Zeus is the strongest cyber created at a Cyber Factory, and possibly one of the strongest in the game. It is available from the Nano Age, alongside the upgraded versions of the other Digital Age Cybers. Interestingly, it is in a green and blue color scheme, like the upgraded cybers it appears with, despite being the first of its model. A Zeus II does appear in the Scenario Editor, but appears nowhere in the actual game. It has an orange and red color scheme, like the Digital Age cybers.
