One interesting plot could be that James, having survived, decides to go into hiding with his family in a more secretive way. He uses his survival as a motivation to become a stronger wizard and starts to train secretly, waiting for the right moment to face Voldemort again.
A really fascinating plot could be that James' survival is part of a bigger prophecy. Maybe there was a prophecy that said he had to survive the Killing Curse to be the one to ultimately defeat Voldemort. This would make his survival not just a lucky break, but a crucial part of the wizarding world's future. As he discovers this prophecy, he has to grapple with the weight of this new responsibility while also dealing with the fact that Voldemort will surely be after him again.
One possibility could be that there was some sort of magical interference. Maybe a powerful magical artifact or a spell was in place that deflected the Killing Curse just enough for James to survive. For example, if there was a hidden protection charm on him that he wasn't aware of.
Another plot might involve a character other than Voldemort using the Killing Curse in a moment of extreme desperation. For example, a Hogwarts student who is being blackmailed by Death Eaters and uses it to defend themselves, but then has to deal with the moral and magical consequences. It could show the dark side of the wizarding world even among the so - called 'good' characters.
Well, a great James Potter survived fanfiction is 'James Potter's Redemption Arc'. It could explore how his survival changes his perspective on life and death. Maybe he has to deal with the guilt of leaving his family behind in the first place. Then there's 'The Return of James Potter'. This one might show his struggles to fit back into the wizarding world he once knew, as so much has changed since his supposed death.
In some fanfictions, if they survived, they might have changed the whole course of the wizarding war. They could have joined forces with other powerful wizards and witches earlier and potentially prevented Voldemort from gaining as much power as he did in the original story. They might have also influenced the Hogwarts curriculum, emphasizing more on defensive magic against the Dark Arts from an earlier stage.
Some fanfics have the plot where James and Lily travel back to their school days. It's interesting to see how they handle seeing their younger selves and friends. They can also try to prevent certain events that led to bad things in the future. For example, they might try to stop a particular argument between friends that later had far - reaching consequences. It's full of character growth and self - discovery.
A great plot idea could be that in the fanfiction, James Potter comes back as a ghost or some kind of spectral form. He then accompanies Harry on his adventures, giving him advice and helping him in battles. They could also have heart - to - heart conversations about love and family. For example, James could share his experiences with Lily with Harry, and in turn, Harry could tell James about his own feelings for Ginny. This would not only strengthen their bond but also add a new dimension to the Harry Potter universe in the fanfiction.
If Harry uses the Killing Curse in fanfiction, it would greatly change the perception of his character. He has always been seen as a hero who stands against dark magic, so using such a curse would make him seem more morally ambiguous.
One interesting plot could be James Potter using his skills to outwit new and powerful dark wizards that emerge in the wizarding world. He might form new alliances and teach the younger generation his unique magic. Another could be him exploring uncharted magical territories, perhaps finding new spells or magical creatures that change the way magic is perceived in the wizarding community.
A plot could be that James Potter travels back to the time when Voldemort was still Tom Riddle at Hogwarts. He could try to influence Riddle in a positive way, perhaps by befriending him and showing him a different path than the dark one. However, he has to be careful not to change the future too much or risk endangering his own existence and that of his family.
There might be. Fanfiction writers sometimes like to take characters out of their comfort zones and explore darker or more extreme scenarios. But in the official 'Harry Potter' lore, Harry would never casually use the Killing Curse. It's a very serious and immoral spell in the wizarding world.
