For some, a novel is good enough when it evokes strong emotions or provides valuable insights. It could also be when it meets the expectations of the target audience.
Their interaction would be tense at first. Young Kratos, full of energy and unbridled aggression, might see old Kratos as a threat or an obstacle. Old Kratos, on the other hand, would be more reserved and cautious. But as they start to communicate, they would find common ground in their shared past and their connection to their family.
He recommended "The Alluring Demon: Reborn as a Demon." The female protagonist Qian Yuhan had transmigrated to another world due to an accident and was reborn as a demon. She was originally weak and inferior, but after her rebirth, she changed. She used her elemental power to resurrect herself, becoming strong and decisive. She would no longer be weak and inferior. I hope you like this fairy's recommendation. Muah ~😗
Kratos might win. He has fought and defeated many powerful gods in his own world. He is not only physically strong but also very strategic. He could analyze the Hulk's movements and find his weaknesses. The Hulk, while strong, is more of a brute force fighter. Kratos could use his Blades of Chaos to keep the Hulk at a distance and then strike when the opportunity arises. Also, Kratos has faced opponents much larger than him before and has always found a way to win.
One possibility is that it could focus on a mentoring aspect. Old Kratos, with all his wisdom and experience, could guide young Kratos. Maybe he'd show him different combat techniques or how to better control his rage. It could also be a story of self - discovery for young Kratos as he sees his future self and realizes the potential path he could take.
Tyrion Lannister. He is known for his wit and political acumen. Meeting Kratos, a powerful and straightforward warrior, would create an interesting dynamic. Tyrion might try to use Kratos for his own political games or just be fascinated by his stories of battles from another world.
I don't have a definite answer. It could vary based on how the story unfolds and what the author intended. Maybe when external circumstances forced a shift in focus away from music.
