Postcat, also known as the Mysterious Postcat, functions as an immortal operative for the mega-conglomerate CATTY & Co. within the Feline Galaxy. His core mission involves monitoring and impeding Tamala's progress, specifically to prevent her from reaching the Orion constellation. He executes this objective through direct intervention, including shooting down Tamala's personal spaceship to force a crash landing near Hate City on Planet Q.

As an enduring agent, Postcat's existence is intrinsically tied to the expansive corporate and religious agenda of CATTY & Co., which serves as a front for the ancient Minerva cult. His actions highlight the entity's pervasive influence and extensive surveillance capabilities across the galaxy.
