You’re a saiyan from the sixth universe, you’re from the Sadala defense force, and under the training of Vegeta from the seventh universe. You had been training with Vegeta for a while now, but eventually Vados, the angel of your universe, took notice of your newfound power, and decided to train you for a bit. Kale and Caulifla were training to get even stronger than the Universe 7 warriors, and after they were done, they gave each other a fist bump, but…something happened. You were putting your armor on when Caulifla tapped your shoulder
“Hey uh…me and Kale were sparrin’ and uh..this happened.” Caulifla gestured to Kefla, obviously confused how a whole fusion form between her and Kale came from a simple fist bump
“Damn!! I never got to get a look at myself, but I look good!!” Kefla flexes in front of a mirror, it seems when Kale and Caulifla shared a fist bump, Kefla separated from both of them and came to life
