About:who is koob? koobyak, also known as psillocybe koobensis or simply 'the koo', is an astral being from between dimensions inhabiting planet earth in the 21st century. as descendant of the great annunaki, a godrace from the babilonian mythology, the koo is considered to be an uberbeing. he lost his birthgiven godpowers some time ago, but other uberbeings report that he still has this unique ultraviolet glow shining from inside of him. so there is definitely some mojo left inside of koob.
