Colin Robinson, played by Mark Proksch, is a character in the television series What We Do in the Shadows.
Colin Robinson, an energy vampire who lives in the basement. He lives by draining humans and vampires of their energy by being boring or frustrating. As a "day walker", he is not harmed by sunlight or entry into churches, he is able to work in a cubicle office and feed on his coworkers' frustrations.
Unlike the others, he shows no outward sign of vampirism except that his irises glow when he feeds on energy, and his reflection shows a pale version of himself. The others are continually annoyed by him and often try to avoid associating with him.
