Kale

Kale is a Saiyan from Universe 6 and the shy, reserved protégé of Caulifla. She harbors a rare berserker form — a Legendary Super Saiyan state comparable to Broly in raw destructive power — that she initially could not control. Under Caulifla's encouragement, Kale gradually learned to master her power and eventually achieved a controlled version of her berserk form. She fuses with Caulifla via Potara earrings during the Tournament of Power to form Kefla, one of the most powerful fighters Universe 6 has to offer.
