax retaliated by first turning Icarax's Manas army against him, and then attacking viciously himself. After the battle, Teridax chose to let Icarax live because he still required his abilities, then returned to Mangaia to await the arrival of the Toa Mata.

Mata Nui
True to his word, Teridax waited one year before he attacked the Matoran. Traveling to the Isle of Mata Nui, he found that the Toa had sacrificed their energy to awaken the Matoran, transforming into Turaga. With the island defenseless, Teridax used Kraata to infect masks, which in turn he used to make the island's Rahi his servants. He used these Rahi to harass the Matoran and keep them in fear and to prevent them from returning to Metru Nui, as Mata Nui could then be awakened. Teridax continued to assault the Matoran for almost a thousand years, until Takua, an Av-Matoran disguised as a Ta-Matoran, found Toa Stones, which brought the Toa Mata to Mata Nui. The Toa Mata learned of Mata Nui's situation, and quickly collected the Great Masks. They used these Kanohi to enter Mangaia, Teridax's lair. The Toa fought both the Makuta's Manas and the Shadow Toa he created until they reached Teridax himself. He disguised himself as a Matoran, the one thing that it was their duty to protect. After a short exchange in which Kopaka saw through his disguise, Teridax transformed into a swirling mass of rusty machine-parts and tentacles. The Toa Mata managed to survive his onslaught and used their combined elemental energies on him. He then collapsed, extremely weakened. In order to distract the Toa and regain his power, Teridax activated a signal to awaken the Bohrok. The Bohrok were eventually defeated and the Toa Mata were exposed to Energized Protodermis and became the Toa Nuva. Special Bohrok called Bohrok-Kal appeared and stole the Toa Nuva's elemental powers. They were soon defeated by the Toa Nuva, but not without difficulties. By the time the Bohrok-Kal were stopped, Teridax had recuperated.

Mask of Light
The Avohkii was soon discovered by Takua. Knowing the threat this posed to him, Teridax unleashed three Rahkshi: a Guurahk, Lerahk, and Panrahk, to find and retrieve the Herald of the Seventh Toa and the Mask of Light. The three Rahkshi destroyed Ta-Koro, though Takua had already left with the Mask of Light. The Rahkshi caught up with them in Ko-Koro, but were frozen in a lake of ice due to Kopaka's intervention. The Makuta then sent an additional three Rahkshi to find the Matoran, a Vorahk, Kurahk, and Turahk. Teridax appeared to Takua in a dark tunnel in Onu-Wahi, demoralizing the Matoran and frightening him into abandoning the quest. However, despite Teridax's best efforts, during the Battle for the Kanohi Avohkii Takua realized he was the Toa of Light, and placed the Mask on his face to transform into Takanuva. Takanuva easily destroyed the Rahkshi, and the Toa Nuva built the Ussanui out of the remains. He used the vehicle to descend into Teridax's lair to confront the Master of Shadows. Teridax mockingly challenged the Toa of Light to a harrowing version of the popular Matoran sport of Kolhii, in which each contestant attempted to hit his opponent with a ball of Energized Protodermis. Takanuva narrowly won the contest, but it was not the end of Teridax. Takanuva attempted to unmask his foe, but he resisted, and they both fell into a pool of Energized Protodermis. What emerged from the pool was a being comprised of both Takanuva and Teridax: Takutanuva. He lifted a massive stone Hau door, revealing a small chamber which led to Metru Nui. As all the Toa Nuva, Turaga, and Matoran hurried in, Takutanuva stopped Hahli and then used a portion of his power to revive Jaller, who had died in the quest for the Toa of Light, from his mask. This weakened Takutanuva, and he was crushed by the gate he was still holding up. Takanuva survived the encounter, but Teridax remained beneath the door, his armor shattered and his essence left to float. The Matoran took this to believe that Teridax was dead, and returned to Metru Nui.

Voya Nui
A Dark Hunter by the name of Hakann soon heard a rumor that Teridax had been killed by a Toa of Light. He took with him five other Dark Hunters of his species: Zaktan, Vezok, Avak, Reidak, and Thok, to Teridax's abandoned base. There they found the remains of the door, and the Piraka, as they called themselves, cleared the door's remains until they found Teridax's shattered armor. With his body exposed, he released his essence into the air. He then planted information into all of the Piraka's minds of the Kanohi Ignika, the Mask of Life, which was hidden on the island of Voya Nui. The Piraka decided to travel to Voya Nui to steal the Mask of Life, and Teridax's essence followed them there. Once the Piraka arrived on Voya Nui, they claimed to be Toa. Even this claim could not help them reach the Mask of Life, however, and the Makuta planted into Zaktan's mind the secret of his essence and the idea to build a crystal vat. Teridax's essence was collected in the vat and transformed into a greenish-black viral substance. The Piraka named this "Antidermis". While in the vat, Teridax was almost helpless, but could still think and plot. His Antidermis was placed in Zamor Spheres, forcing anyone hit by them to do anyone's bidding, much like the effects of Infected Kanohi. Teridax allowed only one person to approach the vat to place Antidermis in the Spheres: Zaktan. Teridax waited inside the vat, until Brutaka and Axonn had a showdown inside the chamber of the vat itself. Axonn smashed the vat near the end of it, releasing Teridax into the air. During this time, the Ignika had fallen into the depths of the Voya Nui bay. The Toa Inika went down "The Cord" to "The Pit" where the Mask of Life had drifted, and the Makuta's essence followed them there. When Matoro used his Iden to unleash his spirit, Teridax took over the Toa's body. He then used his power to plunge the tunnel into complete darkness and stole Hahli's Elda to prevent her from seeing Matoro's spirit outside of his body. However, Hewkii exposed Teridax's trick, and the Inika threatened to destroy Matoro's body rather than let Teridax occupy it, driving him out.

Mahri Nui
Once in "The Pit", Teridax took over the body of "The Pit" Guard Robot Maxilos. While he was there, he was contacted by Gorast, who informed him that they had found a way into Karda Nui. He ordered the most powerful Makuta to occupy it and transform as many Matoran of Light into Shadow Matoran as possible. Disguised as Maxilos, he revealed himself as Teridax only to Matoro, freeing the Toa who had been captured by Hydraxon, and stayed with him as a companion. He deserted the robotic body temporarily when Matoro faced Pridak's army of Takea Sharks using his Tryna, as the Makuta did not want the Barraki to recognize him. He took Matoro down to the Inner Pit, where he stated that he had found something there which would answer some of Matoro's questions. He also discovered the remains of a rogue Toa named Tuyet in "The Pit", who was banished there after abusing a powerful artifact called a Nui Stone. Teridax forced Matoro to use his mask power and reanimate Tuyet so that he could claim what he believed to be Nui Stone fragments embedded in her armor. With the shards accessible, he planned to use the Staff of Artakha to restore the Nui Stone. He used his power of telepathy to tell Icarax to bring him the Staff of Artakha, but the fabled tyrant Karzahni was also in the area with his own goals of universal conquest. Overhearing the discussion about the staff, Karzahni attacked, taking out Tuyet's remains and defeating Matoro easily. Teridax fought back and gained the upper hand, until Karzahni used his Kanohi Olisi. Teridax saw Mata Nui awaken and bring vengeance on those who dared to rebel against him - vengeance terrible enough to make even Teridax scream. Teridax managed to recover from his vision and struck Karzahni. Standing over his downed opponent, he used his power of telepathy to tear through Karzahni's mind. He then finished the fight by using his magnetic energy to send the tyrant flying out of sight. Soon after a dispute between Icarax and the Toa Nuva, Icarax delivered the Staff to Teridax. He began to activate the staff's power, and when Matoro tried to stop him, he was frozen in one of his stasis fields. Before the Makuta could reconstruct the Nui Stone, however, he was stopped by a now mutated Brutaka. During their fight Brutaka grabbed the staff from Teridax and summoned Botar who then took the staff and teleported away, ruining Teridax's plan. Brutaka told Matoro to return to the other Toa and he did, trusting Brutaka over Teridax. Teridax then attacked Brutaka, who easily countered Teridax's attacks. Brutaka convinced Teridax to leave and retrieve the Mask of Life, which was at the time in the hands of Hydraxon. He left, knowing Hydraxon was likely to destroy the Ignika, but not before promising Brutaka that their battle wasn't over. Teridax was next to Matoro after the short conflict between Hahli, Hydraxon and Mantax. Wanting to get rid of Teridax, Matoro suggested to the Toa Mahri that Maxilos would track Hydraxon down. Without a choice, the disguised Makuta headed off in search for the jailer, with Spinax alongside him. After a brief search, Teridax managed to track down "The Pit" Jailer. Hydraxon, thinking that Maxilos was still "The Pit" Robot, asked the guardian to go with him in search of Mantax. When Teridax tried to persuade Hydraxon to stop following Mantax and capture the Toa Mahri and the other Barraki, and failed, Teridax attacked the jailer. Realizing for the first time that Maxilos was no longer a robotic guardian, Hydraxon summoned Spinax to attack Maxilos, only to see the Energy Hound swiped away by the powerful being. Hydraxon, keeping in mind how powerful a Makuta would be, attacked Teridax using daggers, which he stuck directly into Teridax's legs. Ripping the daggers out, Teridax roared at Hydraxon, and the sonic sound blast knocked Hydraxon off his feet. Hydraxon managed to aim his Cordak Blaster at an undersea mountain, causing boulders to rain down on Teridax. By the time Teridax got out of the avalanche, he had already drifted off to the Razor Whale's Teeth. There, with Maxilos' body badly damaged, Barraki Takadox attempted to hypnotize Teridax into killing Mantax. Casting Takadox aside, Teridax was attacked by Matoro, who froze him in a solid block of ice. The sudden decrease of temperature caused cracks to appear on the body, and Teridax's Anitdermis essence began to freeze as well. Later, during a fight against Hydraxon, Jaller's flames melted Maxilos' prison, and Teridax advanced towards the Mask of Life. Before he could reach it, however, Jaller slapped at the mask, and it spiraled upwards into Matoro's hands. To Matoro's surprise, Makuta did not launch any form of attack on Matoro, and simply watched as the two Toa disappeared. Teridax then turned to confront the Barraki, revealing that he was not Maxilos at all and was actually the Makuta who had led to the Barraki's defeat. Enraged, the Barraki attacked Teridax, only to have four of their members defeated. Takadox then attempted to get out of the attack by showing Teridax a Tablet of Transit, but was cast by him into a vision, displaying the Barraki's destiny. Unknown to Teridax, however, the other Barraki were slowly gathering their armies. By the time Teridax stopped displaying the vision, the Barraki had already assembled their armies and revealed to Teridax that they were only pretending to be defeated. They then summoned their troops of over 100,000 underwater Rahi against Teridax. Maxilos' body was greatly damaged after being attacked by the Barraki's armies. Pulling himself up from the fight, Teridax simply let the Barraki go, knowing that his job was only to delay them, and not destroy them. He felt the abrupt change when Mata Nui died, and knowing that it could not be the end, he prayed to himself in his mind that the Toa Mahri would continue their task to revive the Great Spirit so that his plans could succeed. Teridax later left the armor of Maxilos and traveled back to Metru Nui.

Completion
After he was back on Metru Nui, Teridax traveled to the Core Processor, located somewhere beneath the Coliseum, which Teridax got to by slipping through the recently-made cracks in the Coliseum's foundation. He eventually reached his planned destination, which was the former location of the Mata Nui's spirit. Before Mata Nui's spirit could return to this location, Teridax arrived first and took over Mata Nui's body, allowing him to sense that Jaller, Hahli, and Nuparu were in danger on the Isle of Artidax. He spoke telepathically to Jaller, then prodded him awake with a jolt of pain. While waiting for Mata Nui's body to awaken, the Toa Hagah and Miserix arrived in the chamber, looking for him. Seconds later, Helryx and Keetongu came through a portal created accidentally by Vezon's Olmak, and Axonn, and Brutaka then arrived using Brutaka's Olmak. Realizing why they were there, Teridax unleashed a bolt of energy from one of the panels of machinery, shattering Brutaka's Kanohi Olmak, thus preventing the crew from leaving. After a few moments of conversation, he killed Zaktan by shattering his globe and causing him to explode with it. Miserix attempted to destroy the machinery of the room, hoping to kill Teridax. Teridax retaliated by creating a powerful illusion which cloaked Miserix from the others and created a picture of him on the wall, and also made the Makuta himself believe he was only a portrait. Teridax then turned his attention to the Hagah, and mentally altered their minds to only see peace and happiness wherever they go. After the Toa Hagah had departed, Teridax teleported Axonn, Brutaka, and Keetongu to the southernmost edge of the universe. He chose to keep Helryx with him as permanent council, so that he could share with her all of his thoughts and ambitions. Some time later, the Toa Nuva awoke Mata Nui's body from Karda Nui, and Teridax finally claimed dominance over it, and subsequently the entire Matoran Universe. He quickly exercised his newfound powers by assisting the Toa in defeating the remainder of his Brotherhood. During the celebration on Metru Nui, Teridax revealed himself to the Toa, Turaga and Matoran on the Island City, announcing that he had obtained domination over the Universe, and arranging the stars above Metru Nui into the shape of the Kanohi Kraahkan. He also bound Mata Nui's spirit to the Ignika, and ejected it into space, removing their last hope of salvation. Sending a group of Rahkshi after the Toa and Matoran of Metru Nui soon after, he then turned his attention to the Isle of Daxia, destroying it. Afterwards, he sent another troop of Rahkshi to seize the island of Odian and a group of Exo-Toa to retrain the Toa Nuva. He then sent a larger army of Rahkshi to seize Artakha. While contemplating his potential to conquer other worlds, Teridax remembered Mata Nui, trapped in the Mask of Life as it flew through the universe, and considered finding and crushing the former Great Spirit. However, his attention was diverted when he sensed another Makuta from an alternate dimension, and went to deal with the issue. Teridax then called to the Red Star and departed the Aqua Magna moon, intending to travel to Bara Magna and kill Mata Nui once and for all. He became aware of a conflict between Miserix, Artakha, Helryx, Axonn, Brutaka, and Tuyet within the Core Processor, and requested that the group leave the chamber. They refused, and he teleported them, along with two Matoran and Lewa present, out of the Matoran Universe and into space. He arrived on Bara Magna shortly after Mata Nui had possessed a new robot, and confronted his brother. Mata Nui revealed that they were intended to work together to repair Spherus Magna, and not to fight each other. Teridax instead offered Mata Nui the chance to join him on his conquest of the known universe. When Mata Nui refused, Teridax unleashed the destructive energies of his robot body, striking Mata Nui’s robot body. Mata Nui continued to insist that they work together, and Teridax struck him down with his hand. He mockingly called for the Great Beings to reveal themselves, if his destiny was truly to reunite the planet, and told Mata Nui that he should abandon his own efforts. Mata Nui refused to do so, having a strong connection to the inhabitants of the planet. Disgusted by his brother's new sense of caring, Teridax located the population of Agori and Glatorian inside a sheltered mountain cave and tore the mountain away, threatening to drop it on them. Mata Nui became enraged and struck him before he fired a beam of energy that shattered the mountain to dust. During the ensuing confrontation Teridax reminded Mata Nui that his body was host to the Matoran Universe, and that striking him could mean harming the innocent beings inside of him. Futile efforts from the Glatorian attempting to penetrate his armor finally caught his attention, and he unleashed a wave of energy towards the Glatorian resistance and set loose a number of waiting Rahkshi and Skakdi armies onto Bara Magna. After pummeling Mata Nui with lasers, Teridax claimed Bara Magna as his own. Teridax witnessed the formation of the Golden Armor and scattered the pieces with an explosion. After being physically harmed by Mata Nui, he sent squads of Visorak to repair the inside damage. Finally realizing his brother and allies could never be controlled, Teridax angrily summoned a burst of gravitational energy, intending to use it to destroy Bara Magna. Mata Nui desperately managed to deflect the blast towards Bota Magna and Aqua Magna, drawing them back into the planet. Tahu, who had by then recovered the pieces of the Armor, used it to obliterate the Rahkshi, which surprised and weakened Teridax. With a final shove from Mata Nui, Teridax was pushed into the oncoming path of a fragment from Aqua Magna, which struck his head. The damage to his systems ultimately killed him, finally felling the tyrant, and ending his reign.

The Kingdom
In The Kingdom Alternate Universe, Teridax survived the death of the Great Spirit Mata Nui and forced Icarax out of his body to take it as his own. He then began absorbing the armor of each Makuta as they died, gaining mass and the knowledge of each one, and eventually became an unrecognizable colossus. 10,000 years later, he found a way to get through Turaga Takanuva's Light barrier; creating Shadow armor that would last long enough when exposed to the barrier to permit its' wearer to go through unharmed. He planned to bring an army of Rahkshi coated in darkness into "The Kingdom of the Great Spirit" and avenge himself on those who had exiled him. In the tunnels beneath the Kingdom, Teridax encountered Toa Takanuva, Toa Tanma, and Toa Matoro. During the ensuing fight, he used his fragmentation power to kill Tanma, and absorbed Matoro with his Shadow hand. Matoro intentionally allowed himself to be absorbed because he knew that, after a ten-thousand year exile and the failure of his plans, Teridax had no real will left to fight. He was able to overpower Teridax's mind, killing both of them in the process.

Dark Mirror
In the Toa Empire Alternate Universe, Teridax wears an Infected Kanohi Hau due to the fact that the Kraahkan is locked up in the Archives. Takanuva encountered the Makuta in the form of Tuyet while in search of Krahka. He and the two other Makuta there, Krika and Kojol, later agreed to help Takanuva to find Brutaka, provided that the Toa retrieve the Vahi from the Matoran Jaller. Teridax joined in the battle against Tuyet at the Coliseum, but was forced to retreat due to the Toa of Iron and Plasma that had killed Kojol. However, he soon charged up his forces again, and combining with the efforts of Krika, they managed to fell the Matoran and Lewa.

Brothers In Arms
In The Melding Alternate Universe, Teridax and the other Makuta were created by the Great Beings on Spherus Magna to aid the Toa in protecting the villagers and create new life forms. The Makuta here were trained to purge their inner darkness, and they gained Light abilities as a result. Teridax became a devoted force for good and a servant of the Great Beings. When confronted by the Macku of his universe, Teridax agreed to guide Mazeka and Vultraz, who had recently arrived through a dimensional gate, to the Great Beings. As Mazeka pleaded with the Great Beings to help, Teridax revealed that he had used his telepathic powers to read Vultraz's mind, and discovered he was full of Shadow. Vultraz was then forcefully taken away for testing, as Mazeka and the Great Beings were making a deal. Mazeka was given a choice of picking an individual from the alternate Spherus Magna to come back with him, thereby maintaining the balance between universes. The Ko-Matoran picked Teridax, and the Makuta and Mazeka then stepped through a portal and ended up on the Southern Continent. Traveling across the continent, the two came upon a valley of malicious living grass, and the Makuta demonstrated his power over Light to the Ko-Matoran by killing the plants. The two eventually came upon a ridge overlooking a deserted Ba-Matoran village, where they discussed how, had he been in his situation, the alternate Teridax may have been just as ruthless as his counterpart. The Teridax of the main universe then created a maelstrom which blew the pair down to the village. Through the mouths of the dead Visorak scattered around the village, the Makuta spoke to them, saying that a weaker version of himself could never defeat him. The alternate Teridax stated that he was stronger because he resisted the temptations his counterpart could not. As a response, and to end the threat posed by another Makuta, the Teridax of the Matoran Universe teleported three Shadow Takanuva to the village.

The Legend of Mata Nui
Turaga legend said that in the time before time, the dark spirit Makuta grew jealous of his brother Mata Nui and cast him into a deep sleep. Makuta was described as a whirling, screaming beast. It was said that he - or it - could be many things at once. As the Makuta's shadow fell across the land, the ancient values of the Matoran began to be forgotten. The Matoran of Mata Nui began to lose hope and sight of their ideals as guardian Toa failed to appear. When Teridax says that he is the brother of the Great Spirit Mata Nui, this is only in the sense that Teridax worked with him towards a common goal, much in the same way that Toa refer to each other as brother or sister.

Abilities & Traits
Teridax had a very diverse personality, ranging from an arbitrarily fierce enforcer to a cunning mastermind. He was arrogant, proud, and narcissistic, desiring praise and devotion and becoming jealous when others got it; he was, in essence, a sociopath. Teridax had proven to be an excellent strategist, planning for every eventuality, including setbacks. Teridax could also lie easily, and could trick others into helping him. Teridax was considered to be one of the most powerful beings in the Matoran Universe. He had a wide array of powers, all of them being standard to a Makuta. Teridax's primary power was the ability of Shadow. He has been known to create blasts of Shadow and cloak an area in Shadow. In addition to the ability of Shadow, Teridax also had access to the forty-two abilities of the Rahkshi. It should also be noted he knew how to control Protodermis, as demonstrated when he was trying to stop the Toa Metru from carrying the six Matoran Spheres to Mata Nui. Teridax was biomechanical, but, like all Makuta, evolved into a state of pure energy, past any need of a physical body. His armor, as well as allowing him to intimidate his foes, helped to contain Teridax's essence. The armor also allowed him to shape-shift and grow in mass if he absorbed other beings. He accomplished this by launching a massive arm of Shadow from his body to grab the intended target. However, he could not manipulate it like a limb - once it was launched, he could not recall it until it had something in its' grasp. Because it contained his energy, it was dangerous for Teridax to allow his armor to be fractured or broken. Causing the armor to crack resulted in his Antidermis leaking out. As a result of being crushed by a door, Teridax's armor was completely destroyed, and his energy released. While in his Antidermis form, he was only capable of using his various mental powers, such as mind reading, illusion, etc., but not the ones for which he needed a physical body, such as laser vision, disintegration, and so forth. While in this form, Teridax could also possess robots or spiritless, yet still living, bodies. Teridax also had the ability to create Kraata. The repulsive, slug-like creatures were pulled from his essence and obeyed his bidding. By immersing a Kraata in Energized Protodermis, Teridax could also create Rahkshi; then, he would create another Kraata of the same variation to control the Rahkshi. This ability of Teridax's was shared with all the members of the Makuta species; however, as it takes up so much energy, Teridax only used it as a last resort. As a Great Spirit, his powers had been greatly enhanced, allowing him to manipulate all elements inside his body, that is to say, the Matoran Universe. However, he lost access to several of his physical powers, such as shape-shifting.
 * The alternate Makuta is clad in white armor, representing his dedication to the Light. As a result of intense training, this Teridax has shunned his darker nature, and has access to Light powers. Like in the prime universe, the alternate Teridax has access to all forty-two abilities of the Rahkshi, including telepathy.


 * The alternate Teridax is wise and knowledgeable, and understands the gravity of decisions both important and negligible. He realizes that giving into his impulses can easily lead him down the wrong path, and strives to make the right choices. Through his training he, along with the other Makuta, conquered their ancient curse of ambition.



Mask & Tools
One tool Teridax was known to carry was the Staff of Darkness, a giant bladed staff that he sometimes used to channel his powers. The tool could also be used as a Kolhii Stick and was able to hold balls of shadow. He had used a Turaga Staff as well, but only when he was in his Turaga Dume disguise. Teridax wore the Kanohi Kraahkan, the Mask of Shadows, which could sow hatred or fear into others. This mask could change shape when he did, such as when the Toa Mata encountered him wearing an infected Hau. It is known that he can wear other masks as well; however, Teridax considers normal Kanohi to be beneath him and is too arrogant to use them. He attempted to make Kanohi himself in the past. His attempts were found by the Toa Metru in his lair and possibly hint at his own try at making a Mask of Time. He also had slaves of the Brotherhood of Makuta try to make him masks. Teridax stopped wearing the Kraahkan following his battle with Takanuva, allowing Icarax to recover and wear it, although he expressed interest in retrieving it at some point, however it was eventually destroyed.
 * The alternate Teridax bears a golden Kanohi Great Kraahkan, Mask of Shadows. He wears the mask in order to directly confront the looming presence of darkness, and to show that he can overcome it.


 * This alternate Makuta also carries a Warhammer.

Forms
As a shapes-shifter, Teridax had taken many different forms throughout his lifetime. As he was also made of energy, he was capable of possessing living - but spiritless - bodies. Below is a list of his known shapes and bodies:

Quotes
"But I know the Makuta is here now, in these burnt trees, and in the dead soil. All of these things were destroyed by the Makuta, but he never left them. That is how he becomes strong. That is what the Makuta does. He destroys things."

- Kapura, Mata Nui Online Game

"The people of the world are builders. But look into their hearts, and you will find they also have the power to destroy. I am that power. I am destruction. And I WILL destroy you."

- Teridax to the Toa Mata, Mata Nui Online Game

"I am the shape in the shadows. I am the darkness in the heart of Mata Nui. I live in the dread stories told by the Turaga around the village fires. The dark creatures -- the Manas, the Rahi -- are my servants. I am Makuta."

- Teridax, Triumph of the Toa

"You cannot destroy me, for I am nothing."

- Teridax to the Toa Mata, Mata Nui Online Game

"You ... made a ... mistake, Karzahni. You see, I don't get nightmares ... I give them."

- Teridax to Karzahni, Dreams of Destruction

"Sometimes, my brothers, the best way, the only way to win... is by losing."

- Teridax, Into the Darkness

"Your talents are still of some use to me, and so I will not kill you...today. But one day-–perhaps in a year, or 1000 years, or 100,000 years-–I may grow tired of you, Icarax. You may cease to be amusing, with your posturing and your boasting and your lust for battle. And on that day, your armor will be a meal for metal-eating scavengers, and your essence a wisp on the wind."

- Teridax to Icarax, The Mutran Chronicles

"You once told the Toa Mata that you could not be destroyed, because you were nothing. You were wrong-–it is because you are nothing that I can destroy you. You have no heart, you have no spirit, you have no reason to exist-–even your hate is a pale reflection of what once burned in you. You survive out of habit, monster, and habits ... and minds ... can be broken."

- Alternate Matoro, to Alternate Teridax, The Kingdom

"I am the ground you walk on ... the air you breathe. No longer must I fight you to rule a Universe. I AM the Universe!"

- Teridax to the Toa Nuva, Mata Nui Rising

"I have no allies, for I have no equals."

- Teridax to Helryx, Dwellers In Darkness

"A turn to the left instead of the right, a wound received or avoided, rising from slumber an hour too early or too late ... these are the little things lifetimes hinge on, Mazeka. Your Teridax took a step on a path that circumstances allowed me to avoid. If circumstances had been different, who knows?"

- Alternate Teridax, Reign of Shadows
