Zero looks like a Yellow Hunter from Nanobots, but he is colored black and blue instead of yellow, and his eyes are green. His sprite might be changed in the future.
Infinity created Zero, because, I already explained why. The purpose of organic machines would be to make them unaffected by computer viruses and EMPs. However, Zero was discarded after Infinity didn't see any use in him. Zero became vengeful, and would one day come back. He technically didn't turn evil because Infinity is even more evil. More about that when it gets a page.
- His "organic machine" concept drew inspiration from the characters of Transformers Beast Wars, as they are also organic robots. The fact that it is being used as a strategy was inspired by the Security Bot from Metroid Fusion, though in its case it was to allow it to distinguish allies from enemies.
