This question may be more important than lunch itself. Can a Lightsaber cut through Superman. I think this might even work as an actual game, mixing the two genres, I dont remember being done before.

Anyway, heres the article.

Can a gadget defeat a superhero? Here's a question our sister site io9 posed: can a lightsaber cut through Superman? We put both our nerdy gadget knowledge and our nerdy superhero knowledge to the test and came up with reasons why it could and reasons why it couldn't.


Yes
• If the lightsaber crystal was green, like green kryptonite, or if they actually used kryptonite as the crystal, then Superman would melt like a hot knife through even hotter dog droppings.
• Superman's been injured by lasers before (see most aliens he's fought), so an extremely focused laser like a lightsaber could possibly hurt him if applied directly to the skin for a long enough time.
• If he were under the effects of kryptonite, when even bullets can hurt him, then a lightsaber could definitely chop off parts of his body.

No
• What type of radiation does the lightsaber emit? It's light, and Superman gets power from the sun, so the lightsaber could be a refreshing lamp.
• It would just burn off his clothes, like in Superman 2, but it wouldn't hurt him.
• He uses lasers (his own heat vision) to shave himself, so the best the lightsaber could do would to singe his chest hair, or give him a nice shave down there.
• Jedis can't actually cut through "everything" with the sword. Example: the big huge door in Episode I. They had to jam in their lightsabers and "melt" a doorway inside the door. The sword was fast to go into the door because they applied all the force to the tip, but was slow cutting because the Jedis are only so strong. Picture you cutting through a watermelon. In the same principle, a lightsaber technically might be able to cut through Superman, but there's nobody strong enough to force it through. Unless you somehow get the Hulk to use a lightsaber. But the Hulk doesn't exist.

Verdict: Superman wins! [Thanks to Achal for his Superman knowledge.]
