Every time Superman was injured in the history of his comics he either:
a) didn't possess invulnerability at the time
b) didn't possess invulnerability in that era
c) had lost his invulnerability for some reason
d) was being harmed by magic
e) was weakened by kryptonite, which he did not possess an invulnerability to at the time
f) was not anywhere near the peak of his power
And to counter your absolutely ridiculous, hilarious point of Superman normally not being able to destroy a planet in the SILVER AGE, he can control his freaking power. He's not some gorilla who just smashes through everything in his path to get to his enemies. Try again...or not.
Now, go ahead and find me a few things. Do it. You have as much time as you want. Find an example of any characters from the Dragonball franchise possessing the ability to do any of the following: sneeze and destroy a distant solar system (please note that our solar system is on the smaller side), alter the fabric of existence and reality by pounding on dimensional walls, move an entire solar system of planets linked by a monstrous chain to the other side of the universe, move at thousands of times the speed of light, fly fast enough to pierce the time barrier and travel through time, fly to the edge of creation, fly fast enough to peek between dimensions and even meet God, take blasts strong enough to destroy galaxies head-on with absolutely no damage, blow out stars like candles, put out a supernova with their breath, physically defeat beings capable of absorbing entire universes, possess invulnerability to everything with the exception of magic, and have complete and absolute control over all of those powers and abilities.
At his peak, Superman can and has done all of this. Period. This is fact, to which there is no argument. If you want to contest to what did and didn't happen in the Silver Age of his comics, without even reading them, then that's your problem.
If you still want images, I have the following: Superman piercing the time barrier, Superboy prime altering reality (a being physically weaker than Superman at his max), Superman pulling a chain of planets to the other side of the universe, and to attest to his invulnerability to kryptonite at his peak, him eating it.
And realistically, the most anyone can probably do in the canon Dragonball universe is destroy a galaxy. At MOST.
