Parallel Cybermen

Parallel Cybermen are Cybermen that hail from a parallel version of Earth from a parallel universe. They were driven off the planet by the Humans there and eventually crossed the Abyss to upgrade our universe. They fought the Daleks in the Dalek-Cyberman War and were defeated, and what was left of them was pulled into the Abyss and destroyed. All that remains of these Cybermen are the Cybermen built in our universe, the Cyberman Remnant.
