It's highly inappropriate. The Harry Potter universe is a world of magic, friendship, and adventure. Adding sexual content through fanfiction to a character like Lily Potter goes against the essence of what the series represents. It also sets a bad example for those who look up to the series and its characters.
Perhaps James had some hidden magical ability that he was unaware of until that moment. It could be something that was passed down through his family but had never manifested before. This ability could have protected him from Voldemort's killing curse. Or, it's possible that there was a plot by some other characters to save James. There could have been a group of wizards or witches who had been secretly working to keep James alive because they knew his importance in the fight against Voldemort. They might have used some sort of time - turning magic or a protective charm that Voldemort couldn't break through.
There could be. Fanfiction is a vast world where all kinds of wild ideas are explored. Since both the character of James Potter from Harry Potter and the Joker from Batman are quite well - known, it's not far - fetched that someone has written a fanfic where James Potter takes on the persona of the Joker. It could involve a really interesting plot where the magical world of Harry Potter collides with the dark and chaotic world of the Joker.
One popular type of fanfiction about James Sirius Potter might be his adventures at Hogwarts. Writers could explore his relationships with his friends and family, like how he deals with the legacy of his famous father, Harry Potter. Maybe he gets into some mischief in the same way his father did, but also has to face new challenges specific to his own time at the school.
In these fanfictions, James is often shown as a strong - willed character even in his hurt. For example, in some stories, he may be physically injured but still tries to protect his friends. He's also depicted as someone who has a deep sense of loyalty, so his hurt might make him worry about how it affects those around him.
One negative impact is that it can distort the original characters and their relationships. In the Harry Potter series, the characters are complex and have certain values, but smut fanfiction often reduces them to sexual objects, which is disrespectful to the original work.
There's also 'When Pain Meets Comfort'. Here, Harry is suffering from the after - effects of a dark spell. James Potter, who has been observing Harry from a sort of spiritual plane, finally manages to break through and reach Harry. He takes Harry to a magical place where they can talk and James heals Harry's wounds, both visible and invisible, with his paternal love.
One great Hermione, James Potter and Lily Potter fanfiction is 'The Unlikely Trio'. It explores a unique alternate universe where Hermione time - travels and gets involved in the lives of James and Lily. The story is full of interesting character interactions and a well - crafted plot that keeps you hooked from start to finish.
There's 'Lily and James: A Different Path'. In this fanfiction, it explores an alternate universe where their relationship develops in a more complex way. There are some really interesting twists and turns. For example, it delves into how they deal with the threat of Voldemort in a different scenario than in the original books. It also focuses a lot on their individual growth as characters while they are in a relationship.
A major theme is the exploration of the past. Harry never really got to know his father properly. So in fanfiction, writers often take the opportunity to delve into James Potter's life. This could include his time at Hogwarts, his relationship with Lily, and how all of that shaped Harry. It's also common to see themes of redemption, especially if the fanfiction takes a different turn on James' character, perhaps showing him making amends for any mistakes he made in his youth.
