Close to even God of Destruction.
For over a decade, we've been hearing that Goku has become some Saiyan God with red hair, and Beerus was forced to use about 60-70% of his power to defeat him. I'm already abstracting from the further development of these forms like Blue, Blue Evolved, or the continued enhancement of these forms by simply getting stronger in their base forms. Hell, even Ultra Instinct, which was supposed to be a game-changer and had Beerus trembling with fear– in reality, didn't change s***.
Toriyama should finally grow some balls and stop making Beerus a constant moving goalpost because the plot doesn't lead anywhere at this point. Goku needs to surpass some sensible limit for any meaningful development to occur. Instead, we keep getting these random characters from other planets like some f***ing Cheerios, Nesquik, Granolah, and despite being some random farmer with a shotgun of their planets, they can compete with "godly" forms or Ultra Instinct.
