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. Bladder's core remained dormant until Pagliaccio and Arm transported the remaining cores to Jupiter. Bladder merged with Jupiter's moon Thebe to ambush the J-Ark, and later 3G. Bladder was defeated by King J-Der's J-Quath.
