Sudan, who has traveled through the Pokémon world for seven days, holds the Digimon System in hand and stands firm with his knowledge. After witnessing Yuryudu crushing Kukui and mocking Alola for having no alliance, he decided to revitalize Alola. He exchanged the powerful Digimon Agumon and went to Kalos to recruit potential newcomers Serena and her daughter. This move angered the Kalos champion Karuna, and the two started a peak battle. Sudan will use the power of Digimon to subvert the structure of the Pokémon world and fight for the rise of Alola.
