When you think about it, doesn't it make an unfortunate kind of sense that being raised, and equally impotantly taught as a human would have an adverse effect on the development of Kal-El's special abilities? I'm borrowing this from a post I made in the Supergirl Spin-off thread, but I thought it deserved a thread of it's own.
When you really think about it, even though it has been taken way too far, and Clark seems to only discover new powers by accident or when something unusual happens to him (like sneezing or getting aroused), doesn't it make sense that an alien who looks human, was raised human, and educated as a human would be limited to a degree by human teachings?
I mean, here we have a new character, Kara Zor-El, Supergirl, entering the fray, and some people are upset about the fact that she is proclaimed to have all of Clark's powers, plus some new ones. This may seem unfair, but when you think about it, it makes perfect sense. Kara was raised and educated on a planet with an advanced alien society. She knew there was life on other worlds, and many different life-forms. She would have been taught what to expect if traveling to certain worlds, and would certainly have been taught about Kryptonian abilities when exposed to a yellow sun. Likewise, when she learned that her world was going to be destroyed, and she was charged with protecting her cousin, Kal-El, it makes perfect sense that she would learn different fighting styles to defend them both, and everything she could about the world they were going to.
Clark, on the other hand, knew nothing of his alien heritage until he was in his mid teens. He only knew he was different, and that he had to keep that fact a secret. All the while leading up to that revelation, he was taught that he was a human, and prejudiced by human teachings. Humans are flesh and bone, and havecountless limitations. There are no such things as super-heroes, or super-villains. People can't fly. If you get shot, you die. People can only run so fast, and lift so much.Earth is the only planet we have found life on. People cannot shoot lasers from their eyes, except in movies in comic books (the irony of that statement is not lost on me).
In that context, is it really any wonder that someone raised on Krypton and taught about their abilities and weaknesses would have a tremendous advantage over someone like Clark who essentially came to the USA with a manual written in Russian? He doesn't know his limits or his abilities, and he had no one to teach him, because Kara's ship was thrown off course and she was trapped in suspended animation for more than a decade.
I understand the flying argument is an old one, but just look at it from this perspective: if you've been taught your entire life that humans can't fly, and you spent most of your life believing yourself a human, would you suddenly just decide that after learning you were an alien that the laws of gravity didn't apply to you. That's no excuse after all this time in the series, but I'm just using it as an example of how a person's perceptions can shape their reality. Kara probably knows the full spectrum of her abilities on Earth, likely subconsciously taught while in suspended animation by her onboard computer. Clark had no one to teach him until the fortress became available to him, and after all the horrible experiences he has had with the Jor-El A.I., can you blame him for not completely trusting the fortress to do something awful to him during his training?
Just think how different it would have been if Kara's ship had stayed on course, and Kal-El had an older cousin to properly train him how to use his powers on Earth. He would have been Supermanby the age of thirteen. I'm just saying if you are taught to believe things are impossible, lots of times you just acceptthat as fact, even when you learn differently. How many people think that just because we haven't heard a radio signal from an alien planet, we are alone in the universe? What if they have a different means of communicating and don't use radio waves? Or what if the nearest inhabited planet is a thousand light years away, and it will be a millenium before our signals reach them, assuming they can even recognize them? What you learn when you are young shapes what you believe is possible when you are older. Clark was shortchanged by not getting a Kryptonian education.
