Doubletone is a two-toned Nighlok who is armed with a bamboo-like spear. Doubletone is based on the Samurai Sentai Shinkenger Warrior-Monster Namiayashi. Laid back and disturbing in personality, Doubletone is sent by Octoroo to increase the River by doing what he loves best, making others cry. Appearing in the mortal realm before a boy named Ryan, he accomplish his goal by tricking the boy with a false promise of seeing his father again. His attack is the Tiger Tidal Wave creating a tiger from the right half of his body and a Sanzu River wave from his left to take out two opponents. He is destroyed by Kevin and Mia, and then destroyed by the Samurai Megazord. He is voiced by Gerald Urquhart.
