Pronunciation TREN KHROM[1]

Tren Krom was an ancient, fully organic entity created by the Great Beings, older than Artakha, Karzahni, and the Great Spirit Mata Nui. He was an immensely powerful being, but regarded as simply a myth by many.


Tren Krom was initially created by the Great Beings and placed in Karda Nui to temporarily run the Matoran Universe while they finished their work. Tren Krom saw himself as having birthed a world of order, although he was also responsible for monstrous creations that could later be found on the Tren Krom Peninsula.[2][3] Once Mata Nui was created, Tren Krom was no longer needed, and was approached by an Av-Matoran Toa Canister builder who informed him that his job was complete. Afterwards, Tren Krom was removed from the universe core and sealed away by the Great Beings, who permanently fused him to an island.[2]

The Brotherhood of Makuta once wished to seek out Tren Krom to ensure he was not a threat to them. The Makuta Mutran was chosen to go to his island and investigate. When he arrived, Mutran was confronted by Tren Krom, who then merged their minds to search through Mutran's thoughts. As a result, Mutran learned not only what Tren Krom truly is, but how the universe works, and even why it does. Afterwards, he fell unconscious, and when he awoke he realized he had the key to aiding Teridax in overthrowing the Great Spirit.[4]

When Order of Mata Nui member Brutaka and his team arrived on the island to retrieve a hidden weapons cache, they were attacked by Tren Krom. He attacked out of loneliness and a desire to know what had happened to his universe after his exile, manipulating the stone of the island to suppress the group before pulling Brutaka into the cave with a tentacle.[5] Tren Krom interrogated Brutaka and attempted to probe his mind, but Brutaka's mental training prevented him from doing so. He then informed Brutaka and his team, who had followed Brutaka into the cave, of his origin and what his purpose was. Lariska began protesting their imprisonment, and was then grabbed by Tren Krom, who probed her mind and learned all of what had happened to the universe. Upon being told of the fate of the universe should Teridax's Plan succeed, he instilled horrible visions into their minds.[2]

Meanwhile, Carapar attempted to sneak up on Tren Krom and kill him. However, a third eye grew on Tren Krom, and shot out an energy beam that completely disintegrated Carapar. He then ordered them to leave, claiming that the fate of the universe was what they deserve and far worse than anything he could do to them.[2]

Teridax's Reign

Later, after Makuta Teridax had successfully taken over the Matoran Universe, Toa Nuva Lewa was teleported to Tren Krom's island by Artakha to persuade Tren Krom to fight against the Makuta.[6] Tren Krom informed Lewa that there was a way to free him from his prison so that he could help, but at a great cost to the Toa of Air. Lewa replied that he was willing to risk anything, and Tren Krom transferred his consciousness into the Toa's body, and placed Lewa's into his gelatinous form. Tren Krom departed the cave, intending to remove Teridax from power in accordance with his bargain.[7] Despite his previous anger against the Great Beings, he felt no extreme animosity toward them, and instead felt obligated to save the universe over which he had once presided. Realizing that he could not access Lewa's Air abilities, Tren Krom used his telepathy to contact Artakha. Tren Krom convinced the ancient being to transport him to Metru Nui, where he could carry out his plan.

After arriving in the Archives, Tren Krom was approached by Hafu, Kapura, and Toa Tuyet. Tren Krom quickly scanned their minds, and discovered Tuyet's past actions and current intentions. Tuyet deduced that he was not the real Lewa from the mental probe, although Tren Krom adopted the treespeak pattern of speech to fool the Matoran. The group, after emerging onto the surface, encountered Pouks and Bomonga. The Matoran explained how they had been acting strangely, and after he read their minds, Tren Krom figured out what Teridax had done to them and broke the illusion around them and the other Toa Hagah. Tren Krom then instructed the group to head to the Coliseum, where he intended to send a message to Mata Nui.[8]

When the group arrived in the chamber underneath the Coliseum they encountered Toa Helryx. A portrait of Miserix caught the attention of Tren Krom, and he used his power to free the Makuta from the illusion he had been placed in. He then located a piece of machinery, and began utilizing it to send his message, which was received by the Kanohi Ignika on Bara Magna.[9] After he was done, he was drawn into a conflict, siding with those who did not want to destroy the Matoran Universe. During the fight, Tren Krom fought with Miserix and was slammed to the ground. He retaliated with a vicious mental attack, only to be thrown into a wall.[10] The fighting was interrupted by the sudden arrival of Artakha, who bid Tren Krom leave. Tren Krom attempted to exit the chamber, but was stopped by Artakha, who demanded that he return the body. Tren Krom tried to persuade Artakha to let him keep it, but Artakha told him to have faith in Mata Nui, and restored Tren Krom and Lewa to their original bodies.[11]

Spherus Magna

After Teridax was killed and the Matoran Universe heavily damaged, Tren Krom was released from his island by Velika, a Great Being disguised as a Po-Matoran.[12]

Tren Krom was later murdered by Velika, sending out a telepathic scream with an image of the Red Star that was heard by Kopaka, Pohatu, and Gaardus. They soon found his remains scattered over a forest on Spherus Magna.[13]

Abilities and Traits

Tren Krom was said to possess great power, nearing that of Mata Nui. He had extensive telepathic abilities, allowing him to read beings' thoughts, and affect their mental state. While being mentally searched, the subject in turn could have access to Tren Krom's mind, though the connection usually had adverse effects on the target.[4] Tren Krom could create an extra eye and emit a beam from this eye which could dissolve a target into dust.[2] Tren Krom also possessed the ability to swap minds with another being, but only if the target gave consent.[7]

Tren Krom was originally proud of helping create a universe built on order, and longed to return to power after his imprisonment. However, after learning 100,000 years later how chaotic it had become, he lost faith in its value.[2] Nonetheless, he felt obligated to help free it from Teridax later on.[8]

Due to his extensive knowledge of the fundamental workings of the Matoran Universe, Tren Krom had the ability to manipulate certain aspects of his environment, such as the rock of which his island was composed.[5]

Tren Krom was horrifying and despicable in appearance, and primal in nature. He was fully organic and his scarlet body was covered with tentacles coated with sharp hooks. His eyes were simply holes inlaid into his gelatinous skull. His appearance was so terrible that it was known to drive lesser beings insane. Even Order of Mata Nui member Brutaka had to struggle to hold on to his sanity after seeing Tren Krom.[2]

In Lewa's body, Tren Krom did not have access to many of his abilities that were based on his physical form, but he retained his immense mental powers. He could use Lewa's Miru Nuva, and swap it with Kanohi Nuva from the Le-Suva, but the body swap did not grant him Lewa's elemental air power.[8]


"Tren Krom is no myth. He is older than the stars themselves, born in a time when there was no Mata Nui, no Makuta, only never-ending darkness that encompassed all. He walked through a universe in the throes of its birth, and even the shadows feared him."
— Makuta Mutran, The Mutran Chronicles

"Rather than crush me in his grasp, Tren Krom explored my consciousness, like an Archives mole rooting about for a meal. It was amazing... it was horrifying... it was a view into a mind as far beyond mine as mine is beyond a fireflyer's... and it was feeling my mind turn into a nest of serpents, hissing and slithering and trailing slime."
— Makuta Mutran, The Mutran Chronicles

"You think me an alien ... an 'other' ... But I am of the substance of this universe, and I walked here long before you or even Mata Nui himself."
— Tren Krom to Brutaka's group, Federation of Fear

"I helped to birth a world of order. But from what I have seen in the female's mind ... you have turned it into a universe of madness and fear. It is not worth saving. But it is the universe you and your kind deserve. Take yourselves from my prison ... take your memories and plans with you ... for the horrors already in your minds are worse than any I could visit upon you. I condemn you to your fate — life in the universe you and your kind have made."
— Tren Krom to Brutaka's group, Federation of Fear

"Faith, yes... a drop of water in place of an ocean."
— Tren Krom to Artakha, Reign of Shadows
