Herobrine

Herobrine can Warp Reality to break the laws of physics allowing him to produce weapons out of thin air (materialization), walk on walls and even changing the laws of physics. Herobrine is also Omnipotent, or very nearly, and is, pretty much, invincible. Plus, he has many other unusual powers for Minecraft's entities such as being able to teleport anywhere in an instant, crafting nearly anything instantly, the capacity of destroying vast areas in seconds, electrokinesis, and so on.
