Hello everypony, FoxFira here! I am going to attempt the challenge MEGAandBIT has given for a Harry Potter being raised by Zecora.
Disclaimer!- I own nothing of this idea or My Little Pony/Harry Potter
Lady Magic decided that since Albus Too-Many-Middle-Names Dumbledore had plans for the newest Potter, she would send him somewhere he'd be loved and taught until he was needed on Earth. As Dumbledore left Harry James Potter on the doorstep and appearated away, Lady Magic sent the child to a different dimension where people were ponies and each had a piece of magic within them, more so than others while some could fly. To help him blend in with the other ponies, Lady Magic turned him into a baby Unicorn, a pony that could cast magic.
Bundled up in his blanket and surrounded by his basket, Baby Harry slept on without waking while Lady Magic sent him as far into the Pony Dimension as she could before letting Nature take its course. Just after Lady Magic retreated to her world a female zebra marked pony came across the basket and carried him into her home. The zebra was named Zecora and she felt the powerful magic held in this baby unicorn's body as he opened bright green eyes that focused on her own.
Before he could start to cry out, Zecora placed a bottle of milk in his mouth as she then changed his diaper quickly. "Emerald Lightning you shall be to fulfill your destiny." she muttered to the little Unicorn Colt, who fell asleep when she picked him up and sat in her small rocking chair made of bamboo.
