Kale

Kale is a Saiyan from Universe 6 and a member of team Universe 6. She is a member of Caulifla's gang. She is often looked down upon by the Saiyans of Universe 6, in particular Cabba, who often chews her out for being too nervous. Cabba soon instructs Kale on how to unleash her anger in order to access the Super Saiyan form. However, due to Kale's pent-up stress, she is able to utilize a "berserker" state of the form.
