Type VI

A Type VI or K6 civilization exists in the megaverse and is capable of creating and maintaining the fundamental laws of universes. They exist in an infinite amount of simultaneously existing multiverses that represent an infinite amount of instances and all laws of physics. They can also be regarded as paraversal as they exist in infinite parallels to the 11d spacetime continuum, with infinite instances of pasts and futures. As humans become literal gods of the megaverses, they cannot be stopped unless a civilization at or beyond K7 engage in combat with humanity.
