Pretender Vision!

From Sunglasses After Dark:

The creatures who call themselves Pretenders dwell in the cracks in mankind’s perception. To the untutored eye they are nothing to look at: beggars, cripples, prostitutes, and anonymous strangers. Their faces are unremarkable, their demeanor bland. They normally aren’t the types who like to draw attention to themselves. Although there are numerous subcategories, they all pretend to be human, hiding their demonic otherness behind a mask of carefully constructed banality. Only to those who truly know how to see do they stand revealed, their auras suffused with fearsome energy.
