Assuming Superman is near the Sun, which gives him his immense power, what would happen if he was holding a small rock of Kryptonite in his hand?

Would the effects of Kryptonite cancel out due to power he gets from the sun's radiation?

  • Welcome to SFF! This question appears to answer your question by describing how Kryptonite affects Superman. Not sure if it is a duplicate or not though. – TheLethalCarrot Jun 6 '18 at 12:02
  • Thank you. I am aware that he becomes weak when exposed to Kryptonite, but I what I wish to know is that what happens if he is near the sun at the same time and draws his power from there ? Would the effect of kryptonite be negated ? – Niket Pathak Jun 6 '18 at 12:11

    The TL;DR of the accepted answer states: A sufficient amount of green Kryptonite kills Kryptonians, completely dead in under an hour. Something the size of a walnut appears to be enough. The mechanics are never explained beyond disrupting the solar energy cycle which gives Kryptonians their power and then exposing them to a toxic dose of high energy radiation. Superman Vol. 2 Number 22 shows the death of the Phantom Zone villains. Essentially it disrupts him being able to absorb solar energy so I'd say it wouldn't cancel out but I don't know. – TheLethalCarrot Jun 6 '18 at 12:16

    I would assume that being powerless near the sun would result in his immediate death – Valorum Jun 6 '18 at 14:36

    @NiketPathak - Yeah, but there wasn't any Kryptonite around to weaken him – Valorum Jun 6 '18 at 15:24

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 to either long-term absorption of sunlight (1) or extremely high short-term exposure to the sun(2).

The effects mentioned occurred in Kingdom Come(1) and All-Star Superman(2), both of which which have a nebulous place in current continuity, so the effect may not be standard, or canon.

But based on those points, increased exposure to solar radiation may help slow the effect of the Kryptonite, based on the size of the Kryptonite dose.

The effects of Kryptonite are usually temporary, with possible mental issues causing mood changes and hallucinations lasting for some time afterwards (as explained in issues of Supergirl)

EDIT / Additional - Sci.com article on effect of Green-K

Superman utilizes energy from the sun at the cellular level. Kryptonite interferes with this process, but the method by which this happens is left ambiguous. The radiation from green kryptonite might interfere with and overpower the solar radiation providing Superman with his powers. Kryptonite could simply interrupt some organic process within his body the way that a plant’s photosynthetic process could be blocked. Or, if Superman functions like a solar panel, then the radiation from kryptonite displaces electrons in Superman’s cells, preventing the movement of the electrons to create energy flow (Wilson).

  • This would appear to be somewhat correct but unsourced. Could you add the relevant evidence into your answer? – TheLethalCarrot Jun 7 '18 at 12:40
  • Additional ref added. I may try and grab Mark Waid's ear on this for a better reference, though to be honest, he's about the best reference there is when it comes to stuff like this. – VBartilucci Jun 7 '18 at 13:48

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 exposure. I would theorize that, while in the sun and being hit from afar by a Kryptonite beam, or even holding a small [possible no more than 5 inch x 5 inch] piece of green K, the radiation is going to have no significant affect; Superman's cells would be reabsorbing the pure radiation faster than the Kryptonite could drive it out.

Evidence of this is given in the 2006 Superman Returns film; Superman literally had a roughly one-inch piece of kryptonite lodged in his back from a pure Kryptonite blade Lex Luthor had stabbed him with. This was AFTER his powers were weakened by exposure to an impure Kryptonite LANDMASS the size of a large island or state. For visual reference, this is a shot of one side of said landmass against a helicopter.

Superman flew into the upper atmosphere [seen, because there was wind there], stayed in direct sunlight for no more than 30 seconds....

Super sun exposure

And was able to fly below the land mass, drill through it with his heat vision and physical punches to sever it from the earth, then fly it out into space, showing only a certain amount of strain. https://i.ytimg.com/vi/g32OeSwxPJ4/maxresdefault.jpg

Keep in mind, again that this is a land mass comprised of the one element that can weaken and kill him .... and Superman pushes it---- and the millions of gallons of water coming off of it---- into space. So he not only had enough power to shoulder the land mass....but enough to push it out of the earth's gravitational pull and toss it into space. He then fell back to earth, survived re entry, made a crater, and was unconscious for a day or so.

Oh, it should also be noted that while he was doing this feat, not only was he being exposed to still-growing Kryptonite from the island itself , seen here....

But he also had the aforementioned inch of pure Kryptonite* snapped off from the dagger still inside his back. Ere go, that Kryptonite was **still poisoning him while he was exerting himself to that level....and this was how strong he was after a.... lets be generous and say 30 second solar recharge.

This shows something pivotal: The extent to which Kryptonite can effectively counteract the solar energy in his cells is somewhat proportional to both the AMOUNT of Kryptonite, its PROXIMITY to him, and HIS proximity to the sun.

If Superman was capable of utilizing his powers to that extent while being exposed to green K externally and internally, then it should be safe to say that if he was closer to the sun directly and absorbing its radiation constantly, then the effects of the Kryptonite would be at least mitigated, if not not almost wholly dampened. This isn't to say he wouldn't experience some effects, such as pain and limited vulnerability, but if it works by "pushing the solar radiation out of his cells" and his body is being constantly inundated with fresh solar radiation, it wouldn't be in enough amount to completely poison him. Also, we have to add to this that the closer Superman is to the sun, the more solar radiation he absorbs, and being within the sun for less than half an hour allows him to draw enough strength to effortlessly move planets; in this way, if we are to assume all his abilities are heightened, so too would be his healing factor.

Now mind you, this film wouldn't be applicable as "canon" to all aspects of Superman's solar metabolism, but it does give us some parameters for answering your question in a feasible way.
