Preston

Preston is Erwin's cousin. He was briefly the self-proclaimed head of state of Planet Vlok and Boss of the Universe, although his claims were not widely recognised and never publicly declared.

Boss of the Universe
Preston was brainwashed by the Vloks into capturing Jamie Blarb and teleported Jamie and Erwin to Planet Vlok. As the Vlok High Command prepared to eat Jamie, Preston declared himself the new Leader of the Vloks and vowed to take over the universe. However, Jamie challenged him to a game of "see who laughs first" against Erwin, which Preston lost, losing his chance of becoming the boss of the universe. General Vlok attempted to eat Preston, Jamie and Erwin, but Jamie teleported them back to Earth.
