This is Shade.  He is a young man, in his twenties, who came to Earth from the planet Meta.  He looks pretty human, only he can control the power of madness.  He came here to battle the American Scream, that he tracked from the Area of Madness.  He entered the body of the about to be executed serial killer Troy Grenzer.  While escaping from prison, he stumbled upon Kathy.  Both he and Kathy traveled the country following the American Scream.  On the way they met Lenny, a young and unusual woman, who decided to join them.  Shade's appearance in Kathy's life forced her to face her problems, accept the death of her parents and stop her drinking.  It also caused Shade to face demons within himself, like Hades.  Who made his life miserable, kept taking over his body, did things he could not and eventually got him killed.  Yes, Shade died, but he had lots of other problems, he was constantly looking for the new body to live in, Kathy and Lenny became lovers, and his personal life was pretty much a mess.  So, he went back to Meta and he let Stringer kill him.  After about 6 months, he is reborn into the body of a mental patient and when he comes to, he is not the old Shade.  He is more careless and thoughtless, and less poetic and idealistic.  He, Kathy, and Lenny continue to be on the road, until finally they settle in the hotel, which they call Hotel Shade.  Kathy and Lenny fall apart as lovers and Kathy and Shade get closer again.  Shade gets Kathy pregnant and they await the arrival of the child.  However, the Angels, whom Shade met during his death, and who are not like our perception of how Angels should be, wanted the child for themselves.  They wanted Shade to kill Kathy and take the child.  Shade resisted, he made a deal with the Devil, to kill the Angels.  However, the Devil was exactly what our perception of Devil is like.  So when Kathy was about to have the baby, he tricked Shade into going to the supermarket, where a man whose wife left him, shot Kathy and a few other people.  Kathy died, and her baby was used as a vehicle for the messenger of the Devil.
