Davros's ocular system (Unbound Universe)

The Davros of the Unbound Universe utilised an ocular system for his vision, after he was rendered blind by a Quatch attack during the Quatch Empire's first attempt at conquering the Unbound Universe's Skaro. (AUDIO: Masters of War) This ocular system was almost identical to the ocular system used by the Davros of N-Space prior to the aftermath of the Last Great Time War, (TV: Genesis of the Daleks et al.) appearing as a single artificial eye embedded within Davros' forehead, in a similar vein to the location of an eyestalk on the Daleks that the Unbound Universe's Davros created.

Several decades after receiving his ocular system, during a second attempt by the Quatch Empire to conquer Skaro, Davros' ocular system was destroyed, along with Davros himself, when the Kaled scientist activated a secret program that deactivated the technology stabilising the Quatch in the Unbound Universe, forcing them back to their native dimension; the vast instability of dozens of Quatch being forced back to their native dimension destroyed the Quatch mothership, which Davros was onboard at the time of its destruction, thereby killing him and destroying his ocular system in the process.
