The Evil Twin is a demonic counterpart of the Dople added in the Halloween Update. It can be found rarely in Chapter 4 but commonly in Sheol of Chapter 5.
During Chapter 4, it has a chance to replace the Dople.
Behavior
Evil Twins have flight, and thus, cannot be killed with Spikes. However, because it has The Inner Eye, its fire speed is slowed down sharply, making shooting at angles and dodging the upgraded Dople's attacks far easier than with the normal version.
Trivia
- Evil Twins look identical to Isaac with the The Inner Eye, The Nail and the Lord Of The Pit items.
