Origin - Possibly originating in India after underground nuclear tests in 1999, King Cobra found its way to the Japanese mainland in the year 2002 where he made his home at the foot of Mt. Fuji. Since then, disappearances of hikers, and tourists are reported throughout the area attracting the HEAT team from America to investigate. However after sneaking past the military, HEAT is confronted by a nearly complete KIRYU dispatched by the JSDF. However just in time, Zilla arrives and battles the machine, but JSDF apprehends the team and takes them to their mobile headquarters where Dr. Ifukube, one of Kiryu's early test pilots (Before Akane in GxMG) is recognized by Mendel Craven as they have worked together several years before the first Zilla attack in NYC. After a long debate, Dr. Ifukube who first thought that Zilla was behind the attacks on the many people decides to call of Kiryu from battle, but just then, the mobile HQ is attacked and the roof is ripped off. HEAT and Dr. Ifukube are then face to face with King Cobra, the true culprit of the disappearances! Dr. Ifukube is pinned down by the serpant's venom and Monique takes over Kiryu's controls and has the robot battle King Cobra as Nick, and Mendel free Dr. Yokiko Ifukube, Elsie and Randy. Suddenly Zilla arrives and begins to attack King Cobra who is constricting Kiryu, but is then blinded from the snake's venom. King Cobra makes a quick escape with Zilla on his tail using his nose to track the fleeing serpant. The following day, Kiryu's systems are repaired and is dispatched with Dr. Ifukube and Mendel at the controls, Nick and Monique tracking Zilla, and Elsie and Randy searching for the cave where King Cobra has taken his victims. In Tokyo, King Cobra erupts from the ground and begins shooting his venom at people below, pinning them down! As he goes in for the kill, Zilla arrives still blinded. The snake then constricts Zilla and in his confusion the reptile fires his thermonuclear breath everywhere! However just before being suficated to death, Kiryu arrives and uses cables from its shoulder to wrangle King Cobra off of Zilla. Soon one of the White Heron Jets, Mendel uses a hose to spray people below with the Anti-Venom, setting them free from the gluey substanance. Without hesitation, King Cobra strikes Kiryu's head and shuts down its systems. Meanwhile Zilla regains his sight after Nick sprays the Anti-Venom onto the creature's eyes. King Cobra hisses as Zilla tackles the serpent into Tokyo Bay where he knocks it out cold. This gave G-Force enough time to come in and send the creature to Monster Island Sight B. Back on Mt. Fuji, Elsie and Randy free the people captured by King Cobra, and Craven assists Dr. Ifukube in repairing Kiryu for its future battle with a much deadlier beast. Years later, King Cobra will be under control of the Xilians and attack Paris along with Kamacuras.
