Nomenclature: Based on a monster passed down from Odo Island, whom the islanders called "Gojira," which later became "Godzilla." In the United States, he is called "GODZILLA." Appearance: This Godzilla is based on the previous version but has evolved into a more aggressive and sinister form. Sharp yellow-green eyes emit an overwhelming sense of intimidation, and his entire body is covered in rough, keloid-like skin and burns that tell a story of raw radioactive terror. Furthermore, the enlarged three rows of dorsal fins and sharp spikes on both shoulders characterize a silhouette reinforced for a more ferocious impression. Attack Behavior: - Stomp/Tail Attack: Sweeps through the city, crushing buildings and crowds. - Bite/Claws: Picks up ships and trains in his mouth. - Atomic Breath: His greatest weapon. His dorsal fins glow pale blue via an implosion method, and he exhales a pale blue heat ray equivalent to a nuclear explosion from his mouth. A single strike devastates all buildings within a radius of several kilometers and generates a mushroom cloud. Because he consumes significant energy, he cannot fire in rapid succession. Details: As a monster, he does not understand human language and, of course, cannot speak it; he can only emit beast-like roars or threats.
