"The Doom Patrol" – (24-page story) – An aging wheelchair bound scientist known only as the Chief gathers together three super-powered outcasts: Robotman, Elasti-Girl and Negative Man. As the heroes greet one another, they learn of the personal circumstances that brought them all together.

The Chief discovers a strange alien spacecraft that has crash landed on Earth. He believes that mankind's testing of atomic weapons is what attracted the aliens attention, and the unidentified ship was designed to monitor the planet's technological advancements. The Chief sends the Doom Patrol to recover a secret weapon reputedly located inside the drone ship.

Another individual learns of the ship's existence and embarks upon a plan to recover the weapon. This is the immortal mastermind, General Immortus – an old foe of the Chief's. Immortus has spy cameras set up in the Doom Patrol headquarters and is privy to many of their secrets. Immortus attempts to retrieve the weapon and encounters the Doom Patrol. During the ensuing struggle, the alien drone ship explodes and Immortus seemingly dies in the explosion.
