Cyborks

Cyborks're quite simply Ork cyborgs, like Imperial Servitors but with their mental faculties (such as they are) fully intact.

3rd Edition was the golden age of Orky research into this branch of the tech tree, with Cyborks available as a unit choice, Bionik Bonces, Arms, and even full Cybork Bodies readily available on the free market, and even Cyboar mounts. This period of rampant innovation was probably spurred on by Painbosses being HQ choices at the time, and thus having the authority to splurge on their pet projects to their hearts' content.

Cyborks could be taken as a bodyguard for a Painboss, in a mob of four to nine. They only had Sluggas and Choppas, with no weapons upgrades available at all, but they didn't need them, they'd been upgraded enough. For as many points as an 'Ardboy, a Cybork came with S4, T5, and a 5++ Invulnerable Save.

Cyboars meanwhile had a 4+ Armour Save and an additional CCW from all the reinforcing plates and spikes, but they tended to be even less intelligent than their unaugmented brethren, and could sometime crash into an inconvenient tree or rock and kill themselves during a charge.
