Krekka

Krekka's past is very mysterious. He seved as a gaurd for Sidorak's speceies, but was banished due to unknown reasons. He later worked for the Brotherhood of Makuta, which may have explained why he came to join the Dark Hunters. Krekka, in the known storyline, was a brutish and dumb accomplice to Nidhiki, and helped his friend put great fear into Ahkmou, a helpless Po-Matoran. Their plan (or, rather, Nidhiki's plan) was to force Ahkmou to give them the Great Disks, which in turn they would hand over to Makuta, who was under the guise of Turaga Dume. However, the Toa Metru retrieved the Great Disks first and defeated the Morbuzahk. Meanwhile, they also imprisoned Lhikan.

Once Makuta's plant was destroyed, he told Krekka to accompany Nidhiki to capture the Toa and put them into the cell Lhikan was in. They went around Metru Nui, trying to capture them, and eventually they succeeded partially, catching Nuju, Onewa, and Whenua. They then continued to search for the other three. They went to Po Metru to look for them. Unknowingly, Krekka encountered "Nidhiki". But he was really Matau. After the other 3 Toa found the rest and Lhikan, they went to the Coliseum to hunt for them more. They found them, and Krekka fell victym to Onewa's mask power. He attacked Nidhiki and they both fell into the Makuta, killing him instantly.
