Godzilla has the height of 393 feet (119.8 meters) and a total length of 771 feet, NO WINGS, featuring the classic maple-leaf shaped dorsal plates, a rounded tail tip, small reptilian eyes, and heavily armored crocodilian scales. However, official on-screen data marked a substantial weight spike, listing him at a massive 164,000 tons due to an immense increase in raw muscle mass and bone density. This physical conditioning dramatically altered his combat style, shifting him away from a slow brawler into an incredibly fast, highly aggressive predator capable of dropping onto all fours to charge at high speeds and slash fiercely with his claws. His primary superpower remains the Atomic Breath. he can now overcharge his internal nuclear core to drill clean through the Earth's crust directly into the Hollow Earth in mere minutes, alongside possessing a near-instant healing factor and a prehensile tail that he uses fluidly to whip, grapple, and pin down opponents.

Mothra is a giant moth with a sleeker, more predatory, insectoid appearance, standing 52 feet tall with a massive wingspan of 803 feet that features glowing bioluminescent patterns mimicking Godzilla's eyes to ward off predators. Her physical traits deviate from past fluffy incarnations, sporting elongated, wasp-like legs capable of pinning opponents, a concealed abdominal stinger injected with a powerful paralyzing toxin, and the ability to shoot high-pressure, blinding silk webs to trap rival Titans. Her relationship with Godzilla is defined as a profound, ancient, and highly unique symbiotic bond—a connection Monarch scientists describe as "cross-species maternal or romantic symbiosis" where they can communicate across continents through a specialized bio-acoustic frequency. As the "Queen of the Monsters" to his King, Mothra acts as Godzilla’s ultimate ally, actively tracking him down to soothe his rage, fighting to the death alongside him.
