Rahkshi-Headed Serpent

The Rahkshi-Headed Serpent was a twenty foot long horned snake 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 Karzahni killed it when it was trying to sneak up on them as a gift.
