Kadtie also sent in a (rather adorable in my opinion)Earth champion.
"It's a golem with moss and plants growing out of it's shoulders and head. It is the champion of Earth, so it takes care of plants and animals and the ecosystem and whatnot. I see him as a gentle giant; one of my concept sketches even had a bird's nest on one of the branches on his head. Otherwise he is your basic hulk type fighter; he is no wimp. He can use pretty much any form of earth as body parts, so if you blow up one of his arms or his head or something he can just re-assimilate a new one out of the ground. On that note he is often lop-sided and uneven, sometimes with limbs made from different types of rock or soil. I picture him to be about as tall as a two story building."
