Try and grab a Kavinika off its perch and you will be lucky not to lose one or both hands. Even after the Visorak are dealt with, we will still have to find some way of penning up the Kavinika and finding out how their population is growing. Otherwise, Metru Nui will rapidly be overrun.
Kavinika were wolf-like, bipedal Rahi once used by Ga-Matoran scientists to guard certain places, low - priority facilities and items. Unfortunately, they were overly aggressive and started to fight with each other, Rahi and Ussal crabs. The Kavinika then threatened their Matoran masters. The Ga-Matoran tried to drive the Kavinika out of Ga-Metru, but they had little success. Their population exploded for some unknown reason.
