Elementals

After the eradication of all human life on earth, a new race of beings has taken over the earth. These new rulers being conveniently named "Elementals".

Elementals are as close to humans as you can get with one tiny difference.

Their looks, powers and weapons are all based off a specific element; either fire, water, air or earth, with each element having its own head. Heads being the most powerful, of course they get to control everyone under their own element.

However, those aren't the only elements that exist.

This story follows a small group of "freaks", elements that aren't any of the four listed. They don't have a ruler or anybody else to relate to, and there's the whole thing about all of the others wanting them dead so the earth can be perfect.

And with a new threat roaming around, this group really can't catch a break.
