One interesting storyline could be Percy using the Blades of Chaos to fight against a new and powerful monster that the original stories haven't introduced. He might have to learn new combat techniques with the blades to defeat it.
Grover could also be a main character. He could use his nature - related abilities to assist Percy when he wields the Blades of Chaos. For instance, he might be able to sense danger in the environment that Percy can then use the blades to face. Grover could also help Percy find his way in places where the Blades of Chaos' power might be affected by the surrounding nature.
I recommend the following two novels to you:
1. "Douluo: Critical Strike Dual Blades, Bibi Dong Breaks Defense": The protagonist Li Xiaodao transmigrated to Douluo Continent and unexpectedly awakened a pair of god level spirits with natural rank 20 spirit power, a defense breaking blade in his left hand and a critical strike blade in his right. The dual-blade technique made countless Douluo goddesses fall for it.
2. <<Scattered Silver>> The protagonist, Jiang Shui, walks the Jianghu with a pair of chipped sabers. There are also various masters around him. When she was growing from a little white to a god, she had used this pair of chipping knives to cut through the thorns.
I hope you like my recommendation. Muah ~
Kratos is incredibly powerful, but it's hard to say if he's the absolute strongest. Different fictional universes have their own mightiest characters, and it depends on various factors like their powers, skills, and the context of their stories.
The story of Kratos is complex and compelling. He was once a servant of the Greek gods but was betrayed and wronged, leading him on a violent path. As the series progresses, he grapples with his actions and tries to find a way to atone for his sins.
Kratos' height in comics varies depending on the artist's interpretation. But generally, he's depicted as quite imposing and towering over most characters.
