  On behalf of the WISE Science team, we present the discovery of a class of
distant dust-enshrouded galaxies with extremely high luminosity. These galaxies
are selected to have extreme red colors in the mid-IR using NASA's Wide-field
Infrared Survey Explorer (WISE). They are faint in the optical and near-IR,
predominantly at z=2-4, and with IR luminosity > $10^{13}\, L_{Sun}$, making
them Hyper-Luminous Infrared Galaxies (HyLIRGs). SEDs incorporating the WISE,
Spitzer, and Herschel PACS and SPIRE photometry indicate hot dust dominates the
bolometric luminosity, presumably powered by AGN. Preliminary multi-wavelength
follow-up suggests that they are different from normal populations in the local
M-sigma relation. Their low source density implies that these objects are
either intrinsically rare, or a short-lived phase in a more numerous
population. If the latter is the case, these hot, dust-enshrouded galaxies may
be an early stage in the interplay between AGN and galaxies.
