Hugo is the younger brother of Glitter Force member April Swanson. He belongs to a large family, initially one of April's five younger siblings, which grows to six children following the birth of their sister Nina. With parents often occupied, April frequently serves as Hugo's primary caregiver, reflecting their typical sibling dynamic. During a significant event, Hugo and his sister Hannah wandered unsupervised from home while April prepared dinner for their mother's imminent delivery. Searching for apples, they encountered the villain Brooha, who offered them a poisoned fruit. Merely touching the apple magically imprisoned Hugo and Hannah inside a floating, apple-shaped cage. This peril forced April to reveal her secret identity as Glitter Spring to rescue them, though Hugo remained oblivious to the magical nature of the incident. After the Glitter Force freed them, Hugo and his siblings experienced unclear memories of the event. They collectively recalled it as a shared dream where April fought a giant apple monster. When April suggested it was mere coincidence, they dismissed their recollection as imagination. This incident underscored April's strong protective instincts and the close bonds within their family.
