This brings up a good question. If a lantern can create anything they can imagine, is it possible to create kryptonite? and if a different lantern were to create it, would it have the effects of the different coloured kryptonite?

I don’t think it works like that. Because in the comics we don’t see them make stones with power. We mainly see solid objects and stuff like guns and beams of energy and nets or whatever for combat. I think it’s mainly just Constructs. Not like…stones with special powers. Plus the point of Kryptonite is that it’s FROM Krypton right?
