"I was under the impression that Supes becomes powerless, when in the general area of kryptonite (Writers interpretaion i guess)"
I guess it does. I always view it as he becomes powerless -after- getting exposed to it for some time.
Then again it might not be accurate anymore. I just felt the way Bats made him bleed was somewhat too easy to my taste.
"Yes characters get hurt by weaker beings, but Thor gets hurt by a lot !!!!
For example we see Deathstroke (A superstrong charcter) bouncing off Aquaman. Yet Cpatain Ammerica was able to floor King Thor !"
And yet Aquaman also lost in a h2h fight against Batman before.
Where he shouldnt considering hes also skilled and physically speaking is damn way above Bats league.
That Captain America example its kind of an exception. He didnt floored KT. The "shield" did. Wich still didnt worked. Deathstroke otoh attacked Aquaman physically speaking. He jumped at him to get him down.
Its kind of having Bats with Thors hammer. He would also hurt Superman and more. But it wouldnt be because of his own might but rather the weapon.
