Mary, the younger sister of Baraz and descendant of Ghris—a traveler who sealed Hoopa Unbound’s destructive power a century ago using the Prison Bottle—stands as a pivotal figure in the narrative. Born in Arche Valley, the settlement Ghris founded after containing Hoopa, she and Baraz grew up alongside the Mythical Pokémon in its confined form, forging an inseparable bond with it. As a child, Mary displayed a mischievous streak, frequently partnering with Hoopa to orchestrate pranks. Their antics included substituting rainfall with candy during droughts and unintentionally damaging a revered statue, actions that clashed with Baraz’s solemn adherence to their ancestral duties. Over time, she matured into a resolute guardian, mastering the powers tied to Arche Valley and assuming a protective, near-parental role over Hoopa. Her journey focuses on averting catastrophe from Hoopa’s unbound form. When Baraz retrieves the Prison Bottle and succumbs to its dark influence, Mary reclaims the artifact, forcibly reverting Hoopa to its confined state. Later, after Team Rocket shatters the bottle, she allies with Baraz to reconstruct it at Dahara Tower, channeling elemental energies to renew the seal. Their efforts inadvertently trigger spacetime distortions via summoned Legendary Pokémon, necessitating Arceus’s intervention to mend reality. Mary’s arc traces her growth from playful youth to dedicated protector, blending her inherent levity with hardened resolve. Drawing on Ghris’s legacy and her bond with Hoopa, she navigates crises with tactical ingenuity, notably during Dahara City’s chaos, where she coordinates allies to contain Hoopa’s失控 energy and repair damage from clashing Legendaries. Her relationship with Hoopa balances camaraderie and guardianship. Despite its recklessness, Mary’s unwavering commitment underscores themes of forgiveness and trust. This dynamic is further explored in the prologue short *Hoopa — The Mischief Pokémon*, which revisits their shared childhood and the trials of tempering Hoopa’s chaotic magic.
