Rahi Nui

The Rahi Nui is a mutant Rahi created by the Brotherhood of Makuta, it has the head of a Kane-Ra, the forelegs of a Tarakava, the body and hindlegs of a Muaka, the stinger of a Nui-Jaga, and the wings of a Nui-Rama. It was specifically bred to hunt Toa and feed on their Elemental Energy. It originally had the eight basic Kanoka Disk powers, but lost them after the Toa Metru made it grow so big its atoms drifted apart (though the creature was able to pull itself back together eventually). It was more recently defeated again when it got its horns stuck in a wall while fighting the Toa Nuva.
