One possible plot could be that the Child Emperor, with his high intelligence and various inventions, is initially intrigued by Garou's self - proclaimed 'hero - hunting' ideology. They might have a series of battles where the Child Emperor uses his technological gadgets to counter Garou's martial arts skills. Eventually, they could find some common ground in their views on the nature of heroes and villains, leading to an unexpected alliance or at least a mutual understanding.
It's really hard to say. The Child Emperor has his amazing technology and intelligence on his side. He can create all sorts of gadgets to attack and defend. But Garou is a really tough fighter with great martial arts skills and the ability to quickly adapt in battle. If the fight is in an open area, Garou might be able to use his speed and agility to dodge the Child Emperor's attacks and get close enough to land a powerful blow. However, if the Child Emperor has time to set up his defenses and traps, he could potentially wear Garou down. So it could go either way depending on the circumstances of the fight.
Well, in the fanfiction, the moment when Cosmic Garou tries to counter Saitama's attacks with his own new - found cosmic powers is really exciting. He has evolved to a whole new level, and seeing how his powers match up against Saitama's is a big part of the thrill. Maybe he creates some sort of cosmic energy blast that Saitama has to dodge or block in an unexpected way.
The anime Terra Formars is a story full of action and survival. In the story, Earth is overpopulated and in need of new resources. Mars is seen as the solution, so they send roaches with the ability to terraform the planet. Years later, the humans sent to Mars find that the roaches have evolved into humanoid - like creatures with incredible strength and abilities. The humans, who are themselves genetically enhanced to some degree, must fight these Terra Formars. There are various characters with different skills and backstories, all trying to either achieve the terraforming goal or just survive in this harsh and dangerous situation on Mars.
Terra Formars is set in a future where humanity decides to terraform Mars. They send modified cockroaches to the planet to break down the soil and make it habitable. But these cockroaches mutate and become humanoid killers. A group of convicts is sent to Mars as part of a mission to exterminate the Terra Formars. The story is full of intense battles and survival struggles as the humans fight against these highly evolved and dangerous creatures on the Martian surface.
One main plot point is the terraforming mission of Mars. Another is the evolution of the cockroaches into the Terra Formars. And the battles between the humans and the Terra Formars are also a key plot point.
The battle between Saitama and Cosmic Garou in the fanfiction would have a catastrophic effect on the environment. First, Saitama's initial attacks might send out concussive forces that uproot trees and scatter them like matchsticks. Cosmic Garou's response could involve creating some sort of cosmic vortex that sucks in everything around it, from small pebbles to large boulders. As the fight progresses, the area around them would become a desolate wasteland, with fires raging from the heat generated by their attacks and the air filled with dust and debris, making it difficult for any living thing to survive in the vicinity.
The main plot points include the initial terraforming attempt with the cockroaches, their evolution into Terra Formars, and the dispatch of the human team. Another key point is the battles between the humans and the Terra Formars, and the discovery of different Terra Formar types and their abilities.
