I really liked 'Harry's New Family with Regulus'. In this fanfic, Harry's adoption by Regulus leads to a whole new dynamic in the wizarding world. It shows how they both grow together, with Harry getting to experience a more stable and loving family environment. There are also some cool sub - plots about how the other characters react to this new situation.
There's a fanfic called 'Adopted by the Starks: Peter Parker's New Life'. In this one, Peter is adopted by the Starks. It's really interesting as it combines the high - tech world of the Starks with Peter's down - to - earth personality. It has a lot of heartwarming moments as Tony Stark becomes a sort of father figure to Peter.
One great fanfic could be 'A New Beginning for Ruby'. It delves into how Ruby's adopted family helps her grow in a different environment. They support her Huntsman training in unique ways and she forms new bonds with her adoptive siblings.
One great 'Harry Regulus' fanfic is 'The Lost Prince'. It delves deep into the relationship between Harry and Regulus. The story shows how Harry discovers Regulus's past and how it impacts his own journey. The character development is well - done, and the plot keeps you hooked from start to finish.
A really interesting fanfiction is the one that explores Regulus Black's connection to the Marauders through Harry. It's set in a post - Voldemort world where Harry discovers some long - lost journals of Regulus.

It's full of mystery and revelations that keep you hooked till the end.
One great fanfic in this genre is 'The Sannin's New Apprentice'. It delves deep into Naruto's neglected past and how his life changes after being adopted by the Sannin. The story focuses on his training and the unique bond he forms with each of them. Another interesting one is 'Naruto: Sannin's Legacy' which shows Naruto growing in power and wisdom under their guidance, while also exploring his new family dynamics.

There's also 'Voldemort's Claim on Harry'. It shows a different aspect of Voldemort's possessiveness. Instead of just physical possession, it's more about his claim on Harry's power and potential.

The story is full of adventure as they face various dark forces together. It also delves into Harry's emotional journey of finding a new family in Damemon.
One plot twist could be that Regulus is not actually dead but was in hiding all this time. And his reason for adopting Harry could be related to some dark secret he's trying to protect. Maybe it has something to do with Voldemort and a way to defeat him that only Harry can be a part of.
There's a fanfic called 'Hermione: The Adopted One'. In it, Hermione is adopted into a family that has a very different magical heritage.
