Kale is a Saiyan from Universe 6 and Caulifla's timid protégé in Dragon Ball Super. Despite her shy and insecure personality, she possesses the ability to transform into a Legendary Super Saiyan form similar to Broly, making her one of the most powerful Saiyans across all universes. Her berserker state grants her nearly unstoppable power but initially caused her to lose control.

Throughout the Tournament of Power, Kale's character develops as she learns to control her immense power and gains confidence through her bond with Caulifla. Together they can fuse into Kefla using the Potara earrings, combining Caulifla's skill with Kale's raw power. Her transformation from a meek, self-doubting girl into a confident warrior who can stand alongside the strongest fighters represents one of the most compelling character arcs in Dragon Ball Super. Her green-tinted Super Saiyan form and emotional depth have made her a beloved addition to the franchise.
