Location City of the Mask Makers

Harvali is an archaeologist of the Region of Jungle.


Harvali is an Okotan of the Jungle Tribe. She began a career as an archaeologist and became an experienced mountain climber.

Harvali discovered ancient reliefs in a cliff below the City of the Mask Makers picturing the Elemental Creatures and the Temple of Time. Harvali estimated these drawings were made long before the Mask Makers were born, and asked Vizuna, the Protector of Jungle, to climb down so that he could see the reliefs himself. She was determined to build a bridge so that the rest of the islanders could see and study the carvings, but Vizuna tried to discourage her for the idea being too risky. She ignored the Protector of Jungle and built the bridge by herself.

A year before the Toa arrived in the City of the Mask Makers, Harvali went missing and the local villagers informed Vizuna of her disappearance. The Protector investigated the bridge and found the markings of Skull Spiders, but no sign of the archaeologist. He left the bridge intact so that in the slight chance that Harvali had survived, she would have an escape route, but declared as a precaution that no villager should ever come near the road.

Harvali had survived in a nearby cave, but was cornered by a giant snake possessed by a Skull Spider which prevented her escape. She armed herself with a spear and managed to survive until the Protectors arrived, searching for an alternate path to the City of the Mask Makers after Onua destroyed the bridge leading to the city.

The Protectors managed to free the giant snake, and Harvali guided them to the lair of the Lord of the Skull Spiders, which was the only way into the city. The Protectors managed to kill the Lord of the Skull Spiders by bringing down the ceiling on top of him and the rest of the Skull Spiders, and the group arrived at the city just as Ekimu defeated Kulta.

Harvali soon designed a rope bridge, built with the help of the Toa and the Protectors, to allow the citizens of Okoto to return to the city.[RotSS]

Abilities and Traits

Harvali is a skilled mountain climber and was known to design and build rope bridges in Okoto.[RotSS]

She carried a spear while living in the cave.[RotSS]

Dekar was a Po-Matoran Aqua Hunter and former resident of Mahri Nui. He has been transformed into a duplicate of Hydraxon by the Kanohi Ignika.



Dekar preparing to destroy the Ignika

Dekar was initially from the same island as Sarda and Idris. After Lesovikk and his team failed to defeat a tribe of wandering Zyglak, the local Turaga went mad and sent all of the resident Matoran to Karzahni, including Dekar. There, he was rebuilt into a twisted, weaker form by Karzahni himself and given a pair of Electro-Blades to compensate for his new body. Along with several other rebuilt Matoran, he was relocated to the Southern Continent. During the Great Cataclysm, Dekar was on the land mass that broke off and became Voya Nui.

Several hundred years later, a village that had been built on Voya Nui broke off into the sea, taking Dekar and many other Matoran along with it. The Matoran were briefly exposed to the mutagen in the water, being partially restored to their former forms. The village landed in a field of Airweed, and was surrounded by an air bubble, protecting the Matoran from mutating further into water breathers. They named the village Mahri Nui.

After the Kanohi Ignika fell into the sea, Dekar was in Mahri Nui when Kyrehx was attacked by the growing plants around her. He saved her, and then both Matoran hid in a nearby building. There, Kyrehx gave Dekar the mask she had found outside the village, not knowing it was the Mask of Life. Dekar tried to take it to the Matoran Council, but on his way, he was attacked by a Venom Eel. He soon discovered that anything he tried to kill instantly recovered from its wounds. Dekar decided that the mask needed to be destroyed because he felt it was too powerful. When he attempted to do so, the mask retaliated, creating a giant Venom Eel. After recovering, the Kanohi "spoke" to him, revealing its history and vital purpose. Four of the Barraki and Brutaka attempted to persuade him to hand over the mask, but Dekar refused to surrender it.

Dekar's transformation into Hydraxon

The warlords then attacked the Matoran, causing him to drop the mask. Despite Dekar's protests, Pridak stole the mask and promised the fall of the Great Spirit. As he did so, the mask emitted a blinding flash of light, knocking the present Barraki and the Po-Matoran unconscious. Dekar came to before his captors and left the cave, leaving the mask behind with Pridak. His air bubble thinning, he desperately swam towards Mahri Nui. As he did so, the Mask of Life sensed his weakening life energy and transformed him into Hydraxon, the late jailer of the Pit. With Dekar's mind and memories completely buried under Hydraxon's, the newly reborn Hydraxon continued his journey. Believing everyone else to be Pit escapees, Hydraxon recruited one of the Maxilos robots and embarked on a quest to capture everyone in the open ocean.


Upon arriving at Mahri Nui, Hydraxon spotted and captured Toa Mahri Matoro. After incarcerating the Toa and throwing him in a jail cell, Hydraxon brought Maxilos and Spinax to guard it. He then left the cell, to continue his mission. Hydraxon later spied on a Barraki meeting, noting their strengths and weaknesses, and listing the types of weapons he would need to capture them. While searching for more escaped prisoners, he spotted Nocturn, and attacked the escapee. Hydraxon was able to defeat Nocturn, and acquired the Mask of Life, which Nocturn had been keeping. Remembering a faint memory from Dekar, he attempted to blast the mask with his Cordak Blaster, believing it too dangerous to be in the Pit. Toa Hahli redirected the Cordak mini-rocket with a riptide and engaged him in combat.

Hahli attacking Hydraxon

Mantax managed to acquire the Ignika in the midst of the fight. Hahli and Hydraxon attempted to attack the warlord, but were drained of energy by Mantax's curse, and sank to the bottom of the ocean. Mantax instructed them to tell the other Barraki to meet him at the Razor Whale's Teeth.

When Mantax had gained enough distance, both Hydraxon and Hahli regained their strength. Hydraxon immediately looked for Nocturn, though the inmate had since fled. The jailor departed in search of Mantax.

Hydraxon traveling along the seafloor

Hydraxon later met with a Maxilos in an undersea mountain overlooking the Barraki's meeting. Maxilos attempted to persuade Hydraxon to chase after other escaped prisoners instead. When Hydraxon refused to do so, Maxilos revealed that the armor was being possessed by Makuta Teridax. Hydraxon summoned Spinax to attack Teridax using an ancient dialect of Matoran. When Spinax was defeated, Hydraxon, knowing the amount of power a Makuta may hold, attempted to paralyze the robotic body with well placed daggers. Maxilos/Teridax unleashed a power scream, knocking Hydraxon down. Refusing to be defeated, Hydraxon aimed his Cordak Blaster at the undersea mountain and fired, burying Maxilos/Teridax in a pile of rubble.

Hydraxon then attempted to retrieve the Ignika from Jaller, who had obtained it, but was suddenly attacked by Spinax. After Hydraxon pushed the beast away, Maxilos knocked Hydraxon unconscious.

Later, Hydraxon encountered the Toa Mahri. When he demanded the mask, Matoro offered it and the attached duty to the jailer. Listening to the Toa Mahri's experiences, he eventually agreed to let them go with the Ignika.

Hydraxon finds the destroyed Maxilos.

After the battle, and the revival of Mata Nui, Hydraxon came across the damaged body of Maxilos. He retrieved the body, now freed from Teridax's control, and took it away in the hopes of repairing it, though he eventually gave up the task. Hydraxon then began attempting to recapture the escaped prisoners.

Hydraxon capturing Pridak

While hunting down prisoners, Hydraxon was confronted by Pridak and an army of Takea sharks. The Barraki leader called him a fake, and Hydraxon admitted that others have told him the same. After defeating the Takea and combatting the Barraki, Hydraxon allowed Pridak to tell his story. Pridak explained to the jailer how a Matoran named Dekar had gone missing around the time of Hydraxon's reappearance, and that the Ignika had made a new Hydraxon out of the Matoran, attempting to demoralize him. Hydraxon insisted on his identity and defeated Pridak, jailing the Barraki.

As he and Spinax continued their task to capture the Pit escapees, he was met with assistance from Lesovikk and Sarda. Initially Hydraxon refused help from them because he thought that the Toa and his Matoran companion were escapee prisoners. However, after realizing they were not, he relented and allied with the duo. Since then, they managed to capture several of the former prisoners, including four of the Barraki and Nocturn. Shortly afterwards, he received a message from Toa Helryx, ordering him to draft the Barraki in the Order's war against the Brotherhood of Makuta. He showed this message to Lesovikk, alerting the Toa to the Order's existence, and released the Barraki. He then began assisting the Order of Mata Nui in their war efforts.[1]

Although the Order won the war, Teridax still managed to usurp control of the Matoran Universe. When Teridax was finally defeated by Mata Nui, Hydraxon was forced to leave the failing universe. Arriving on Spherus Magna, he became amphibious as a result of an energy wave released from the Ignika.[2]

Abilities and Traits


Dekar was a skilled Aqua Hunter. He liked solitude and enjoyed hunting. He was brave, but practical enough to flee if he was losing a fight. He always wanted what was best for Mahri Nui, to the point of attempting to destroy the Ignika.

Hydraxon possesses the same set of abilities as the original, including the combat skills and mental shielding, in addition to the sensitive hearing. He also exhibits the same personality, with a single-minded dedication to the justice of his profession. The Ignika gave Dekar the original Hydraxon's memories, and in turn repressed the memories of his time as a Matoran. While the section of Hydraxon's mind that holds all memories as an Order of Mata Nui member is shielded, the section of his mind that holds his memories as a Matoran is not, and is accessible to mind-readers. Despite faint recollections of his time as a Matoran, Hydraxon is oblivious to his origins; even when presented with evidence of his true past, he refuses to acknowledge its legitimacy, still devoting himself to the job assigned.

To allow him to function underwater, the Ignika gave Hydraxon the ability to only breathe water, and made him immune to the effects of the Pit Mutagen. He was later granted the ability to breathe air by Mata Nui with the use of the Ignika, and has become amphibious.

Mask and Tools

Dekar was equipped with two Electro-Blades, capable of firing a stunning shock. He also wielded an Air Launcher, used to fire spheres of air at water creatures, filling their lungs with air, toxic to them. He also wielded a spear when hunting. He lost these tools when he was transformed into Hydraxon by the Ignika.

Hydraxon carries the same weapons and armor as the original: a Cordak Blaster, Wrist Blades, as well as Exploding Boomerangs. He also bears two Back Blades which he can launch telekinetically.

Hydraxon in Command Toa Hewkii
  • This Hydraxon was technically never inducted as a member of the Order of Mata Nui. However, as he believes he is the original Hydraxon and retains all of his memories, and the Order is unaware of the original's death, he serves as a member anyway.
  • Greg Farshtey indicated that had the original Bionicle storyline continued, Hydraxon might have ended up becoming a bounty hunter of sorts. Meanwhile, the Spherus Magna equivalent of the Pit may have been overseen by Glatorian and the Maxilos robots.[3]
