One consequence could be that Percy gains a lot more respect among the demigod community. Controlling Typhon is no small feat, so he'd be seen as an even greater hero. Others might look up to him more and he could potentially become a leader in a more significant way.
In the fanfiction, Percy could potentially control Typhon with the help of his friends. They could all work together, each using their own unique abilities. Annabeth could provide the strategic plans, while Grover could use his nature - related powers to distract Typhon. Percy, with his water powers, could then take advantage of the situation and subdue Typhon. It's all about teamwork and using their combined skills to handle such a powerful enemy.
In some fanfictions, Typhon is not just a mindless monster. He might have motives and desires. For instance, he could be seeking revenge against the gods for imprisoning him. This makes him a more complex character and gives the story more depth. Writers can then explore the moral implications of whether the demigods should just destroy him or try to reason with him.
If Percy was the son of Typhon, his character would go through a major transformation. He'd have to deal with the stigma of being related to one of the most feared monsters in Greek mythology. Initially, he might be ostracized by some of his friends. This would make him more withdrawn, but also more determined to prove himself. He'd start to explore the powers that come with his new heritage, which could be both a curse and a blessing. As he masters these powers, he might gain a new confidence, but also have to constantly battle the urge to use them for darker purposes. His relationships with the gods would also change significantly. The Olympians would be more wary of him, and he'd have to find a way to either earn their trust or defy them.
