Fan Casting Superman: Sun of Tomorrow

Superman's birthday is coming, but the celebration can't stop the crime fighting. Lex Luthor, in an attempt to end the Man of Steel's legacy, overheats him with solar radiation causing the hero to become terminally ill. With his death almost certain, he will enjoy his last week with his friends and family. Luthor, however, hasn't played his final game yet and he's certainly not going to let Clark's birthday party be a happy memory.
