The Demon Collaborator

A Demon Collaborator (also known as a "Spotter" and a "Looker").

F**king demon collaborators.
~ Vergil about the Demon Collaborators (Spotters).

Spotters, also known as Demon Collaborators and Lookers, are demonically-possessed human beings that are in league with the demons and they are enemies in DmC: Devil May Cry.

They are, apparently, humans who have sided with the devils and their unholy cause. They appear to be normal until they see Dante, when they appear to cry black tears and their voices become distorted and demonic. At this point, Dante is being pulled into Limbo.
