Kefla is a young, slender woman of Kale’s average height. Kefla’s hairstyle is a mixture of both of those owned by the female Saiyans, being spiky like Caulifla’s with bangs framing both sides of her face while the majority of her hair is held up in a ponytail like Kale’s. Her facial features and eye shape are more reminiscent of Caulifla’s, but her complexion is a middle between both of their skin-types complexions. She wears Kale’s golden armbands however they are now the same shape as Caulifla’s wristbands, boots though the red part of them is replaced with the black of Caulifla’s, and a purple belly shirt with form-fitting purple pants (being a mixture of both of their pants) from Caulifla’s color scheme. On her ears, she has two green Potara Earrings.
In the manga, due to fusing while Kale and Caulifla were Super Saiyan, she’s stuck in a permanent Super Saiyan state and does not hold her hair up in a ponytail, which remains held up in a ponytail while Super Saiyan in the anime.
Despite being a fusion of Caulifla and Kale, Kefla’s personality is seemingly only identical to Caulifla’s, likely because Kale is shy and subservient to Caulifla in general. After being born, Kefla remarks she feels great, displaying Caulifla’s overbearing confidence. She also appears to be possessing the Universe 7 Saiyans’ desires to fight even stronger opponents and becoming stronger herself. During her initial scuffle with Goku, Kefla also displays Caulifla’s cocky attitude, calling Super Saiyan God Goku’s attacks “lame”. Her overall confidence in such abilities also has Kefla believe she can beat Goku, even if he is in his blue form.
