The forces of nature becoming corrupt, and usual cyclic patterns going awry? Or POLLUUUUUTIONNNNN because that's a major problem.

...I claim Earth if this is a thing. I'd usually claim fire, but I've realized Earth is a nice element as well <.<;; I'll lave water to Pogs and Fire or Lightning to Natsu probably XD

Also, I had a plot similar to this maybe a decade ago, when I really, REALLY was obsessed with this stuff, and had the idea for "secondary" elements, because to be honest, air itself won't do too much.

So what if, say, Fire was a primary element, and Lightning was its secondary? (They're both plasmas, by the way.) Would be a pretty deadly combo, but the fire and lightning would have to actually /exist/ before the person could control it. Conservation of matter/energy. And the rest would be Water/Ice (mainly liquid, or something else, since Ice is just frozen water), Earth(wood, grass, anything to do with plants)/Stone (solids), and Air/Ghost (or poison, and they're all gases).
