Doppelganger is a malevolent shadow demon able to take the shape of its foe by refracting light. He acts as one of the gatekeepers of the Temen-ni-gru.
When Dante first enters the Apparition Incarnate, Dante mocks him for trying to "ask [him] some questions", saying that he's already answered them to himself. After defeating Doppelganger, Dante receives its soul as an attack Style.
- Doppelganger is similar to both the Shadow and Plasma enemies from the original Devil May Cry, he shares his shadowy composition with the Shadow and his ability to mimic his opponents with the Plasma.
- Doppelganger, along with the other gatekeepers of the Temen-ni-gru, represent one of the Seven Deadly Sins. Doppelganger represents the Sin of Pride.
- Doppelganger appear as a boss in the Devil May Cry 3 mobile game.
- In Devil May Cry 4, a dark-skinned version of Dante will appear if the player chooses Dante in Bloody Palace and fights all the way up to the last level. This version closely resembles Doppelganger.
