Type III

A Type III civilization extracts fusion and exotic energy, information, and raw-materials from their galaxy. It is capable of intergalactic travel via wormholes, intergalactic communication via subspace, galactic engineering and galaxy-scale influence. By the time humans reach this state of the scale, they can be very hard to go extinct, as the saying "Too Big to Fail" starts to apply here.

This is the final type of civilization in the original proposal of the Kardashev Scale.
