Earth Guardian

The earth's core has been subject to material changes, and different types of mutant species are attacking all countries on the earth. Various weapons cannot cause harm to them at all. Only powerful artillery shells, missiles and nuclear bombs can destroy ordinary monsters. What's even more serious is that huge monsters that only exist in movies have appeared in the real world. The destructive power and defensive power of these monsters are more powerful than the mutated creatures on the earth. Human weapons cannot cause any harm to these monsters. The helpless humans finally put aside all their grudges, integrated all resources, shared all technologies, and developed human-controlled robots that could barely fight against monsters. Why didn't Ultraman from the movie appear to save us? Have they forgotten us? Who should protect the earth? Who should be the guardian of the earth?
