Professors' aides/Games/Kalos

Dexio and Sina act as Professor Sycamore's two aides and play a pivotal role in the main plot. They are first met by the player in describing the properties of the Fairy type, later appearing across Kalos at various points rallying out useful information, occasionally giving out Pokédex upgrades in the process. In the gate to Lumiose City, Dexio tells the player about friendship and gives the player, while Sina leads you to Professor Sycamore's lab after entering the main city. During activity that involves Team Flare's nefarious schemes, the twosome appear to assist the player while disguised as the self-proclaimed defenders of Kalos beginning at the Kalos Power Plant. After the player has become Champion, the duo are seen together in the parade Professor Sycamore made for the player and their friends.
