Well, perhaps in the fanfiction, the Potter family has some allies that help them in rescuing Harry. For example, they might team up with some powerful but little - known magical families. Or it could be that Lily Potter has a special connection to Harry that leads them to his location even when he is hidden away. They could then use a protective spell to keep him safe from further harm.
In this fanfiction, it's possible that the Potter family has a premonition about Harry's danger. So they set out to rescue him. They might have to traverse through dangerous magical terrains filled with dark creatures. Once they find Harry, they could bring him back to their family home, which is protected by ancient magic spells. There, they could raise him with love and train him in magic from a very young age, changing the course of his life and the wizarding world's future.
One possible scenario could be that Harry grows up on the streets, learning to fend for himself and developing a tough exterior. He might encounter some kind of mentor figure who helps him discover his magical abilities in a very different way than in the original story.
One possible scenario could be that a powerful wizard or witch, perhaps someone who knew James and Lily Potter well, comes to rescue baby Harry. They might use magic to bypass the Dursleys' defenses and take Harry away to a safer place, like a hidden wizarding community.
One possible scenario could be that Peeta discovers Lemon in a dangerous situation, like trapped in a collapsing building. He uses his strength and courage to get Lemon out safely.
Perhaps in the fanfiction, Harry Potter's death occurs because he tries to rewrite a powerful magic spell that goes horribly wrong. He was always known for his bravery and willingness to take risks in the original series, so this could be an extension of that. His death would then be a tragic consequence of his own curiosity and desire to push the boundaries of magic.
One possible scenario could be that Harry is exiled due to false accusations of dark magic. Maybe the Ministry of Magic, fearing his power after the defeat of Voldemort, spreads lies about him being a threat. Another could be that he chooses exile to protect his friends from a new, unknown danger that is targeting him specifically.
A plotline could be where Harry is in a wizarding duel against a powerful and evil opponent. He's outmatched and on the verge of being defeated when Greengrass steps in. She has a special magical artifact that she uses to turn the tide of the duel and rescue Harry. After that, they might embark on a journey together to find out more about the origin of the evil opponent and how to defeat them once and for all.
One possible plotline could be that Voldemort rescues Harry because he sees potential in him to be a powerful ally in his quest for total domination. Harry, being evil, might have already started to dabble in the Dark Arts on his own and Voldemort wants to harness that. Another plotline could be that Voldemort saves Harry from some other threat, like the Ministry of Magic which has turned against Harry for his evil deeds. This could lead to a strange alliance between them as they both have a common enemy in the Ministry.
One possible scenario is that Harry discovers the Force during his time at Hogwarts. Maybe there's a hidden chamber or an old artifact that unlocks this power within him. Another scenario could be that he meets a character from a different universe who teaches him about the Force. For example, a rogue Jedi who has somehow ended up in the wizarding world.
One possible scenario could be that Harry discovers a hidden magical passageway in his tiny bedroom at the Dursleys'. It could be a secret portal created by a well - meaning wizard long ago to help any oppressed magical being in the Muggle world. Harry stumbles upon it while looking for a lost sock or something mundane. Another scenario might be that a group of friendly magical creatures, like house - elves, conspire to help him escape. They create distractions around the Dursley house, like making the pots and pans fly around and creating chaos, which allows Harry to slip away unnoticed.
One possible scenario could be that Voldemort punishes Harry Potter by using the Cruciatus Curse on him. In the wizarding world, this is a very cruel form of torture. Another situation might be that Voldemort imprisons Harry in a dark and desolate place, like the dungeons of Malfoy Manor. He could also force Harry to watch as he harms his friends, which would be a psychological form of punishment for Harry, who values his friends highly.
