Pyonium is an extremely powerful energy that seems to be the main source of power of the Dandy Space universe. Dandy himself seems to contain a lot of this energy, and for this reason the Gogol Empire has been trying to capture him.
Effects and Powers of Pyonium
Pyonium allows people and objects cross the space and time. It can also change the size of an object (or person), as with QT in episode 13 of the first season.
