In this particular Universe there are two kinds of humans, regular humans and those who are known as a +Anima, +Anima are shunned from all societies since regular humans don't want anything to do with the +Anima, +Anima are actually humans who have Animal powers, one thing all +Anima have is a marking somewhere on their bodies and the symbol is different depending on how the marking is shaped.
It was one fateful day when Cooro was in the woods collecting berries and other edible foods. The edible foods included certain mushrooms, fruits, wild nuts and other things to eat. That's when he sees a strange book of some sort on the ground, Cooro was never really been the type to study things, but for some reason but book seemed to pull him towards it and before he knew it he was sucked into the book.
In reality the book was a portal to another world, the world of Equestria, unlike Cooro's world humans are considered a myth there, in this world the dominant race are ponies, and they come in four types, Unicorns, only earth ponies, Pegasi and Alicorns, although there are currently three alicorns, they are Princess Celestia, Princess Luna and Princess Cadence.
The book that had sucked Cooro from his world to this world faded from existence after it had transported Cooro.
The Portal ejected Cooro just outside of the everfree forest, just outside of Sweet Apple Acres, the sun was just starting to rise. The inter-dimensional journey had drained Cooro of his energy and he needed food badly or he would collapse. That's when Cooro started smelling Apples, his favorite food in the world, he greedily climbed one of the trees and started gorging on the apples growing on it. Cooro did not know this was an apple orchard, meaning the Apples belonged to someone. After eating almost all the apples in the tree, Cooro had fallen asleep while still in the tree.
The hard working Earth pony Applejack had just gotten herself up, after she ate breakfast, she was ready to start her apple bucking for the day. That's when she notices many apple cores on the ground. She thinks to herself "Some Varmint is stealing ma apples again."
That's when she noticed Cooro sleeping in the tree that had almost all of the apples in it eaten.
Applejack "Ain't that thing a human, I thought they only a myth." She had figured out that Cooro was the one who had probably eaten all the apples so she began to buck the tree and Cooro had fallen out from the shaking of her kicks
Cooro "Owww that hurt." Applejack "Pay fer the Apple ya dang thief." Cooro "This is an orchard whoops." Applejack sighed this human boy was obviously really young probably around her little sister Apple-Bloom's age.
At that moment Cooro began to run away, Applejack "Get back here ya dang Apple Thief!" That's when Cooro activated his +Anima powers, his arms were starting to cover with black crow feathers, none on his hands though, while black crow wings were sprouting on his back. After the wings fully sprouted Cooro jumped to the air and started flapping his wings and he began to fly away like a bird.
Applejack jaw dropped, she had actually saw one of the legendary humans, but what she recalled was humans couldn't use magic and that human did not have special powers at all, however it was clear that she had seen this one sprout black
wings on his back and fly away. One of the feathers that human boy had sprouted was stuck on her Stetson. Applejack examined the feather and realized it was a Crow's feather.
After Applejack had recovered she galloped as fast as she could to Twilight's library to tell her friend what she had witnessed
Fast Forward to Twilight's house
Applejack started knocking on Twilight's door and she could hear Twilight saying "Okay, I'm coming." after Twilight opened the door she saw her good friend Applejack with a shocked expression on her face. Twilight "What's wrong Applejack are you okay?" Applejack "Sure I guess unless ya saw a human stealing ma Apples!"
Twilight started to chuckle a little "Applejack you show as well as I do humans are only myths." Applejack "That's what I thought and this one had strange powers." Twilight cocked her head a little and asked "Strange how?" Applejack "He sprouted black wings on his back and flew away that's how it was weird." Twilight "I now your the element of Honesty but do you have any proof at all AJ?" Applejack nodded her head and produced the crow feather "This was one of the wing feather's he sprouted."
Twilight used her magic to analyze the feather, and the information she had gotten worried her a little, Twilight "Applejack I think you might be right according to what I got from it even though it is a crow's feather it has no crow DNA in it at all, and I checked according to what it says, the DNA is human." Twilight "Applejack I'm gonna use a spell that will let me see today's memories okay it won't hurt at all. Applejack "I trust ya Twi."
As Twilight used her spell on Applejack she had seen everything Applejack had seen that day.The memories clearly showed Applejack was chasing a human who had stolen some of Applejack's apples, and that the human boy sprouted black bird wings on his back and flew away.
Twilight ended the spell at that point "Applejack we might need Princess Celestia for this, clearly this isn't the kind of human we have legends about, since the kind we know about have no powers, but this one clearly had crow powers."
Meanwhile with Cooro
He was still flying and thinking of that female talking pony earlier, though his experiences some +Anima could take full animal forms, but still to be able to speak, Cooro thought perhaps that Applejack was a fellow +Anima like himself.
Cooro was also not looking where he was flying and crashed into Rainbow Dash's cloud house, his head hit the door.
Rainbow Dash had been sleeping when she heard the loud knock on her door sleepily she said "I hope its not Derpy with the mail again that mare can be a menace." When Rainbow Dash opened the door, she saw Cooro still in his +Anima form, Rainbow Dash knew for sure that this being was one of those legends and myths, the human. Rainbow dash then noticed a black feather had blow into her face. Rainbow dash "Where the heck did this feather come from?" Looking down her eyes zoomed in on Cooro's black crow wings.
Rainbow Dash 'Oh that's how he got up here this guy flew here." Her eyes they bugged out as she remembered that humans are not supposed to be able to fly after remembering this she flew as fast as she could to Twillight Sparkle's house.
Once Rainbow Dash reached the library she yelled out "TWI I think I'm going Crazy!!!"
Twilight opened the door to a frantic Rainbow Dash, who the said saying "Human-b-black wings I must be going crazy!"
Applejack "Hold on sugarcube I saw him as well today he stole some of ma Apples before flying away."
