Key Facts

1st appearance and origin of Brainiac

1st appearance of the Bottle City of Kandor, the capital city of Krypton

[August 2025 - a recently released Superman shows storyboards of scenes that imply Brainiac is or was being considered as a villain in the DCU / September 2025 - speculation flares up again surrounding Brainiac as the villian in the Superman sequel after James Gunn posted an image of the script to social media which shows an anatomical illustration of a human head including the brain - see additional images]
