Dragon Ball characters can focus their energy to a single spot to prevent planetary destruction as well as increase their destructive output. You can click the images below to make them larger.
Only in the English version of the Dragon Ball Z anime is Kid Buu’s energy attack stated to be able to destroy earth a mere ten times over. In the original manuscript (the manga/ Japanese comic) and also in the Japanese anime sub it’s never specified how much energy it is. Destroy the earth ten times is an error created by the English dub. The proof is down below.
Frieza in his first form destroyed a planet with ten times earth’s gravity and mass with JUST ONE FINGER.
That was planet Vegeta. I can prove it happened in the manga as in the Bardock Special.
The problem is 1 Kili “SUPPOSEDLY” equals 50,000 battle power/ power level.
First form Frieza’s power level is only 530,000. This means First form Frieza has only 10.6 Kili yet destroyed a giant planet easily with one finger. However, at least 200 kili are required to destroy one planet. How did Frieza do so? It must mean that SMALLER PLANETS can be destroyed with less Kili than 200 or 300 hundred kilis.
Below is an image mentioning AT LEAST 200 Kilis are needed to destroy a planet from Dragon Ball Wiki.

The company that owns Dragon Ball Z printed a guidebook in the nineties CONFIRMING CELL CAN DESTROY THE SOLAR SYSTEM. This means Cell is already SEVERAL TIMES STRONGER than what screw attack said 4th form Goku is; and 2nd form Goku is STRONGER than Cell. This guidebook is part of a lot of hard to find Dragon Ball Z information that’s officially translated in only Japanese, Chinese, or Korean. English translations are rare. I posted it at the bottom of this page.
Akira Toriyama, the inventor and original author of Dragon Ball Z, wrote a timeline around 2008 that mentioned Goku and Vegeta having a fight on a distant planet to settle who was the strongest. They created supernova explosions during the fight as a mere side effect of battling each other in Age 801.
“Goku goes missing: realizing his death is imminent and wanting to settle their rivalry, Goku leaves the Earth with Vegeta for a final battle. Years later, supernova explosions are detected; they are assumed to be from Goku and Vegeta’s battle. ”
(Goku and Vegeta are dying old men at this point, so THE AUTHOR THINKS EVEN AS DYING OLD MEN , THEY CAN GENERATE SUPERNOVAS.) According to screw attack, Superman’s infinite mass punch, which equals one supernova, is too much for 4th form Goku. BUT THE AUTHOR OF DRAGON BALL Z SAYS OLD MAN GOKU CAN GENERATE SUPERNOVAS! Come on! Isn’t it obvious who’s wrong?
All of Screw Attack’s numbers don’t match what the author said his characters can do; and the author invented those characters, not screw attack with their fan fiction.

(Super Saiyan Grade 5 was the original name of Super Saiyan 2 in Japan BEFORE Super Saiyan 3 had been invented.)
“Everything’s super!! Declare this invincible Saiya-Power!!”
“Super Saiyan Grade Five (Strongest Form). An aura with sparks like flashes of lightning and an upright, combative hairstyle are the distinguishing features of this, the strongest Saiyan warrior! One’s personality also becomes aggressive; even the ordinarily gentle Gohan started to enjoy battle! Its power is enough to push back even Cell’s energy bullet, which had enough force to blow away the Solar System!”
A Super Saiyan that has achieved a different evolution!!
Broli appeared in the movie “Burn Up!! A Red-Hot, Raging, Super Fierce Fight”. His final form resembles Super Saiyan Grade Three. But his speed is ultra first-class, and he could be called a Super Saiyan who has achieved a different evolution than Goku and the others!”
A Dragon Ball Z fan on the internet summed Screw Attack up this way.
