As the "girly" anchor of The Strongershine Girls, Belle radiates sweetness and purity through her signature white palette and unwavering optimism. She fiercely safeguards Landville with cheerful generosity, channeling distress into tears rather than anger when provoked. Though occasionally naive, she summons courage to support her sisters against adversity.

Her ensemble features a white skirt trimmed in black with a side bow, paired with a belly-baring black top and puffy-cupped sleeves. A black headband sporting a white rose crowns her loose ponytail, while asymmetrical gloves—diamond-studded black fingerless on her right hand, plain white on the left—accentuate her stance. Black 3-inch open-toed heels lace to mid-calf, and jewelry glimmers with a diamond-shaped snowflake necklace on a white lace choker, matched by earrings.

In combat, Belle unleashes whimsical assaults: flurries of flowers and butterflies irritate foes, while her headband morphs into a boomerang to trap targets in a giant garbage can, risking collateral damage. Her overdrive erupts as a blinding light wave, hail-laced winds, and a white energy ball that detonates into disorienting light flowers—teleporting enemies home amid cacophonous chaos.

Her sisters Bunny, Barasia, Banana, and Brennin anchor her world, alongside close allies Blossom, Bubbles, Buttercup, Bandit, Barach, Butch, Boomer, Brick, and Anna Goldman. She clashes with foes Berserk, Brute, Brat, Bully, arch-enemy Bobble, Basher, and Bouncer. Romantically, ex-boyfriends Zac Anderson and Tyler Madison precede her current relationship with Blaine.
