After the Fist, Hair, and Jaw Primevals were defeated by King J-der, all 28 remaining Primevals arrived at the Earth via E.S. window. Their bodies were destroyed by a solitary wave created by the Mic Force and their cores were scattered across the earth. Nerves's core remained dormant until Pagliaccio and Arm transported the remaining cores to Jupiter. Nerves merged with one of Jupiter's moons to ambush the J-Ark, and later 3G. In this form, Nerves was one of four primevals that paralyzed King J-Der with an electrical field. Nerves was defeated by GaoGaiGar with the Goldion Hammer.
