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.
Supermans tights are red.

Fictional.
His strengths are unlimited, and I would have to admit that his only weakness is that he may be too hard of a worker, and cares about his country and its well being too much. What a jerk. his weaknes is fire!burn him!and his strength is kryptonite supermans weaknes! srry that last part was uncaled for...also another weakness is bullets...
