            Depending on the writer, there are three consistent kryptonite types:

            Green weakens him, but overall it doesn’t kill him. Strips his powers, makes him faint or just weak and nauseous.

            Blue just takes his powers away either temporarily or permanently

            Red intoxicates him or enhances his impulsiveness/brashness

            There are others, but they kind of shift of just don’t exist in the main canon

          I remember in a Lobo comic, Lobo grips a chunk of Kryptonite in his fist as he punches straight thru Superman’s chest and heart, right out the other side! Don’t fuck with the Main Man!

      Arsenic and mercury, both commonly occurring metals present in rocks, can kill humans immediately. Especially if vaporized. Uranium can kill and disable quickly in high enough concentrations.

      Also, keep in mind it’s a plot device about a fictional flying space alien with laser eyes. It doesn’t need to follow the laws of physics.

        But then they’re not rocks. It’s a vapor or a metal. That also actually disqualifies uranium as well since the rock isn’t what’s dangerous, it’s the radiation that destroys your cells. With Superman it’s literally just a rock.

      Doesn’t kryptonite just rob him of his power and severely weaken him? It’s like uranium both the time accelerated.

      it only weakens him, longer exposure can kill him. blue can negate his powers, red makes his inhibitions less. theres also gold and black(synthetic)
