Brainiac (character)

Brainiac (Vril Dox) is a supervillain appearing in American comic books published by DC Comics. Created by writer Otto Binder and artist Al Plastino, Brainiac first appeared in Action Comics #242 (1958), and has since endured as one of Superman's greatest enemies. Brainiac is commonly depicted as a superintelligent android or cyborg from the planet Colu who is obsessed with collecting all knowledge in the known universe. He travels the galaxy and shrinks cities to bottle size for preservation on his skull-shaped spaceship before destroying their source planets, believing the knowledge he acquires to be most valuable if he alone possesses it.
