Someone downvoted me without giving a dispute, so I'm going to go ahead and support my own argument on the terms that I call out whomever dared to downvote me without giving a retort!

I think lightning would win. It can split through air. Disrupt and evaporate water. And it can quite easily charge through earth and wherever it strikes it can make fire. It is the ultimate element!

You are all stupid. It's obvious that lightning is the superior element, even if it isn't one of those listed. :p Lightning is basically just a big ass electrical current that can slice through air, become stronger when it hits water, makes fire, and can burn earth. So therefore lightning is the most kickass element ever! And to answer your question more accurately, lightning would win. :D
