Sierra Prince-Black (femharryxTomriddlexLoki) (On hold)

Sierra Prince-Black was kidnapped by Albus Dumbledore from her parents Sirius Black and Severus Snape. Albus Dumbledore made a fake prophecy to kill the "dark" Lord Voldemort. Albus placed Sierra with the Potters and had them illegally blood adopted her but what they didn't know that when they tried to adopt her, her features stayed as her parents Severus and Sirius. When the dark Lord hit the Potter's, Voldemort tried to kill Sierra but something happened, Voldemort didn't try to kill her, it was Dumbledore. The killing curse bounced off Sierra back to Voldemort. Dumbledore then took Sierra to the Dursleys. But Dumbledore or anyone at Hogwarts except Sirius and Severus knew that Sierra turned out to be a Metamorphmagus and had eidetic memory of her real parents, Dumbledore kidnapping her, Dumbledore turning to kill her when Voldemort was there, her parents talking about the wizardry world.
From November 1st, 2001, Sierra Prince-Black became the most powerful witch in the world, more than Dumbledore and Merlin. She became the smartest girl at the age 23 mentally and 11 physically but graduated high school at 6 years old, college at 10, and more even when her Metamorphmagus made her look like a 15-22 year old when she was only 2. She matured at the age 2 when her Metamorphmagus made her look like see was older. She was able to read, write, walk, and talk at the age 1. Severus taught Sierra before she was kidnapped kindergarten to 8th grade in only 8 months and she got kidnapped on October 20th, 2001 when her birthday is February 14, 2000. What Dumbledore doesn't know that Severus and Sirius remembers being soulmates and having Sierra, and they both hate Dumbledore and the Potters and dumped them before Severus and Sirius got married right after graduating from Hogwarts without the Potters and Dumbledore knowing who Sierra's real parents are.
I don't own Harry Potter the owner is JK Rowling. There will be Marvel and bashing of Weasley, Dumbledore, and Granger.
