Hydraxon

Hydraxon was assigned to be the jailer of The Pit, until he was badly injured by an earthquake and Takadox killed him - "though there are unconfirmed reports he is up and walking around again." It's also interesting that he doesn't know that he had been dead.

Hydraxon is a weapons master, and is equipped with thick armor, explosive boomerangs, wrist knives, and a six-barreled cannon called a Cordak Blaster. He is also amphibious, allowing him to breathe in the now-flooded Pit. He will, in theory, aid the Toa Mahri in their attempt to defeat the Barraki that escaped from The Pit, but has been described as giving the Toa Mahri nothing but trouble. Hydraxon believes everybody in the Pit is a prisioner, that is why he also plans to trap the Toa Mahri. Also, he wants to destroy the Ignika, thinking it is too dangerous. He will fight Nocturn and Makuta.
