i agree with Tupka217. i think its Morgaine le Feys son Mordred since he did it on JLU and he is the only one who would want to do it. I mean, what adult would want to make every adult on the planet disappear. i don't think Klarion would do it since he is working with The Light and that would mean that they(the other Light members) would disappear too.
