Shit, even a crack rock can do it.

In fairness, Doomsday beat Superman in a straight knuckle dust up, no kryptonite required. So that's also a Superman weakness.

And in some of the stories Lex Luthor loses his hair because of his kryptonite experiments.

In Smallville, the spacecraft carrying Superman brings a kryptonite meteor swarm with it. Lex's exposure to the meteors is the cause of his premature baldness and a partial reason for his resentment of The Alien.

And in some of the stories Lex Luthor loses his hair because of his kryptonite experiments.

In the mainline comics of the ‘80s and ‘90s, wearing a kryptonite ring day after day gave him incurable cancer.

I have a short playlist of Superman songs.

• Kryptonite - 3 doors down
• Jimmy Olsen’s Blues - Spin Doctors
• Superman (Its not easy) - Five for Fighting
• Superman’s Dead - Our Lady Peace
• (Wish i could fly like) Superman - The Kinks
• Superman - REM

Always looking for more.

I means it's simple really. As the bear charges, I dodge to the side, aim for the eye and with a quick jab...get mauled and die painfully

Bro, I will use my 3 months of bbj to slip behind the bear and put him in a rear naked choke. That's right, I am going bear back.

This is the moment I wake up from a mix of blood loss and concussion from one swipe of his paw.

Also, if you throw them hard enough, all the other elements will kill you too.

It's all about the joules imparted.

A small enough rock going fast enough is just as deadly as a large one traveling slower.

Been through two medical fears already, catheter up my dick (3 times) and a broken femur. Kidney stones are still on my bucket list!

Boss brought his to work one day for show and tell.

"That came out your urethra?!"

If that was the case, Superman would have died more than once.

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.

That's just so many calories.

I think we all eat Uranium for breakfast.

What I wonder: according to lore the conditions, where supermans people live, on krypton are so harsh that they are a strong race that is like humans under those conditions.

Now sth. With the sun is there too, but lets put that aside for a moment.

So Supermans weakness is a rock of krypton. Because the rock itself must be super radioactive or sth like that.

Anything that harms superman should kill every human in the area instantly.
