The plot could be that Colin accidentally uses a time - turning device and ends up in the past when Lily Potter was at Hogwarts. He initially panics but then realizes this is a unique opportunity. Colin befriends Lily and they have adventures together. He learns about her hopes, dreams, and her relationship with James Potter. When he returns to his own time, he has a new - found respect for Harry and his family. He uses the knowledge he gained from the past to help Harry in some way, like giving him advice based on what he learned about Lily's character and her experiences.
I'm not sure there are a lot of fanfics specifically about Colin and Harry's mother. However, it could potentially explore an interesting relationship. Maybe Colin discovers something about Lily Potter's past that no one else knew, which could lead to an adventure in the wizarding world. It could also show how Colin's admiration for Harry extends to his family.
Well, it could be that Blaise stumbles upon an old diary or artifact that belonged to Harry's mother. This discovery sets him on a path to understand more about her and, in turn, about Harry. It might lead to a series of events where Blaise has to protect this new - found knowledge from dark forces in the wizarding world who would use it for evil.
Perhaps in the fanfiction, the owl was a magical anomaly. It was attracted to Lily Potter's pure heart. The owl had the power to transform into a human - like form briefly. Lily discovered this and they formed a pact. The owl - human would protect Harry when she couldn't. So when Voldemort came, the owl - human fought valiantly, but was overpowered. However, it left a magical imprint on Harry that would later help him in his battles.
Well, perhaps Harry uses his magic skills like the Shield Charm to protect Colin from various dark spells or dangerous creatures. For example, if there are Death Eaters around, Harry could quickly cast a Protego Maxima to form a large protective shield around Colin.
Perhaps the story could revolve around the Scarlet Witch guiding this 'little Harry Potter' in learning about magic in a different way. Since she has such unique powers, she could teach him things that Hogwarts doesn't. For example, she might show him how to manipulate reality on a small scale, which would be both exciting and dangerous for the young wizard. It could also involve her using her powers to shield him from Voldemort's influence in a more direct way than Dumbledore and the Order of the Phoenix ever could.
In the fanfic, the main challenges for Harry could be related to the limited time he has. He has his own studies and tasks to attend to, like preparing for exams or dealing with the mysteries of the Chamber of Secrets. Yet, he still has to find time to protect Colin. Also, the magical environment itself can pose challenges. There could be spells that are difficult to counteract while protecting Colin, especially if they are new or dark magic.
The fanfic could center around Harry's life outside of the main events of the books. For example, it could explore his summer holidays in more detail. He could be spending time in the Muggle world and using his magic in creative ways to solve normal, everyday problems. He might use magic to help his neighbor fix a broken fence without the neighbor realizing it was magic. This would add a new dimension to his character and show how he can adapt his magical abilities to different situations.
Well, there's a fanfic called 'Colin Creevey and the Mystery of the Lost Spell'. In this, Colin stumbles upon a lost spell and tries to figure out its origin and purpose. It's really exciting as it has him teaming up with some unexpected characters. Also, 'The True Colin Creevey' is a fanfic that delves deeper into his character, showing his growth from an eager first - year to a more mature student.
Perhaps Alice is a new student at Hogwarts who brings with her a strange charm in the form of a lemon. Harry, being curious, gets involved with her and the mystery of the lemon. It could turn out that the lemon is a key to an ancient wizarding secret. As they explore the secret together, they face many challenges and also develop a romantic relationship. Their journey might involve solving puzzles, facing dark wizards who also want the lemon's power, and ultimately saving the wizarding world in a new and unexpected way.
A plot could involve Colin getting into trouble while trying to get an exclusive interview with Harry for the school newspaper. He might accidentally stumble upon a secret meeting of a dark wizard group, and Harry has to rescue him. This would add an element of danger and mystery to the fanfic. It could also show Colin's growth from a naive, star - struck student to someone who can handle difficult situations.
