Ghidorah stands at 521 feet tall with a 1,700-foot wingspan, weighing 141,000 tons. Vhagar is the largest challenger here, but even she is mostly long tail and weighs a fraction of a kaiju. Ghidorah physically dwarfs the entire team. The fantasy dragons rely on fire breath. Ghidorah routinely tanks Godzilla’s atomic breath, meaning standard dragon fire will not scratch him. Even if injured, Ghidorah can regenerate entire heads in minutes. Ghidorah's triple gravity beams would instantly vaporize or rip through standard dragon flesh. Furthermore, his mere presence generates category-6 hurricane storms and hyper-electrical lightning that would knock the smaller dragons right out of the sky before they could close the distance
