Underwater Trap

The Underwater Trap is an object that appeared in the BIONICLE series.

Appearance
The Underwater Trap is a makeshift device, which made out of various pieces of the salvaged parts of old weapons. It also have two tubes attached on each sides of the spring-loaded arms.

History
Not much was known of the Underwater Trap's origin, but it was created by the two Matoran, Sarda and Idris during their time in Mahri Nui.

Following Karzahni's defeat in the hands of the Toa Mahri, Toa Lesovikk, Sarda and Idris found the defeated and wounded Karzahni as Sarda had Lesovikk lured him into the trap while he and Idris set up the Underwater Trap. As Lesovikk provoked Karzahni into chasing him into the trap, Sarda and Idris were hiding in the underwater cave along with the Underwater Trap. Soon after Karzahni and Lesovikk headed towards the cave, Lesovikk, Sarda and Idris manages to escape as Karzahni charged towards the trap, which snapped shut around him. The ruler was unable to escape and watched helplessly as Lesovikk prepared to kill him but stopped himself from doing so as the Toa of Air became disgusted of Karzahni's maddened state. Karzahni was then abadoned as the three decide to find the way out towards the surface.

Karzahni was trapped in the Underwater Trap and remained in the ocean until the reformation of Spherus Magna where he was relocated in the planet. He broke out from the trap before he was murdered by the former Dark Hunter, Tyrant using Lesovikk's Air Sword.
