The fanfiction might start with Harry being in a seemingly hopeless situation, like being lost in the Forbidden Forest with a powerful dark force chasing him. Lockhart, who is nearby by chance, decides to step up. He could use his so - called expertise in dealing with dangerous situations, which is more bluff in the original story. But here, he actually uses some hidden knowledge or a magical artifact he has to create a protective shield around Harry, saving him from the approaching danger.
In such a fanfiction, perhaps Lockhart manages to overcome his usual self - centeredness. He could use his knowledge of various spells, which he often brags about but fails to execute properly in the original books. Maybe he finally remembers the correct incantation at a crucial moment to save Harry from a dark wizard or a dangerous magical creature. For example, if Harry is being attacked by a basilisk, Lockhart might remember the spell to stun it and save Harry just in time.
Well, it could be that Lockhart has a change of heart due to some event. He realizes the importance of Harry to the wizarding world. So when Harry is in danger, like being trapped in a cursed area, Lockhart uses his charm skills to get help from other magical beings. He might charm a group of centaurs to help him rescue Harry, relying on his ability to talk his way into situations, but this time for a good cause.
It might be a magical creature that has been corrupted by dark magic. For example, a hippogriff that has been turned evil. It attacks Harry when he's out exploring. Lockhart, who has some knowledge of magical creatures, tries to calm it down at first but when that fails, he has to use more forceful magic to save Harry from the enraged hippogriff.
Well, it might be that Harry Potter is accidentally transported to a non - magical realm where he is in trouble because he doesn't understand the Muggle world completely. The Queen, who has some knowledge of magic or is in contact with a secret magical society, discovers Harry and saves him from the perils of this strange new world for him.
One possibility could be that Voldemort has a sudden change of heart. Maybe he realizes that Harry is the only one who can truly understand his loneliness and power. So instead of killing Harry, he decides to save him from a dangerous situation, like a powerful dark magic that even Voldemort fears could destroy the wizarding world if not controlled, and in the process, they form an unlikely alliance.
In the 'Harry Potter Saved by Demons' fanfiction, perhaps the demons are not as evil as they seem in the traditional sense. They might be outcasts from their own demon realm. When they come across Harry, they recognize his power and the danger he's in. They decide to save him because they believe that by doing so, they can change the fate of both the wizarding world and their own world. So they use their unique demon abilities to keep Harry safe from harm.
Well, perhaps the Winchesters, who are known for hunting supernatural beings in their own universe, find a way into the Harry Potter world. Maybe they sense some dark magic that the wizards in Harry Potter's world can't handle on their own. They then use their skills and knowledge of the supernatural to save Harry from a powerful dark wizard or a dangerous magical creature.
Well, it could be that Hera, perhaps using her divine powers, steps in when Harry is in a really tough situation in the wizarding world. Maybe she saves him from a powerful dark spell or a dangerous creature. For example, when he's facing Voldemort, Hera could use her magic to shield Harry and give him the strength to fight back.
Well, one possibility could be that Arcturus Black uses his powerful magic skills to rescue Harry from a dangerous situation. Maybe Harry is trapped in a dark wizard's lair, and Arcturus arrives just in time to fend off the bad guys with his advanced spells.
Perhaps Voldemort has cast a powerful spell on Harry that the normal wizarding community can't break. But the house elves, with their different kind of magic, are not affected in the same way. They detect Harry's plight and use their loyalty and cleverness. For example, they might create a magical shield around Harry that slowly weakens the dark spell, eventually saving him.
One possible plot for this fanfic could be that Dumbledore, seeing Lockhart's incompetence, decides to give Harry a chance to teach. Harry, being humble, initially doubts himself but then realizes he has a lot to offer. He starts teaching spells and defensive techniques that he has learned from his own adventures. He also uses his Gryffindor courage to inspire the students, and along the way, he might even discover some new ways to fight the Dark Arts that he hadn't thought of before, all while dealing with the challenges of being in a position of authority at such a young age.
One possible plot could be that L, with his extraordinary detective skills, discovers a plot against Harry Potter early on. He might use his intelligence network to find out about Voldemort's plans and then intervenes at a crucial moment. For example, when Harry is about to be attacked by Death Eaters, L shows up and uses his strategic mind to outwit them and save Harry.
