Hydraxon

"Who I am is my business. Staying out of my way is yours." -Hydraxon

Originally ,before being assigned to be jailer of the pit he trained the Toa Mata in the art of combat on Daxia. Hydraxon was assigned to be the jailer of The Pit, until he was badly injured by an earthquake, caused by the Great Cataclysm, and Takadox killed him. Before he became the jailer, he was training combat skills for the Toa Mata.

Centuries later, the Mask of Life drifted down into the Pit where it eventually wound up in the hands of a Po-Matoran named Dekar. Seeing some of the dangerous prisoners of the Pit (the Barraki and Brutaka), the Mask of Life, needing a guardian, used its power to transform Dekar into a reincarnation of the late jailer. This "Hydraxon II" fully believes that he is the original, but Dekar's memories are still buried deep within him. While this Hydraxon believes that he is a member of the Order of Mata Nui, only the original is considered to actually have had Order membership.

After being "revived", Hydraxon set out to re-capture all of the escaped prisoners. Because of this, he though everyone in the Pit was a prisoner, and so captured Toa Matoro. After inprisoning him under the watch of Maxilos (who, unknown to Hydraxon, was possessed by the evil Makuta) and Spinax, he departed to round up the other prisoners.

Soon after, he fought Nocturn (who was on his way to find Ehlek, and ask him about his new "death touch", granted to him by the Mask of Life). After defeating him, Hydraxon realized the Mask of Life was cracked and on the way to self-destruction. Deciding the mask was too dangerous to be left in the Pit (and that the mask was damaged anyway), Hydraxon took aim with his Cordak Blaster and fired. Toa Hahli redirected the Cordak mini-rocket with a riptide and began a fight with him. Their fight concluded when Mantax came into possesion of the Ignika, and both Hahli and Hydraxon went to fight the warlord, but Hydraxon sank to the bottom after coming within 50 yards of the Barraki (As Hahli) due to the Mask of Life´s curse over Mantax. Mantax then told them to tell the other Barraki to meet him at the Razor Whale's Teeth, Hydraxon responded that he makes no deals with runners, but Mantax got away with his army of rays.

When Mantax was far enough, both Hydraxon and Hahli regained their strength, Hydraxon immediately looked for Nocturn; only to discover that he had escaped, again. He then glared at Hahli and Hydraxon grumbled at her about interfering, and after Hahli´s in vain try of finding out who Hydraxon was, Hydraxon left the scene for Mantax.

Hydraxon later met with Maxilos in an undersea mountain overlooking the Barraki´s meeting place. During this time, Maxilos attempted to presuade Hydraxon to chase after the remaining five Barraki and six Toa Mahri instead. When Hydraxon refused to do so, Maxilos revealed that the armor was being possessed by the Makuta. After the brief shock of realization, Hydraxon summoned Spinax, who attacked the Makuta. When Spinax was defeated, Hydraxon, knowing the amount of power a Makuta may hold, attacked first by digging wrist blades into Maxilos' legs. In response, however, Maxilos unleashed a power scream, which knocked Hydraxon down. Hydraxon, refusing to be defeated, aimed his Cordak Blaster at the undersea mountain and fired, burrying Maxilos/Makuta in a pile of rubble.

Hydraxon then proceeded to Jaller, who had retrieved the mask. Unluckily, Hydraxon was suddenly attacked by Spinax. After pushing the beast off him, Maxilos came forwards (Now freed from the rubble) and knocked Hydraxon unconscious.

Later, Hydraxon encountered the Toa Mahri. When he demanded for the mask, Matoro simply stated that if Hydraxon wants the mask, then he can have it and save the universe with it, instead of himself. Hydraxon listened to the words, and decided that something was indeed fundamentally wrong with the universe. He agreed to let the Toa Mahri go with the Ignika, as long as they keep out of his way in the future. As he departed, Toa Mahri Hahli stated that while Hydraxon was attempting to recapture the lost prisoners, he is actually the one who is lost.

After the battle and the revival of Mata Nui, Hydraxon came across the damaged body of Maxilos. He retrieved the body, now freed from Makuta's control, and took it away in order to repair it. Unfortunately, it was beyond repair. Hydraxon is now attempting to recapture the escaped with the truth that he was actually a Po-Matoran named Dekar still hidden from him.
