A peculiar instance of palaeontological past meets high-tech future. It's a robotic archaeopteryx. Ooh.
They can freely fly through cyberspace, and have access to the virtual world's code that other beasts do not.In-game description
The Cyberopteryx is the Stage 3 power-balanced form of the Wind group.
Cyberopteryxes were removed from the game before it was released, so although their data still exists, they do not appear anywhere.
A Cyberopteryx should evolve from HalkNeona, but it is disabled in the alpha version.
