No, Krypton was not made of Kryptonite - at least, not initially. Kryptonite is a radioactive mineral from Krypton. The most common form is Green Kryptonite, but it comes in other forms, including Red Kryptonite, which has unusual temporary effects on Kryptonians, but only works once, and Gold Kryptonite, which would permanently remove Superman's powers. ...

Kryptonite is a transuranic element or compound (we are never told which for certain) whose inherent radioactivity inhibits the absorption of high-energy solar radiation which Kryptonians use to power their feats of superhuman ability. EFFECTS Not only does it prevent the further absorption of solar energy, it displaces, painfully, said solar energy with ...

Kryptonite blocks all of Superman's super powers including "faster than light" ability. So, once he falls under the influence of kryptonite, Superman can't escape faster than light. To use this "faster than light" ability against kryptonite, Superman needs to know about it before its radiations reaches him. As Superman doesn't have sixth sense like Spiderman,...

You're Earthling, but lots of Earth-based rocks can hurt you (Radioactive ores). Second, Kryptonite (green one) wasn't found on Krypton. It was produced during explosion of Krypton. Superman (and, Kryptonians) has superpowers on Earth because of our yellow Sun (Krypton's Sun was red). Kryptonite blocks that ability. Also, its radiation is poisonous to ...

The current explanation of the effects of Kryptonite is it drives out the energy stored in a Kryptonian's cells, weakening them greatly. It replaces the energy with Kryptonite radiation. If this happens long enough, the victim can die. The Wiki listing notes: Kryptonian characters have been shown to become immune to the effects of green kryptonite due ...

As mentioned in the comments, in most versions of Superman, he becomes immune to a piece of Red Kryptonite after a day or two of whatever change it's brought on him. Other Kryptonians tend to suffer the same effects from that piece though (which has led to characters occasionally saving a piece that has affected Superman, or Supergirl, in one particular way, ...

As far as DC canon goes, much of this is incorrect. Superman's vision and sensory powers don't "turn on" when he wants to use them (except heat vision, which is a narrowly focused blast of yellow sun radiation). His eyes work fundamentally like everyone else's. You don't choose what you see or don't see or what part of the spectrum you can or can't see, ...

In the New Earth, DCnU, there has only been three forms of kryptonite. The naturally occurring green variety and an artificially produced red and gold variants. Since the creation of New Earth, no other variants have been seen, yet. Red caused Superman's powers to become uncontrollable. Gold caused Superman to temporarily lose his powers. From the DC Wikia ...

According to the unpublished Superman story The K-Metal from Krypton, yes it is metal. The DC Wiki also claim's it's a metal. Green Kryptonite is the most common form of Kryptonite. It exists primarily as a metallic ore, but can also be found in crystalline forms. However, in the official DC canon, it probably isn't. Here are some properties of metals: ...

Derived from the Man of Steel film we can deduce or speculate upon a number of non-power traits: Atmospheric Adaptation - The film positively establishes that an adult human woman from Earth could not survive in Krypton's atmosphere. By contrast, adult Kryptonians can breath both Krypton's atmosphere and Earth's atmosphere without distress. Although a ...

This raises the interesting question of whether or not Kryponite could be liquified. But to answer this question if somehow Kryptonite was liquified and injected into Superman than he would most likely die. The danger of Krypotonite to Superman is the radiation that comes off of it. So as long as the radiation isn't changed when turned from a solid state ...

Since the debut of The New 52's "Prime-Earth", the post-Flashpoint DC Universe continuity, only Green Kryptonite has appeared. One caveat here is that The New 52 has undergone a partial-reboot in the form of 2015's Convergence. While leaving most or all of Prime-Earth's history intact, Convergence has introduced parts of some previously-rebooted DC ...

The best answer I can give you is, it depends on which Universe you refer to. Classically, kryptonite was an element formed when Krypton exploded, and that's the sole source of the mineral. So that version of the mineral would affect those Kryptonians. However! Quoting here from Wikipedia on Superboy Prime "As his reality's Krypton never exploded, there ...

Yes. This has actually happened on a number of occasions;

The Green Lantern rings are capable of creating Kryptonite and Kryptonite Radiation because the rings are capable of Energy Projection and can therefore mimic certain types of materials and energy signatures. http://dc.wikia.com/wiki/Green_Lantern_Ring Energy Projection: The ring can be used to fire blasts of Oan energy or create weapons such as ...

It would work if the Kryptonite just came to existence. However, due to it being present even before Superman could spot it, it's radiation field is already there (imagine a kryptonitishly glowing sphere around the Kryptonite) and Superman would have to penetrate some safety perimeter to get to it and thus be affected, no matter how fast he were. Of course ...

In Batman v. Superman, Kryptonite is introduced into Superman bloodstream via his respiratory system as a gas. The pathology is as follows: For the first 30 seconds, while breathing the gas, he coughs, gags, seizes up, and spasms, unable to make himself move, and clearly in pain. However, he remains conscious and can still hear Batman's taunts. Even ...

I put an answer out last month to "What actually Happens to Superman when he is exposed to Kryptonite?" question which may address this directly. You can check it out here to get some perspective: What actually happens to Superman when he is exposed to kryptonite? The simple answer? This depends on the amount of Kryptonite in proportion to sunlight ...

There are various types of kryptonite, and they all have varying effects on Superman. Each type of kryptonite contains/emits different kinds of radiation. I would think this is similar to the different radioactive elements contained within the planet Earth (plutonium, uranium, cesium, etc.) We've been told in the comic books that green kryptonite, ...

Superman's cells absorb electromagnetic radiation from yellow stars (like Earth's sun) which powers his super powers. Kryptonite's radioactivity interferes with this semi-photosynthetic process, driving the energy out of his cells in a painful fashion. So, as long as this radioactivity interference exists, his super powers would be blocked and he would be ...
