I remember being amused that Sting from the band The Police was suddenly a supporting character in during Alan Moore's now classic Swamp Thing run. Well, not really, but John Constantine was certainly illustrated to look like the famous rocker. I was surprised at how quickly the character became a fan favorite, soon getting his own series and helping to define the whole Vertigo imprint. Constantine is back to being immersed in the mainstream DCU, which is probably a turnoff to some, but I have to admit I like how he interacts with some of the more mainstream heroes.
