Davros is the creator of the Daleks. He originally created them as just travel machines for the Kaleds, however he later secretly converted them into a war bent species known as the Daleks.
In The Mod[]
Davros was originally in the Dalek Mod, but removed due to it being found he played offensive sounds at the last minute, too late for them to be removed before the update. Khotarri stated on the forums that he would be re-added which finally happened years later in Update 60.
He is a boss mob with 200HP that can spawn in four different variants:
-1975 Davros (from Genesis & Destiny of the Daleks)
-1984 Davros (from Resurrection & Revelation of the Daleks)
-1988 Davros (from Remembrance of the Daleks)
-2008 Davros (from The Stolen Earth/Journey’s End & The Magician’s Apprentice/The Witches Familiar)
