Zivon

The Zivon was one of the villains that appeared in the 2005 storyline of the BIONICLE series. It is a gigantic, scorpion-like Rahi that resides in the Field of Shadows and was an ally to the Visorak, though they hate it due of its penchant of eating them.

History
The Zivon was once created by the Brotherhood of Makuta before the main event of the storyline.

During the climatic battle in the Toa Tower, Sidorak, the ruler of the Visorak ordered the four Kahgarak to unleash the Zivon to destroy the Toa Hordika and the Rahaga. The four Kahgarak then used their Rhotuka spinners to open the portal of the Field of Shadows as the Zivon exited from the portal and wreck havoc on the ruined city of Metru Nui to destroy the heroes. The Toa Hordika try to attack the Zivon with their spinners but the monster's hide deflect the spinners and the Zivon then attacked the Toa with its tail, though the Toa manage to dodge its attack. When the Zivon then charge towards the Toa, it suddenly attacked by both the Tahtorak and Krahka, the shapeshifting Rahi.
