Kaniax, Almighty Death-Worlder

Kaniax is a deadly being from a Death World, a planet so deadly, it defies explanation.  However, under normal circumstances, this planet would not have turned into a Death World.  Early on in its development, a mysterious and powerful being placed a device that somehow made evolution and mutations take the most dangerous route possible, creating a world where everything is trying to kill everything.  Kaniax's species developed in this dangerous world, with a few tricks of their own.  His species are potent psychics, able to rend the very fabric of reality with some concentration, and capable of lifting mountains of rock to bring down upon their foes with but a moment's thought.  However, Kaniax was mutated to become incredibly intelligent as well, giving brains to the mental brawn his species possessed.  With his powers, he discovered the device, and vowed to find its creator and show him just what he had wrought, before taking over the universe.

Kaniax's body is weak, and it can only strike with its claws and sharp tail.  But the mental power of Kaniax is much, much more.  He can lift foes, dissolve reality, levitate, and cause explosions with his psychic powers.  He also has a long acidic tongue to pierce the armor of his foes with.

As for his creation, Kanaix is based off of many insectile aliens of yore, like the Xenomorph, and to a much greater extent, Warhammer 40,000's Tyranids.
