Little giant
This is an Idea of Draco being raised by giants, now maybe not the typical Harry Potter giants but rather Norwegian giants who have a higher intelligence and use of magic is much greater due to their line of Jotun ancestry.
It all starts with a large female giant walking the forest when one of her children see a tiny dot in the snow, being thirty-five feet tall she would not have been able to see the dot, her child discovers it is a human infant. Her eyes narrow, humans left their young out to die in the unforgivable weather, her kind does not feel the cold due to their Jotun blood. As she brings the small babe close to her face she senses the life within the human babe weakening. She grows nervous, she just recently lost her child and she can't stand to see another, even a human one, die. So she does the only thing she can do and she pulls her magic to the infant putting her magic to save this young one. Suddenly she hears cries come the babe and her heart swelled with joy. The giantess, Brunnhilde, is conflicted for she will have to return the human youngling to the humans, but she cannot part with it
Seven years later against everything Brunnhilde has raised the youngling as her own.
Just imagine Draco being raised by giants and believing he was one but just a runt like Lopt (or Loki). Until his giant mother tells him of him being a human. (Which he first was heartbroken about.) When it gets to the time when Draco begins to show magic she and her children teach Draco all they know but even the giantess knows her youngling needs to be with his own kind. The giantess remembers about hearing about a half giant who works with magical children. There Draco meets Hagrid the half giant who at first is very in wonder about seeing the largest giantess he had ever seen but also seeing the giantess raising a small human boy as her own. Draco only knows Giant-talk and Norwegian so Hagrid tries to integrate him into being a regular human boy.
It would be funny if at first if when Draco is learning to be a human boy, he tries hunting still and hunts both Professor Macgonagall and Mrs. Norris. Of course Hagrid stops him and that's how the deputy headmistress finds out about the "little giant", along with Professor Dumbledore. Both if whom teach Draco to speak english, read, write, and other skills.
(+10 if Draco inherits giant traits through the giantess' magic such as strength, speed, and ability for spells to not affect him, even when if he encounters the troll in the girls restroom the troll feels fear from Draco and when he catches Neville with the strength.)
(+5 Draco has a cute Norwegian name )
