Motrokh was a Toa of Water and a Toa of Ice which were fused together. He was with Vorahk-Kah when the Fellowship of Kakamu was formed. He was a member and accompanied Vorahk-Kah and Muta when they teleported onto Darkmount. When the city-ship took off, Motrokh, along with the rest of the Fellowship, were sent into interdimensional space.
