Now here's the body techniques that the 3 main deitiy groups created or used to teach others.
1. Kaio-ken( created by king Kai of the kais)
2. Ultra ego(created and used by the gods of destruction,taught to vegeta by beerus cause he can't use or achieve ultra instinct, even the gods of destruction barely or even achieved it since it's difficult or almost impossible to achieve)
3. Ultra instinct( created and used by the angels, only known user that's not an angel is goku no one taught him it and he achieved it when he was using kaio-ken in his ssjb form performing the spirit bomb and was in its blast radius and it shattered his ceiling basically a goddamn accidental fluke)
