He often gets hurt in battles. For instance, being slashed by a monster's claws or stabbed by a magical weapon. Another common way is through magic spells cast by enemy sorcerers or demigods, which can cause internal injuries or weaken his powers.
In many Percy Jackson fanfictions where he gets hurt, it often leads to his friends rallying around him. For example, Annabeth might use her wisdom to find a way to heal him quickly. His demigod powers could also play a role in his recovery, like his connection to water might help soothe his wounds if they're burns or something related to fire. It's a common trope to show his vulnerability and the strength of the bonds he has with others in these situations.
Another theme is isolation. Sometimes, when Percy is hurt, he may isolate himself from his friends, thinking he's a burden or that he needs to deal with his pain alone. This theme often leads to his friends having to break through his barriers and show him that he's not alone, which is a really heartwarming aspect of many 'Percy Jackson Hurt Fanfiction' stories.
During a battle at Camp Half - Blood, Percy faced a powerful monster. The beast's claws raked across Percy's back as he tried to dodge. Percy cried out in pain. The scratches burned like fire. He turned and fought back with all his might, using his water powers to his advantage. However, the injury weakened him. His friends noticed his struggle and joined the fight. Together, they finally defeated the monster, but Percy was left with a painful injury that would take some time to heal.
Perhaps it's a gift from his father, Poseidon. Since Poseidon has control over the sea and all things related to water, he might have some connection to a power that gives Percy wings, like as a way to help Percy reach new heights both literally and metaphorically.
In the fanfic, it could be that Percy gets Triton as a gift from Poseidon. Triton could be initially reluctant to be with Percy, seeing him as an upstart half - blood. But as they spend time together, they start to understand each other better. Triton might help Percy improve his control over water, especially in more complex and powerful ways. They could go on quests together, like finding a lost ancient sea artifact that has the power to either save or destroy the world of the sea gods.
One great 'Percy Jackson Hurt Fanfiction' is 'The Wounded Hero' on Fanfiction.net. It shows Percy dealing with the aftermath of a really tough battle where he's physically and mentally hurt. The author does a wonderful job of portraying his struggle and how his friends try to help him heal.
There shouldn't be any legitimate fanfiction with such a plot. The Percy Jackson series has a certain set of rules and moral and ethical boundaries within its fictional universe. The idea of Percy getting Hera pregnant is not only out of character but also violates the general tone and values of the series.
In such fanfictions, Percy's character is often explored through his resilience. For example, if he's physically abused, we see how he still tries to fight back or find a way to escape, which shows his determination. His loyalty also comes into play as he might not want to burden his friends with what he's going through.
