King Cobra first appeared in Japan, attacking hikers with an adhesive liquid and storing them for food. When H.E.A.T. arrived soon thereafter, the mighty serpent interrupted a battle between Godzilla and the Robo-Yeti, blinding Godzilla with its glue-like spit and badly damaging the Robo-Yeti with its constricting coils and fangs. Despite his inability to see, Godzilla chased King Cobra away, and eventually the two ended up in Tokyo. Fully repaired, the Robo-Yeti was sent to assist Godzilla, but King Cobra was not as merciful this time, completely destroying the machine. By now, however, the spray blinding Godzilla had been dissolved by H.E.A.T., allowing him to attack King Cobra head-on. Apparently slaying him with his atomic ray, Godzilla tossed the snake into Tokyo Bay.
It became obvious that King Cobra had survived the encounter, however, when he later showed up on Site Omega as part of the Leviathan Aliens' plan for global conquest. Fully under their mind control, King Cobra was sent to attack Paris alongside the Giant Bat. When H.E.A.T. managed to disable the aliens' mind control device, King Cobra fought back against his would-be controllers, but the firepower of their warships was too much for him, and he was rendered unconscious.
Sometime later, it was revealed that King Cobra was among the mutations corralled on Major Hicks' Monster Island, kept separated from the other monsters within a containment field. Thanks to the efforts of a terrorist group known as S.C.A.L.E., however, King Cobra was freed and immediately engaged in a battle royal involving Crustaceous Rex, the Giant Bat and Skeetera. Eventually, the containment fields were brought back online and order was restored to Monster Island, sealing King Cobra back in his pen.
In an alternate future where the Earth was overrun by genetically engineered monstrosities known as Dragmas, Hicks, in a last-ditch effort to combat the beasts, released all the monsters from Monster Island, which presumably still included King Cobra. Unfortunately, the plan failed, and they were all killed by the powerful dragon-like creatures. |
