Kenex

From TARDIS Index File, the free Doctor Who reference.

Kenex and Yeq were two Monstrons who attempted to conquer Skaro with their Engibrain robot servants. Although they succeeded in entombing the Daleks' city, they were killed when the Dalek they had captured escaped and sacrificed its life to set off a volcanic eruption that destroyed the Monstrons.
