Quite interesting, that. Basically the angels in Bayonetta were monstrous beneath their golden armor and milk-white, marble, human faces. In Darksiders, the Archon's skin shone with such a light that his hood was like a spotlight, but he fell to the corruption.

What I'd be asking is a little more creative liberty with either the angels normal humans cannot see or the demons contracted to some of them. Since they're not waltzing around in plain sight all the time, it makes sense to me. If anyone else feels the same way, I'm sure they'll let you know.
