In the Generation One continuity family, binary bonding is a process in which a Transformer enters into a symbiotic relationship with a smaller, organic being (usually an Earth human or Nebulan) who has been augmented with the ability to transform into a component or weapon. It was by this process that the Headmasters, Targetmasters and Powermasters came into being. In the three-part series finale of The Transformers, both the Autobots and Decepticons joined forces with the Nebulans. Spike and Cerebros created Fortress Maximus out of the Hive's old city, while Zarak, the Hive's evil leader, turned their new city into Scorponok.
