As the light from the explosion that destroyed Krypton reaches Earth, the humanoid supercomputer Brainiac sets out make sure he's the only possessor of Kryptonian knowledge by destroying Superman!
This Superman Adventures volume was unexpectedly deep. When Lois cries that she's just one person but the orb contains the memories of an entire world... :'-)
Continuing on with stories of an early Superman where no one knows who he is. Here he remembers the destruction of his home planet and how he came to Earth. Brainiac escapes and demands the orb containing the Krypton memories. He attacks with cat robots that can merge and morph into giant cat robots. Lots of action and Superman fights to save the day. Not crazy about Burchett's art on this series but great story.
