The World Pokemon Champion
Sky is a proud pokemon champion from a line of pokemon trainers, it's in his blood. He's kind and easy to get along with, although he trusts nearly no one and has a strong sense of focus on his pokemon journey over anything else. His greatest passion is music, and he has taught himself how to play Lugia's song on his flute, a song that one day aids him in capturing the Beast of the Sea.
Sky has a special Pokeball known as Diamond Wing, of which the top was made of diamond, and has winged engraved into it. Coupled with this is a Diamond Flute, with which he plays Lugia's song. He used both to capture his destined legendary pokemon: Lugia. He doesn't himself battle, although he has pokemon he's captured and raised.
