Summary
Twins, Harry Potter and Onyx Potter, were separated at birth.
Onyx, marked as the Boy Who Lived, was left on the doorstep of Petunia and Vernon Dursley, doomed to a childhood of cold stares and cupboard doors. Meanwhile, his twin brother, Harry, was taken by Sirius Black and hidden from the world—raised with love, firewhisky-scented lullabies, and the fierce protection of the Black family name.
In time, the name Harry Potter faded away, replaced by something new—Hadrian Potter-Black.
Twelve years passed.
On the Hogwarts Express, somewhere between Pumpkin Pasties and whispered secrets, Hadrian locked eyes with a boy who mirrored his face. Confusion. Recognition. Shock.
His world tilted.
His twin stood right there—unaware, unloved, and unknowingly bound to him by blood and fate.
And in that moment, chaos began.

Summary
“So you’re my dad,” Harry said to the large, blond one. The one with the hammer. Supposedly a god, even.
“Yes, I have conceived you myself!” His ‘father’ said with a huge, beaming smile.
“With your brother,” Harry said very slowly, very carefully. “Who is apparently my mother.” Harry gave the tall dark-haired one a good, long look. Yes, there were similarities between their features, even Harry could see that. Hair, eye-colour, the shape of their nose and mouth.
In which Harry is the product of a prank that Loki once played on Thor. But hey, at least he's not a horse, so there's that.
A series of vignettes about Harry's life with the Avengers while getting to know his new parents.
