I would guess Ophiuchus show up possibly as an antagonist if there is a celestial spirt arc. And Draco could be a possiblity for him being dragon and possibly has knowledge of the other dragons like Igneel. I remember from the older chapters (forgot which one) Natsu said something about fighting Lucy spirits to get stronger. Draco would probably train the Dragonslayers to master Dragon Force though I could be wrong.
