Biography

Liver Primeval, along with the other 31 Machine Primevals, were summoned to Earth by Pasder. While its and the other Primevals' bodies were destroyed by Mic Sounders the 13th's soundwave, their core remained intact and landed on Earth. Liver would ended up assimilating a human and attacked a military supply ship in the Philippines, fusing with them both. After meeting with the other Seven Magnificent Primevals under orders from Pagliaccio, the group attacked the GGG Orbital Base. Liver Primeval and his comrades would then infiltrate GGG Orbital Base by having Rib Primeval disassemble their atoms to enter the base through a 0.02mm crack on the wall.

Joining forces with Rib Primeval, both Liver and Rib face FuRyuu, RaiRyuu, GoldyMarg and Volfogg. Despite the Brave Robots managing to wound them, Liver would use his regenerative powers to heal themselves. Trapping the heroes in a vicious cycle of wounding and healing, GoldyMarg tore open the wall of the room they were in, ending the fight as both Ribs and Liver were sucked out of the GGG Orbital Base. Thus, they requested Arm Primeval to change their strategy by converting the base's engine into a Zonder Metal Plant. However, this also failed, as Taiga ordered to have the engine severed and destroyed.

The Primevals then fused with their respective ships and started blasting the GGG Base, while Liver managed to regenerate its damaged allies. However, this tactic ultimately caught the attention of Soldato J and the GGG, and as such, they used J-Der to destroy Liver Primeval by pulling its core out and purifying it, rendering ot inactive. Liver's core is then stored on the J-Ark.

Later, Liver, along with all captured Machine Primevals, would be taken out from the J-Ark to fuse with Arm Primeval, Pagliaccio, and Pasder to become Z-Master, in the end, the heroes destroyed Z-Master, erasing all Primevals from existence.
