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.
During official matches, Gloria wears a standard numbered Gym Challenger uniform. The initial one is a white striped collared shirt, which bears many logos. She also wears long white socks, as well as white shoes with red outlines, and striped shorts with logos. On her right arm, she wears a thumbless glove next to his Dynamax Band.
Gloria's appearance can be customized during the game.
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.
