Brainiac's name is first referenced in an issue of "Hal Jordan and the Green Lantern Corps". The entirety of the Green and Yellow Lanterns (including Hal Jordan, Guy Gardner, and John Stewart), along with Starro the Conqueror, are lured into a trap and subsequently hit with a shrink ray while on the planet Xudar, leaving them tiny and helpless. In the next issue, they are trapped in a bottle, and their jailer is revealed to be a robot claiming to run on "Brainiac 2.0" software. The robot heavily resembles both Brainiac's 1983 skeleton-esque incarnation and the robotic drones utilized by the post-2008 version of Brainiac. It has a collection of shrunken bottled planets, and travels in a ship resembling Brainiac's skullship. At the time it was not clear if this was the true Brainiac after "Rebirth" or yet another one of his drones.
