Brainiac is a villainous character from DC Comics and one of the arch-enemies of Superman. A sinister alien being with a computerised mind, Brainiac is a cold, unfeeling creature that follows a single-minded directive to absorb all knowledge in the universe. To this end, he attacks inhabited planets and samples the dominant life-forms of said worlds, acquiring their scientific knowledge and collecting entire cities as specimens. He then destroys whatever remains of these planets and their cultures and will never stop until every world has been sampled and absorbed. In this sense, Brainiac's ultimate goal is to become the universe itself. He has attempted to destroy Earth on many occasions, only to be thwarted by Superman and the Justice League.
