think about as Super-Man vs a human can use very little energy to defeat them and send them to the moon but how is he able to use the same amount of energy when fighting some one who is equally strong as him and do the same amount of damage with same amount of force along with get hit with attacks just as strong as his own with out getting worn out or tired + since same strength why do their blows have same force of that against each other as it would against an average joe with nothing special about him
Wait, what? Are you up to those spam posts again?
I mean I'm sitting here reading your post and I'm completely puzzled whether this is a random statement or a question. And even if it is a question, then how about formulating it a bit better?
Also, do not try to drag logic into a superhero comic. They work on the "rule of cool" and disregard physics or even common sense whenever necessary.
Because superman is a terrible superhero that's basically invincible, making absolutely no point to his existence?
At least the other super heroes stick around the 1 power per superhero, while superman is stacked with ridiculously overpowered abilities. He's basically the Eric Cartman of superheroes. (ie, he has the power to have all the powers he wants, so there!)
Why watch any superman, when you know the end result: He wins and saves the day with his invincible powers.
...What?
Are you asking why Superman is sent flying/sends others flying when he's fighting fellow Kryptonians?
Part of the answer is it's more exciting to see them go flying through buildings when they get punched.
The other part is also pretty simple: There's a huge amount of force behind these punches. Just because they're equally strong doesn't mean that a punch isn't going to send them rocketing into the stratosphere. Especially when they are flying up in the air and have no way to plant themselves against an attack the same way you would if you had your feet firmly planted on the ground.
Also, Superman doesn't use the same amount of energy to punch a pursesnatcher as he does against the likes of Zod or Darkseid.
I think I'm gonna just forget that I clicked on this.
He's also a terrible superhero because all that power spoiled him. He doesn't need to know how to fight.
As to the OP, I think I might get the idea of your question. Here's an attempt to answer it:
1. As said, Superman doesn't know how to fight, because he's that overpowered. His combat techniques encompass such amazing moves like "punch harder", "move faster" and "laser eyes, pew-pew". Thus he's doing what he can best.
2. It's a comic, thus everything needs to be flashy and the supers need to show off their power.
3. Also, why should he hold himself back?
