Dalek (Regeneration of a Dalek)
From Tardis Wiki, the free Doctor Who reference
A Dalek in a Dalek War Machine casing bearing the inscription Mk 1 on its weapons platform once regenerated by means unknown.
When the vibrant regeneration energy cleared away, it became clear that the regenerative process had completely changed around the Daleks' metallic casing as well as its physical body, and that the casing had become… a dustbin. (NOTVALID: Regeneration of a Dalek)
