Mantax

Mantax resented Pridak for leading him into disaster - first by being banished to The Pit, and again when Mahri Nui crushed the Barraki fortress. However, he was wary of Carapar, as he has lost when the two have fought in the past.

It has been confirmed that Mantax was in fact looking for a contract stating that one Barraki betrayed the League of Six Kingdoms to the Brotherhood of Makuta.

BIONICLE.com Description
"Dweller in darkness ... the most secretive and mysterious of the Barraki. Spends most of his time buried in the sea floor, with only his eyes and head spikes visible, waiting for prey to swim by. When he's not there, he is down in the flooded remains of the original Pit, for reasons unknown. Traditionally keeps silent and in the shadows, preferring not to share information with the other Barraki unless he has to (knowledge is power, after all). Commands an army of Rays."

Biography
Mantax was one of the six leaders of the League of Six Kingdoms. He was secretive by nature, and no one except his most trusted servants knew even the least bit about him. He led many attacks with his army, all of them successful. He and the other members of the League, along with their armies, led an attack on the Great SpiritMata Nui, but were stopped by the Brotherhood of Makuta and were about to be executed when Botar came and transported them to The Pitjail. Mantax and the other Barraki spent a long time there, until the Great Cactylysm, which shattered the jail, allowing him and the other Barraki to escape. They then roamed around the pit seperatley, though still working together. Mantax formed an army of rays. Their opportunity for revenge came when the Ignika floated down to Mahri Nui. Mantax did not know about this until later, when he was taken by Kalmah to try and stop Dekar, who had the Mask Of Life. They discovered Dekar in a cave, and Kalmah went in close while Mantax waited behind. Then the Ignika created a huge Venom Eel to stop Dekar from destroying it, and it slammed in to Kalmah the force knocking him out. Mantax reported to Pridak what happened, and they both went there to investigate. The other Barraki were there too, as well as Brutaka, but he was taken away by a Giant Squid. Mantax and the others went in and got the mask from Dekar, setting off a bright light that enveloped all of Mahri Nui. Later, when everything was settled, Mantax continued his daily work of looking for the Betrayal Contract that told which Barraki betrayed them to the Brotherhood of Makuta. However, Takadox and Kalmah found out and went to see more, but all three Barraki were found by a group of Zyglak. Luckily, Takadox tricked them and they all got away in time for the arrival of the Toa Mahri. Once they took the Toa Mahri away, they put them in a confined cell, but they all got out. The Barraki came up with a way to solve this problem-to split up and find them. Mantax found Toa Mahri Hahli, and defeated her using stealth and his paralyzing head spikes. Later, Hahli escaped, and fought Mantax again, but this time managing to trick him into thinking that the other Barraki were allying and going against him. This caused Mantax to promote Hahli to his general. Later, Mantax and Hahli went to stop Hydraxon from destroying the Ignika. What fallowed was a complex battle that left the mask in the claws of Mantax, giving him the power to take away energy from others close to him and give it all to him. He stopped Hahli and Hydraxon by using this power, and told them to get the other Barraki ready for a meeting. He then left and got ready, bringing the Mask Of Life and the Betrayal Contract with him. At the meeting, he told the Barraki about both the Betrayal Contract and the Ignika, and was about to give them a list of demands when an avalanche hit, causing Mantax to dive for cover, only to be stopped by Takadox in the chaos, who announced that he was the betrayer, and that Mantax was about to die. However, Toa Jaller and Toa Matoro arrived and stopped Takadox from killing Mantax. However, this gave Mantax a chance for revenge, and he jabbed his head spikes into the blue Barraki's abdomen, not killing him, but severly wounding him. But with Takadox out of the way, it was easier for the two Toa Mahri to knock him out. When Mantax, woke up, the Barraki had gathered together for a final attack on the Toa Mahri, but Maxilos/Makuta got in the way, easily defeating the six of them. But their armies had gathered by now, and destroyed Maxilos, with the Makuta of Metru Nui's fate being unknown. Then, the six Barraki headed for the Toa Mahri. They found them, and commanded their armies to attack with as much force as possible. However, the Toa Mahri were transported away to Metru Nui by the Ignika before the Barraki's armies could destroy them. In frustration, they all turned on each other.The outcome of this situation is currently unknown.

Powers and Tools
Mantax's natural weapons included a pincer, head spikes with paralyzing venom, a tentacle on the back of his head that conducts lightning;he also had a Squid Launcher. He is the best Barraki at ambushing and hiding, and this can be used to his advantage. In Bionicle Legends 8:Downfall, he touches the mask of life and gains the power to drain energy from others and give them to him. However, he had to be holding on to the mask of life to do this. This power was lost when the mask of life was taken away from him.

Army
Mantax's army included a large number of organic undersea rays. They were mentioned near the end of BIONICLE Legends #7: Prisoners of the Pit, and appeared briefly in BIONICLE Legends 8: Downfall.
