Cyber Conversion and Upgrading

Cyber Conversion

The Cybermen prefer to completely upgrade humans into cyber form as they believe that humans would prefer this. Without emotions the Cybermen have no memories or ideas of what it is like to be truly human.

Human Emotions

The Cybermen used to be human. They began experimenting with cybernetic parts in order to survive, over time they became more cybernetic than human. During the cyber conversion they have all of their emotions removed, this is partly due to the horror of the process. Without emotions Cybermen no longer remember what it’s like to be human and they grow to believe having no emotions is a better way of life.


Cybermen had been shown to partially upgrade some humans like Toberman, but this was more mind control than replacing body parts with technology. It wasn’t until Attack of the Cybermen that we saw Cybermen completely upgrading humans. The idea was shown again in Rise of the Cybermen/The Age of Steel.
