CyberReaper

The CyberReaper was a mythical Cyberman.

It seemed to phase through time, reconstructing itself out of parts of damaged and dead Cybermen. The Thirteenth Doctor believed that the purpose of the CyberReaper was simply to fight the enemies of the Cybermen. However, she would later discover that its purpose was to completely nullify the enemies of the Cybermen by sowing chaos in their timelines. (GAME: The Edge of Reality)

Biography
The origins of the CyberReaper were shrouded in legend and mystery. One such legend stated that the CyberReaper was born at the end of the last Great Cyber War on the blood-drenched fields of Ryzzenbach. It was unknown how but several parts of shattered Cyber-bodies reassembled as one figure.

The CyberReaper was in charge of the Cybermen when they took control over the First's Reality Virus. His plan was to destabilise the universe to such an extent that species would not only welcome but asked for conversion. When the Thirteenth Doctor sent her companions, a human and Emer, to fight the Cybermen off, the CyberReaper would chase them. This continued when they would appear in the locations of the Death Helixes, chasing the Tenth Doctor when he got involved in the action.

It was only when they appeared in the location of the final Death Helix that the CyberReaper got to confront the Thirteenth Doctor, revealing new realities were created by the Virus including one where the Tenth Doctor stayed behind with Jeanne-Antoinette Poisson and had a family. Unable to bring herself to end this reality, the human did it for her, causing a portal to open in the sky and sucking the CyberReaper in. As a result, the universe was restored back to normal once and for all. (GAME: The Edge of Reality)
