Goku is the kind of character who surpasses the gods in his verse with sheer training and ability. So Yato’s title won’t scare him in the slightest. Goku’s not the kind of guy to back down at all and he continues to grow stronger and stronger. Yato will have his hands full just trying to keep up with him. Once Goku goes all out then even that much will be impossible. Goku wins.
