Cobra

Cobra are characters in the Godzilla episode "Island of Doom."
They are an international gang of criminals with cobra symbols on their uniforms. They consist entirely of military officers, and are stationed on an island near Australia.
They begin by destroying a weather satellite in order to prevent it from revealing their outpost to the world. The crew of the Calico witness the destruction, and try to alert the authorities in Canberra, but can't get through due to the large amount of radiation on the island blocking their transmissions. Cobra spots them, and tries to blow them up with mines, but Godzilla saves them. Cobra captures them and imprisons them in the tower when they come ashore. But now Cobra has a bigger problem: Their nuclear reactor is overheating, and can't be cooled down.
Godzooky temporarily escapes to call Godzilla again, and Godzilla comes ashore, and begins destroying everything in his path(none of the Cobra agents are hurt or killed). They attack him with missiles, tanks, and planes, but he is unstoppable. He frees his friends, and then throws the reactor into the lagoon and neutralizes the harmful radiation with his lasers. All the Cobra personnel are taken into custody now that their threat to the world is over.
Despite the similarities, this group should not be confused with the organization Cobra from the 1980's G. I Joe toy line and animated series.
