Bowzock's best graffiti artist, he was hired to use Inventor Grotch's fattening spray to make objects explode, after becoming too fat. Though told to stay put while Grotch gets him Imo-youkan, Nerenko goes on a spraying rampage after seeing graffiti that brings his style to shame. He nearly kills four of the Carrangers with the fattening spray, until Blue Racer washes it off his teammates. In battle, he can also blast lasers from the face on his helmet, which is called using his Nerenko Beam attack. Destroyed by RV Robo.
