Harry the House Elf by Shell
Summary: Harry has been treated as a house elf all his life by the Dursley‘s, because of this treatment, Harry actually turns into a house elf. Of course, this upsets his aunt Petunia.
You can decide if Harry runs away or if the Dursley’s are forced to deal with his new identity. Perhaps Harry isn’t too upset with his change because now he’s no longer the Boy Who Lived, he is a house elf! What’s the big deal anyway. He always treated as was one anyway!
What does Dobby think about Harry’s transformation?
I leave this idea up to you and your interpretation. I myself am not a writer, so I would love for someone who is able to create to be able, to do something with this idea. Thanks.
