In the current landscape of Dragon Ball continuity, Goku has become so powerful that he is able to channel god-like energy with which he is able to use to defeat even the strongest mortal foe, but he is still no match for the God of Destruction, Lord Beerus. However, there is another earthbound fighter who had one ability Goku could never attain, and with that power, could have defeated Beerus in a matter of seconds. Unfortunately, Goku accidentally killed him.

Lord Beerus made his first appearance in Dragon Ball Super Chapter 1 by Akira Toriyama and Toyotarou. In the chapter, Beerus is searching for a being that was prophesied to eventually kill him, a being known as a Super Saiyan God.

To defeat him, Beerus simply flicks Goku on the forehead with so much force, that Goku is practically incapacitated after suffering a single, effortless blow.
