Harry Potter Forgotten By Parents Fanfiction Slytherin の小説・ストーリー

The niche you're describing sends me into a deep dive every time. I gravitate toward that specific hurt/comfort angle where the biological family fails utterly, and the chosen family—often the Marauders, Sirius specifically, or even a mentor Snape—steps in. My method isn't about a single platform. AO3 is my foundation; the tag system is indispensable. You'll want to filter for tags like 'Betrayal', 'Abusive Dursleys' (but dialed up), 'Good Friend Sirius Black', and 'Found Family'. The 'James and Lily Potter Bashing' tag is a direct line to what you want, but it often pairs with 'Weasley Bashing' which I tend to skip.

Don't ignore the older archives like FanFiction.net. The search function is rougher, but some absolute classics in this trope are buried there from the mid-2000s. I found a gripping one last year where Harry is purposefully left with the Dursleys as a 'character test' by a manipulative Dumbledore, and the fallout with his parents' portraits in Grimmauld Place was brutal. Just be ready to sift; the tagging isn't as precise. For me, the real finds often come from following author bookmarks on AO3 of writers who specialize in this angst. Their curated lists are gold.

If you're looking for a specific fic like that, you've probably already hit the big three—Archive of Our Own, FanFiction.Net, and maybe even Wattpad if it's older. I spent an afternoon trying to hunt down that exact title a while back. The thing with these 'forgotten brother' plots is they often get written under different names or as part of a larger series, and sometimes they just vanish when an author deletes their account.

I had more luck with AO3's tagging system, searching for 'Harry Potter brother' or 'OC Potter brother' and then sorting by kudos. The filters for 'complete works only' and 'word count > 50k' helped narrow it down to stories with enough substance to actually develop the premise. You might also try adding 'Slytherin Harry' or 'Grey Harry' to the tags, because a lot of those fics feature an older sibling as a guiding figure. Don't sleep on the collections feature, either—sometimes users curate lists for 'Potter Family' AUs.

Another angle is to look for author names you recognize from other big brother-centric fics. If you find one you like, check their bookmarks. Writers often bookmark stories with similar vibes to their own. I found a fantastic, nearly forgotten fic on FFN that way, buried in someone's favorites from 2012. The prose was a bit clunky at the start, but the dynamic between Harry and this invented older brother who was secretly a curse-breaker was surprisingly tense and well-plotted. It's a shame the author never finished it.

I've seen this title pop up a few times, and from what I remember reading, the central idea revolves around a previously unknown older sibling for Harry. The story usually kicks off with someone—often a goblin at Gringotts or a portrait at Hogwarts—revealing that James Potter had a son from a previous relationship who was hidden away for his safety. This brother, often named something like Charlus or Henry, is typically portrayed as more politically savvy or magically trained than Harry, having been raised in secret by a different guardian, maybe even a different magical culture.

His arrival throws everything into chaos. He's not necessarily a villain, but his presence recontextualizes Harry's entire life. The 'forgotten' part often refers to magical contracts or family magics that were blocked, which he comes to unseal. A lot of the plot hinges on how Harry, often already struggling with his fame and trauma, reacts to this sibling who seems to have everything he lacked: knowledge of their parents, a stable upbringing, a clear purpose. The dynamic with Dumbledore is almost always antagonistic in these stories, framing the Headmaster's actions as manipulative for hiding this truth.

These narratives tend to be power fantasies at their core, focusing on the brother teaching Harry 'real' magic or introducing him to ancient family rituals. The main conflict usually shifts from Voldemort to internal family drama and political maneuvering within the Wizarding World, with the brothers having to learn to trust each other. The execution varies wildly; some versions make the older brother a Gary Stu, while others explore his resentment at being the 'spare' kept in the shadows. The plots I've clicked on often lose steam after the big reveal and the initial training montages, struggling to integrate the new character meaningfully into the stations of canon.
