One idea could be that Harry grows up with a very different set of values. House elves are known for their loyalty and hard work. So, Harry might be more in tune with serving others selflessly. For example, he could be more eager to help his classmates with their problems without expecting anything in return.
It could be really interesting. Maybe Harry would grow up with a different set of values. House elves are very loyal and hardworking, so Harry might be more attuned to their way of life. He could be more humble and less likely to seek the spotlight like he did in the original story.
Dobby would likely be one of the important house elves. He has shown great courage and a willingness to go against the norm to help Harry in the original series. In this fanfiction, he could be the leader among the house elves in the rescue mission.
Dobby is often very popular in fanfiction. Since he was already a well - developed character in the original series, fanfiction writers like to expand on his story further. He might be shown having more adventures or getting into different kinds of trouble. Another popular one is Kreacher. Writers may explore his complex personality more deeply, perhaps showing a side of him that was not fully explored in the books, like his loyalty to the Black family in new and interesting ways.
He'd likely be more humble. House elves are humble creatures, and growing up with them would instill those values in Harry. He wouldn't be as boastful as he sometimes is in the original series.
Perhaps Harry, being raised by house elves, has a very different view of the wizarding world's social hierarchy. He may see the unfair treatment of house elves as completely unacceptable from a young age and strive to change it. This could lead to him getting into conflicts with some of the more traditional pure - blood families who rely on house - elf labor.
I'm not sure of specific ones off - hand, but you can try searching on fanfiction websites like Archive of Our Own or FanFiction.net. Look for ones with high ratings and positive reviews.
One possible plotline could be that the Potter elves teach Harry unique magic that is different from what he would learn at Hogwarts. For example, they might show him ancient elf magic that gives him an edge in dealing with dark forces. Another could be that the elves raise Harry with a strong sense of family and loyalty, which makes him more empathetic towards those who are often overlooked in the wizarding world, like house - elves themselves.
He would likely be more humble. House elves are known for their selfless service, and growing up with them would probably make Harry less self - centered. He would understand the value of hard work and helping others without expecting anything in return.
He becomes more humble. Elves are used to serving and being in a subservient position. Growing up with them, Harry would learn the value of every being, no matter their status. He'd be less likely to show off his magical abilities like he might have in the original story.
