Soldat J
Only known surviving member of the Soldato Battalion, a series of combat cyborgs developed by the Red Planet's leader, Abel. They would function as commanders of the J-Ark fleet, and perform Fusion with them to fight the Z-Master. Abel's extensive preparations would not be enough, however, as the failure to unite Soldato, Alma bioweapon, living computer, and J-Ark battleship into a cohesive team would lead to the failure of the world's defenses and, eventually, the planet's mechanization. As a Cyborg, Soldato J has impressive strength and speed. The green scarf attached to his armor can extend and harden into a pair of wings for flight, and the left gauntlet contains a Radiant Ripper, an energy sword. While normally used with both hands, the Radiant Ripper can be used while still attached to the gauntlet, as seen in FINAL.
As one of the two surviving members of the Battalion, Soldato J 002 fought alone (his J-Ark's main computer—Tomoro 0117—had been lost to Zonder infection and his J-Ark was sent into space to protect its infant Alma onboard), going so far as to confront Arm Primeval, one of the leaders behind the offensive on his world. J would confront Arm alone, and barely lost their confrontation, forced to flee into the wasteland that was now his planet. He was subsequently captured by his own living computer—transformed into the Zonderian Pinchernone—and converted into the Zonderian Pizza, the memory of his proud past sealed away.
As Pizza, he and Pinchernone would accompany the Zonderian "terminal" program Pasder to the "Blue Planet"—Earth—with the order to infect all of humanity with Zonder Metal. Even as a Zonderian, however, Pizza would have brief flashes of the time before he was mechanized. He became a great rival of the GGG Mobile Unit commander Guy Shishioh; through his duels with Guy, his old pride began to recover, along with his a sense of his old purpose. In a burst of defiance, he protected his rival from a direct attack from Pasder, leaving him critically wounded. He would be saved by his Arma, who had landed on Earth and had adopted the identity of Ikumi Kaidou. Kaidou performed Purification on Pizza and Pinchernone, restoring to them their true forms and memories.
Following his restoration, Soldato J would dedicate himself to his original mission once again: to destroy the Z-Master. To this end he would re-unite with his team in his J-Ark (crashed within Mt. Aso in Kyūshū, Japan) and wait for the arrival of the 31 Machine Primevals. Upon the Primevals' arrival on Earth, he showed just how powerful the original Red Planet fleet could have been had it been properly organized. They began an independent mission to destroy the Primevals—ignoring the battles of the Gutsy Galaxy Guard, going over their heads and even clashing with them head-on. As J and GGG realized they had a common goal, however, they began to grudgingly help each other to defeat the 31 Primevals.
