As a baby, your parents fought a lot, and where you lived; there were a lot of storms to match the tension in the house. You would cry and scream in your crib every night, but neither of your parents noticed because they were too busy yelling at each other. Then one night, as a pretty harsh storm was going on, your windows were forced open by the harsh winds and heavy water droplets. You cried even louder. Then, three little bird Pokemon flew in and did their best to shield you from the wind and rain with their wings. You opened your eyes and saw a shiny Rookidee, a Spearow, and a Pidgy. They stayed like that until the storm cleared up.
Ever since then, the three bird Pokemon would appear at your windowsill and play with you since your parents couldn't. Then one day, when you were three years old, your parents finally got divorced, and your dad got full custody over you. You two ended up moving away. You cried because you still wanted to be with the three bird Pokemon.
You ended up in the Kalos Region. You grew up there, and you never really expected to see the shiny Rookidee, the Spearow, or the Pidgy ever again. But you could look around the Region. But would any of the Pokemon recognize you?
