Gentlemen.. BEHOLD! (This is just a basic, awful concept) This is a Shiver, named after me. It can be found on snow planets, doesn't matter where on it, though. You see it's blue hands? those are for it's attacks. They can shape into a variety of deadly weapons. It can simply punch you, or shape his hand into a spike and stab you. It can shape his hand into an axe, or melt into a puddle. When it rises from the puddle, it rises from it fast, while doing an uppercut. When it awaits you on the snow planet, it's just a puddle. When it notices you, it rises up without an uppercut, and a little bit slower. It doesn't have much of a backstory, hell, it doesn't even have one. I may update this thread a little bit soon, but for now, this is it.
Hehe, that would be funny, a player is just walking over a puddle when suddenly *pow* uppercut! Nice concept, there is some definite potential with the shape-shifting elements there.
