The Rahkshi-Headed Serpent was a twenty-foot-long horned serpentine Rahi that could fire electrical energy from its horns and change color to mimic its surroundings.
This creature attacked Toa Matau during the Toa Metru's journey back to Metru Nui to rescue the Matoran. Later, the Karzahni plant killed it as a gift whilst the serpent was attempting to stalk and kill the aforementioned team of Toa.
