Zivon

History
The Zivon lives in the Zone of Darkness, which can be accessed only by the power of the elite Visorak Kahgarak's Rhotuka. When called forth, the Zivon is a fearsome insectoid monster, towering over 30 feet. Even the hordes would not prefer to see it, for he considers smaller Visorak as a delicacy, and eats them to celebrate for a victory in battle. Zivon's mandibles, crablike claws, a stinger like one of a Nui-Jaga, a hard shell that is good for protecting itself, and massive strength make him a destructive foe. It is also capable of shooting webs from each of its six legs to tangle up an enemy. The Zivon's various Rhotuka can temporarily blind, mute, deafen, and take away the sense of touch from a foe. Zivon can spit venom, but, its stinger doesn't carry venom.

Description
The Zivon was seen on Metru Nui because of the orders from Sidorak. It fought the Krahka, a shapeshifting rahi who was riding on a Tahtorak. They were all in the Zone of Darkness due to the power of Visorak Kahgarak's Rhotuka. The Tahtorak was teleported to Metru Nui by the mask power of Brutaka (an Order of Mata Nui member). In BIONICLE Legends 5: Inferno the Krahka and Tahtorak escaped the Zone of Darkness without the Zivon. It is unknown if Tahtorak killed the Zivon or left it there.
