The Joining

The Joining

The Joining are the overarching antagonists of the 2004 cartoon series The Batman.

The Joining are an extraterrestrial, mental, technological, societal, militant manifestation with a determination to conquer and destroy worlds across the Galaxy, such as Earth. As Martian Manhunter (John Jones) told Batman, their first victims were their creators, a race of ancient aliens of mostly unknown origin. The Joining are reminiscent of Brainiac (an enemy of Superman), as they lust to learn everything there is to know and conquer and destroy Earth. Though their methods of attack are direct and their Units are effectively walking attack-bots and large weapons platforms, they rely on the use of replicants or duplicates to perform reconnaissance and to covertly initiate the invasion of a targeted planet.
