Large in appearance but very lightly built, arachnirgaton can scurry across the sand of the arid climates he lives in very quickly and fire a heat beam from his laser tipped tail to fry his prey alive. The beam appears a pulsating blue ray of electricity, it can also select things to capture by using the laser tip as a magnet, the laser weapon is lethally accurate at long distance, arachnirgaton using vibrations in the ground to locate his prey from far away, once located the profile of the bionicle becomes visible in the arachnirgatonís brain determining if it is potential prey for his enormous apatite or something to be left alone. If prey the Arachnirgaton takes off toward its target at speeds of 200mph as a blur in the desertís blowing sand, once with in 3 miles of its target its in the heat beamís reach, for either being captured by the magnetic technique then killed by heat beam, or killed then obtained. Arachnirgaton keeps his distances from civilization, or things that just wouldnít be suitable prey, but if provoked, it wont speed off at its blurring speeds or hesitate to incinerate its attacker with its heat beam. It can grip its prey it has toothy clappers on the ends of 2 arms located beneath its head, If prey is not cooperative witch should be expected the toothy clampers inject neurotoxins into the struggling food to shut down the components of the bionicle and allow for no further difficulties. The Arachnirgaton can burrow deep beneath ground to escape the scorching heat of the desert witch doesnít seem to penetrate his armor plated skin but does slow Arachnirgaton down a bit leading him to become a more nocturnal hunter besides caves he just hunts hidden in the darkness of the night.
