My theory: Natsu Gajeel Wendy Sting and Rouge (and perhaps more)? were raised by dragons so They could slay Acnologia He is à "false" dragon, all dragons fear and hate him because of what he is. But only together can They slay him. Perhaps the DS were meant to like Rouge and Sting kill Thier foster parents because They dont want to serve Acnologia
