Sofia is the canon name of the female choice for the player character in Pokémon Sage. She also serves as a rival in the game if the player chooses to play as the male character. Her male counterpart is Simon.
If Sofia is selected as the player character, she starts her journey in Dacapo Town in Urobos. She is given one of the three starters of the Urobos region. Sofia goes on to gather the eight Badges of Urobos, stop the plans of Team Aurum and conquer the Pokémon League.
If Sofia is not selected as the player, she will be the player's rival and friend. She begins her own journey at the same time as the player, receiving a starter at the same time as the player does.
