His powers could become more focused. Kratos might teach him to use his water powers in a more precise way, like creating sharp water blades instead of just large waves.
His powers could become more nature - oriented. For example, he might be able to control animals better, like Artemis can.
Well, Percy already has his own set of powers related to water and being a demigod. But if trained by Kratos, he'd likely become a more well - rounded fighter. Kratos could teach him about different combat strategies and how to use his environment to his advantage, not just relying on his powers. Percy might also develop a more intimidating presence, like Kratos, which could be useful when facing enemies in the fanfiction world.
Well, Percy's power over water is a very versatile thing. He can make water do all sorts of things like form into weapons or shields. Kratos, with his insane strength, can break through almost anything. In a fanfiction scenario, their powers could combine in battle. Let's say they're facing a horde of fire - based monsters. Percy could call up a huge wave of water to douse the flames, and then Kratos could rush in with his blades and start slashing away at the weakened foes. Also, Percy's ability to heal himself in water could be a great asset if Kratos gets injured. He could find a body of water and help Kratos recover, while Kratos could protect Percy during the process.
He'd become more powerful. His combat skills would be enhanced, and he'd have a better understanding of the primordial forces. He might also become more unpredictable in battle, like Chaos itself.
His powers might become more related to fate - manipulation. He could, for instance, foresee certain events related to the destinies of people or creatures. This would give him an edge in battles as he could anticipate the moves of his enemies based on their fated paths.
His powers might become more refined. For instance, his control over water could be enhanced in terms of precision. Instead of just creating large waves, he could manipulate water at a microscopic level, like using it to disarm an enemy by getting into the mechanisms of their weapons. Athena's training could also give him the ability to combine his water powers with strategic thinking. So he could use water to create diversions or traps in a more intelligent way.
His water - related powers could become more refined. Shiva has a connection to water in some Hindu myths, like his role in the Ganges river story. So, Percy might be able to control water in more complex ways, such as creating intricate water sculptures that can also be used as weapons. His ability to manipulate water temperature could also improve, allowing him to freeze water instantly or make it boil on a large scale.
His powers might be enhanced by Stark technology. For example, his ability to control water could be used in more precise ways with the help of Stark - made gadgets.
Percy's reaction would be a mix of confusion and fascination. The world of Kratos is so foreign to him, with different rules and a much darker tone. However, he would also be drawn to the hero's journey that Kratos undertakes in the fanfiction, comparing it to his own journey as a demigod.
His powers would likely become more god - like. He might gain the ability to control lightning, like Zeus. Also, his strength and speed could be enhanced to a much greater degree. His control over water, which was his main power before, could also be amplified and perhaps combined with his new lightning powers in some unique ways.
