1. Green kryptonite radiation weakens Superman, and can even kill him in seconds or
days depending on the amount he's exposed to, and how close it is to him.
2. Superman, like all beings, is vulnerable to magic. It can affect him in many ways and
even kill him.
3. Superman's body is like a solar battery. He'll weaken, albeit very slowly, if he's
deprived of sunlight for long periods. While this deprivation wouldn't kill him, it could
weaken him to the point where he could be killed by attacks that would never harm
him when he's at full strength. It could take days of total sunlight deprivation before
he loses all his power. In that case, re-exposure to sunlight would quickly return his
powers. Superman loses his powers when exposed to rays of a red sun.
4. Red Kryptonite has a different effect on him each time so itcould eventually kill him.
Kryptonite, a substance that was once apart of Superman's home planet, Krypton. It is green usually, and when Superman comes into close proximity with it, he is weakened. This is because the Kryptonite reacts with his own Kryptonian DNA, being apart of his own world. Basically, the Kryptonite and Superman do not react well when in close range towards each other, and this is why Superman is weakened.
