Geeta holds the prestigious titles of Top Champion of the Paldea region and chairwoman of the Paldea Pokémon League, in addition to serving as the chairwoman of the school board at Naranja Academy. She is widely known across the region by the epithet "La Primera," a name that reflects her dual roles as both the region's strongest Trainer and a leading administrative figure. Known for her calm, kind, and polite demeanor, Geeta takes her considerable responsibilities very seriously. She is consistently portrayed as an encouraging and honorable person, often complimenting young Trainers on their progress and congratulating them on their achievements, such as when she praised Liko for passing a difficult test and for her heroic actions in defending the school. Despite her gentle manner, she is a formidable and experienced battler who has a genuine love for facing strong opponents, approaching battles with strategic precision and a calm, focused composure.

Geeta's primary motivation in the series is to oversee the growth of new Trainers and ensure the strength and integrity of the Paldea League. She actively supports the development of promising individuals, suggesting that Liko challenge the Paldean Pokémon League in the future and deeming her battling skills worthy of using the Terastal phenomenon. Her role in the story is largely administrative and evaluative. She and Director Clavell initially enroll the series' protagonists, Liko, Roy, and Dot, at Naranja Academy, where she explains the Tera Training course and provides them with their own Tera Orbs. Later, after being introduced to the mysterious Pokémon Terapagos, she advises the group to seek out a specialist named Raifort for more information and discusses the dangers of the Great Crater of Paldea, also known as Area Zero.

Ultimately, Geeta serves as a final gatekeeper, challenging Liko, Roy, and Dot to a battle to determine if they are prepared to enter Area Zero. She battles all three young Trainers simultaneously, a test that measures their combined strength and resolve. Despite her skill, she loses to Liko, granting the Rising Volt Tacklers the permission they sought. This battle demonstrates her role not as an unbeatable obstacle, but as a fair judge who respects the outcome of a well-fought challenge.

Geeta's key relationships are primarily professional, though she shows a noticeable interest in the protagonists. She works closely with Director Clavell in managing academy affairs and is often seen observing battles alongside the Paldea Elite Four, keeping a watchful eye on the development of Trainers like Liko. She has a particular interest in Liko's growth, personally discussing her training results and watching her battles. Her development within the series is subtle, as she begins as a distant authority figure who observes from afar and gradually becomes more directly involved, culminating in her personal battle with the young heroes. This journey shows her transition from an evaluator to an active participant in their growth.

As a battler, Geeta possesses notable abilities that live up to her rank as Top Champion. Her strategy is well-calibrated, as seen when she uses moves to increase her Pokémon's speed and disorient opponents with Dazzling Gleam to maintain control of the battlefield. Her known Pokémon include a Glimmora and two Glimmet. In her battle against Liko, Roy, and Dot, her Glimmet used the move Memento to knock themselves out after hindering the opposing Pokémon, while her Glimmora demonstrated its Toxic Debris ability, which scatters poisoned spikes when it is hit by an attack. She also utilized the Terastal phenomenon to change her Glimmora into a pure Rock-type, showcasing her mastery of the unique Paldean battle mechanic.
