One interesting storyline could be that Harry discovers his moon powers during a full moon at Hogwarts. Maybe he can communicate with magical creatures that are only active during the full moon. Another could be that his moon powers are linked to a hidden prophecy, and Voldemort wants to steal those powers for himself.
Well, perhaps Harry's moon powers allow him to manipulate time in a certain way, but only when the moon is in a particular phase. For example, during a lunar eclipse, he can go back in time briefly to correct a mistake or gain some important knowledge. And his friends are both amazed and a bit scared by this new ability of his.
One interesting storyline could be Harry Potter using his god - like powers to bring back all the fallen characters in the wizarding world. He could reverse the deaths of Sirius Black, Dumbledore, and Lupin, and they could all help him in a new battle against a revived Voldemort. Another could be him using these powers to completely reshape the wizarding society, making it more inclusive and fair for all magical beings, like house - elves and giants.
One interesting storyline could be Bella discovers her ice powers in a moment of great danger. For example, she's in a forest and a wild animal is about to attack her. Suddenly, her ice powers manifest and she freezes the area around the animal, saving herself.

She uses her powers to create ice barriers and weapons to combat the enemy.
One possible storyline could be Naruto's mutant power being the ability to control all forms of nature energy without the need for training. This would make him extremely powerful and feared in the ninja world. Another could be that his mutant power is related to instant teleportation, allowing him to appear anywhere in an instant, which would change the dynamics of battles and missions.
One interesting storyline could be that his younger siblings are sorted into different houses at Hogwarts. For example, one might be in Hufflepuff while Harry is in Gryffindor. This could lead to some sibling rivalry as well as moments of them coming together to face challenges. Another could be that his younger siblings have unique magical abilities that Harry doesn't possess, and they end up helping him in unexpected ways during his battles against Voldemort.
Well, a storyline could revolve around the mystery of her blindness. Maybe it was caused by a dark spell when she was a baby, and as the story progresses, Harry and his friends try to find a way to reverse it. Meanwhile, she is learning to be independent and strong. She could also form a special bond with some magical creatures that are attracted to her unique situation. For instance, a thestral might befriend her because she can sense its presence without seeing it in the normal way.
Perhaps a fanfiction could show Harry's relationship with his professors in a new light. Some professors, like Professor Snape, might initially be unsympathetic, seeing it as a Muggle weakness. But as the story progresses, they could come to understand the gravity of his situation and help him in their own ways. Dumbledore, on the other hand, could use his wisdom to guide Harry in accepting his condition and still being a great wizard.
One possible storyline could be that Harry discovers his angel wings during a dangerous battle at Hogwarts. The wings give him the ability to fly faster and more gracefully than a broomstick, allowing him to outmaneuver the dark forces. He could use them to rescue his friends from precarious situations, like flying them to safety when the castle is under siege.
Some fanfictions give Harry the power of elemental control. He can manipulate fire, water, air, and earth. This power often comes in handy during duels as he can create barriers of fire or gusts of wind to deflect spells. It also makes him a more formidable opponent against dark wizards who don't expect such a wide range of powers from him.
One cool power often seen in such fanfiction is teleportation. This allows characters to quickly move from one place to another, escaping danger or arriving at crucial moments just in time. There are also powers related to healing, where a character has an extraordinary ability to cure any injury or illness, which can be very useful in the often - dangerous wizarding world.
One possible storyline could be the brother being a Slytherin while James is in Gryffindor, creating a lot of family tension.
