In chapter 12 of the manga, as per the ScreenRantthe Z warriors are in a multiverse tournament and Goku is put to fight Hit, a very powerful being.
During the fight, Goku starts casually talking to the opponent and, to the surprise of the Supreme Kai from the other Universe, Hit also talks, usually not opening his mouth.
At that moment, the old Kai of the Universe of Goku says, “That’s just another of Son Goku’s mysterious qualities.”
In fact, despite having pure intentions, Goku talks to enemies and ends up making them let their guard down occasionally, as well as allowing him to know more about the opponent, making room for other strategies.
