Getting off to a 4-0 start isn’t easy on this site, but Caulifla managed to pull it off. That’s impressive, but she couldn’t stay undefeated forever. Her power level is immense, but still not quite on the same level as Goku. His abilities are at their absolute peak and the Saiyan always seems to get stronger and stronger. His final UI form is up there as one of his strongest forms ever and may even be his absolute best. Caulifla will have to train hard if she wants to approach that kind of power. Goku wins.
