Reimagine an iconic DB attack by interpreting it's name as literally as possible. The Big Bang attack now contains the power of the actul big bang. The Kaioken summoned a chi construct of King Kai's fist. The Kamehameha now channels the power of turtles

Wolf Fang Fist Yamcha places his fist in the mouth of a wolf and then whacks his opponent with it.

Meteor Strike, Meteor Combination, Meteor Smash, Meteor Blast, Meteor Impact and Meteor Crash: gokus an earthbender now i guess

Kaioken wouldn’t necessarily be Kaio’s fist though. Kaioken is quite literally Kaio’s martial art/technique so it’s already as litteral of a naming as it can get.

Spirit Bomb wouldn’t quite be that either as the name is fairly litteral as well, it’s a sphere of energy gathered from every living thing.
