Type V

A Type V civilization would be advanced enough to to escape their universe of origin and explore the multiverse. Such a civilization would have mastered technology to a point where they could simulate or build a custom universe. They will have mastered the new laws of physics and have almost complete control over the fabric of reality. Now, humanity is basically impossible to destroy by its own inhabitants, which has reached the decillions.
