Just wanted to start up a thread about this semi-elusive and mysterious magic. Hiro Mashima so far has revealed 4 Dragon Slayers so far, Natsu, Gazille, Luxus (debatable due to some facts revealed), and Wendy.
Just as a quick recap of Dragon Slayer magic, according to happy who first explains it in Fairy Tail, Chapter 1 pages 70-71, Dragon Slayer Magic converts a person's body to that of a Dragon's. Therefore, one could use a Dragon's breath, be resistant to your own element and attack with said element conjured through your own magic. Continuing on Dragon Slayers are taught their magic from a dragon, and as nourishment can eat there element, as seen by Natsu and Gazille.
Judging by these rules, it seems there can be a Dragon Slayer for every element and beyond. Not only that also appears that Dragon Slayers can be created like Luxus, as shown in Chapter 128 pages 20-21.
So as a discussion, what are the possibilities that Midnight of the Oracion Six is a Dragon Slayer seeing as his magic style has been kept under raps so far. Not only that just the capabilities of Dragon Slayers seems to be infinite looking at Natsu's fight against Gerard where he takes his magic to a whole new level and Luxus who was super badass. Theoretically its possible that Dragon Slayer magic has the ability to be the most powerful magic. So what do you guys think?
