Monster Zero (2019)

It was covered in ice when it was firstly discovered. It broke free and known as Monster Zero morely called King Ghidorah. It fought Godzilla but was weak. One of the heads saw a broken cable (i think) and it powered him. it beated Godzilla and made him dead. Mothra decided to fight Monster Zero and sacrifice his life. Godzilla had the feeling to become thermonuclear and became alive again. It was in its Thermo form. It beated Monster Zero.

Although King Ghidorah's design has remained largely consistent throughout its appearances (an armless, bipedal, golden and yellowish-scaled wyvern with three heads, two fan-shaped wings, and two tails), its origin story has varied from being an extraterrestrial planet-destroying wyvern, a genetically engineered Creature.
