So in the last edition of the Dragon Ball Super manga (I believe it was #38)
Kale was able to defeat Anilaza, which in the anime it took 2 super saiyan blue, Freezer, 17, and Gohan to defeat
I know that it's said what happens in the Dragon Ball Super manga doesnt count for the Dragon Ball Super anime, but in the other hand, we see ideas created by Toyotaro in the manga being incorporated in the anime (like the Super Saiyan God/Super Saiyan Blue switch technique and probably Vegeta turning into super saiyan god, considering the artwork we have seen released along the movie trailer, another idea made by Toyotaro)
Besides, we also saw Kale taking on a super saiyan blue kamehameha from Goku, but it looked to me that fans were in denial and argued Goku didnt use his full super saiyan blue power, when nothing could guarantee that not using his full power could also have meaning not using super saiyan blue kaioken x20, since that's Goku full power. More hints in the anime seems to point in the same direction, Vegeta saying Kale is a monster (what would he say that if she werent stronger than a super saiyan blue), Jiren taking her as a battle when he didnt bother to fight the super saiyan blue Goku and Vegeta, and so on. (Probaly more hints I dont remember right now)
Is Kale stronger than a super saiyan blue in the anime?
