Kale is definitely a pretty tough fighter. She was actually taking on Super Saiyan Blue Goku after all and that’s no small feat. Still, Goku has so many different forms that he will definitely have enough energy left in the tank to defeat her. Kale’s limits just aren’t quite as high as Goku’s. Ultimately she will need more practice, but she can still make this a pretty good fight for the Saiyan. Goku wins.
