An Ender Dalek.

An Ender Dalek is a variation of Dalek found in the Dalek mod. Unlike most mobs, it is original to the Dalek mod, spawning only in the End. The Ender Dalek is also based off the Enderman, a mob in Minecraft with the ability to teleport. It's also note worthy that there is also another variation of Daleks that is similar, known as Ender Special Weapons Daleks.
