He vanquished a planet in the FnF manga with a blast that made both Saiyans shit their pants, which I guess is canon to Super since they skipped that whole arc entirely and only showed a glimpse of Freeza's death at Goku's hands (and the manga version was better than the movie anyways since we skipped the ray gun and Freeza killing base Gohan with one punch cancerThe better question is how did Goku/Vegeta know about it if they never saw the technique? I guess Beerus used it off screen?
