Sun (Adventures)/History/Past

Sun originally lived on Cinnabar Island. One day, he was invited by his great-grandfather to come to the Alola region, only to find the man had passed away the night before he arrived. Faba, a high-ranking member of the Aether Foundation, had Sun's great-grandfather's body moved elsewhere in preparation to convert the island into Aether Paradise. When Sun protested to this, Faba jokingly suggested that Sun could buy the island back if he made 100 million yen. Sun took this statement seriously and made it his goal to get the island back and realize his great-grandfather's dream of creating the Poké Pelago.
