The lone toa of Teru Nui. When the wretched Gahnrahk were released from an underground prison during an archaeological dig, he could not defend the island. Now most of the island is infested with Gahnrahk and the only thing that stands in their way is within the prison in which they were once trapped. Caru's quest is to travel to the prison and hopefully save his home.
About this creation
His Mask of Vision allows him to see in infrared, night-vision, x-ray, and visible light(normal) mode.
His saw is a very powerful, but heavy, weapon. The fact that he can hold it with one hand shows that he is very strong.
