True to her name, Sweetie Belle is very kindhearted and innocent. Despite this, she is often mischievous, vain, naive, and impetuous.​ Being the most feminine of the three cutie mark crusaders and a true disciple of Rarity, Sweetie Belle is interested in everything concerning private relationships, displays good female qualities like adding a touch of cosiness to the CMCs' tree-house, and isn't above abusing her position as a child, manipulating adults into giving her what she wants. She, however, doesn't mind getting her hoofs dirty, even for fun, and doing some hard work, of which Rarity gives her plenty. Sweetie Belle loves her elder sister deeply, willing to go to great lengths to make her happy and becoming much upset when Rarity is ignorant to her efforts.
