Type IV

A Type IV civilization harnesses the power of its own universe. Such a civilization in fiction would be seen to a lowly type 0 civilization as an omnipotent deity. A type 4 would be effectively immortal and omnipotent. A civilization this advanced could tap into the mysterious dark matter, and which could manipulate the basic fabric of space-time. Their capabilities may include Instantaneous matter-energy transformation, teleportation, and time travel.
