Gloria is a short, slim young girl with fair skin, chin-length brown hair with a long strand on the left side, and brown eyes. She wears a gray hoodie over a magenta button-up dress, tartan green socks, and brown boots with lighter brown laces. She also wears black modesty shorts and dons a dark green and white tam o' shanter on top of her head. For storage, she carries around a backpack (unlike most other female protagonists in the series, Gloria doesn't use a traditional bag), though she can ditch it and use other forms of storage instead.
Apart from her basic features, Gloria's appearance in the game can be altered from the very beginning. The player is given the option to choose her starting hair color, eye color and complexion from a variety of presets. A few of these are permanent, but many of the other aspects can be customized further later on.
From what can be inferred about her mannerisms in the game, Gloria is an enthusiastic, driven girl who is a big fan of Leon. Like Selene and Elio, Gloria's dialogue options can be chosen, ranging from snarky to normal. However, unlike them, Gloria can be seen displaying varying emotions throughout the game instead of almost always having a smile on her face. (For example, she shows disgust when eating bad food that she cooks.) Her League Card can also be fitted with a multitude of poses and emotions, ranging from anger to joy to even striking a peace sign.
Gloria begins her adventure in the sleepy town of Postwick. From there, Gloria acquires a Starter Pokémon, battles Hop and the troublemaking Team Yell, conquers the Gym Challenge, defeats Leon, and stops Chairman Rose from unleashing another Darkest Day.
- Main article: Schilly
Gloria's counterpart in the Adventures manga is named "Schildemilia Tate", though she prefers to be called Schilly. Schilly is an extremely rambunctious and hyper girl who loves to talk, often having to be told to shut up by the exasperated people around her. Fittingly for her hyper personality, Schilly owns a Scorbunny.
- Pre-release media at E3 2019 referred to her as Gloria, Jane, and Shield.
