Krekka was a strong, but dumb ape-like dark hunter mercenary hired by Makuta Teridax along with Nidhiki to help him take over the universe and overthrow Mata Nui.
He appeared in the film Bionicle 2: Legends of Metru Nui, alongside Nidhiki. They attacked the Toa several times. On the last occasion, Toa Onewa controlled Krekka to attack Nidhiki, and then sent them flying toward the cloud of darkness created by Makuta, who took the opportunity to absorb both Dark Hunters, thus killing them.
He was voiced by Michael Dobson.
