Frieza did. But not exponentially like Goku and Vegeta.
I know that zenakai boost is basically having your power exponentially increased.
But other creatures will have micro mini zenkai boost.
If I did that. It would be biased. I will give zenkai boost to everyone. But if main character can get boost of 500%. A normal character will get 10%-20%
