Justice League: A Better World
Unknown Alter Ego
Brainiac has Brainiac Spacecraft.
Brainiac is a super-intelligent alien being from the planet Colu who has fought Superman many times. Extremely advanced mental abilities that have allowed him to work through numerous robotic and even human proxies make him a dangerously formidable opponent. It is difficult to tell whether you’re dealing with the original Brainiac, or one of his drones. His obsession with knowledge has led him to shrink down many cities to bottle size for transportation on his Brainiac Spacecraft, including Kandor on Krypton. He is a frequent ally of Lex Luthor and has been a member of the Anti-Justice League.
