Kale and Caulifla are two imposing warriors. In the past we have talked about them emphasizing how they exalt the presence of women in the Saiyan race. They belong to Dragon Ball Universe 6, in which the planet Vegita exists and still has its population living in this world.
Different from what happens in Universe 7, where the stories of the heroes we grew up with unfold. Frieza destroyed this planet ending almost the entire race; Only Goku, Vegeta, his brother, Broly, his father, Nappa and Raditz were left alive.
So, with no women left, we couldn’t see the power they were capable of achieving. Kale and Caulifla are a sample of this.
In the two tournaments they participated in, they demonstrated their abilities, since they could even become Super Saiyans. One of them gets out of control in the same style as Broly. Then you can imagine what they are capable of achieving when they merge.
Kefla in Super Saiyan 4
Kefla is the name of the fusion of these two characters. In Dragon Ball Super they are incredibly powerful, but not capable of transforming into Super Saiyan 4. And it’s not because they can’t, but because this form is not canon in the Z sequel.
But the illustrator @XDAZE, reviewed in a note by 3D gamescompletely ignored the canonical rules and drew what the Kefla fusion would look like under this mode that goes towards the original instincts of the Super Saiyan.
