Doctor Who: EVERY Version Of The Cybermen Explained

The Cybermen that originated on Hedgewick’s World were more streamlined than their predecessors, sporting sleeker, smoother suits with a retractable blaster in the right arm and a circular blue light in the chest.

They could also move at bullet speed, spin their heads 360 degrees and detach their body parts.

Most importantly of all, they could upgrade themselves on the spot to combat new threats or obstacles, making them basically unstoppable. The original batch could only be stopped by blowing up Hedgewick’s World, showing how difficult they are to beat.

Following this, these Cybermen were one of the many races that assembled around Trenzalore during the Eleventh Doctor's time there.

Missy then created an army of Weapons-Grade Cybermen from dead bodies – among those affected were Clara’s boyfriend Danny, and the Brigadier (who, along with some other Cybermen, inexplicably had black corners on his handlebars, which would designate him a Cyber-Leader).

Elsewhere, Weapons-Grade Cybermen could be found living on Trap Street and trapped in Gallifrey’s Cloisters (having tried, and failed, to enter the Matrix).

Along with its offshoots that would follow, the Weapons-Grade is by far the most technologically advanced Cyber-species we've seen to date, a perfect culmination of the Cybermen's constant desire for upgrade, survival, and universal domination.
