User blog comment:Marco the Marine Admiral/Orga is not a God Slayer/@comment-3271746-20121026085814

Maybe he just not into shouting out the name of his spells and stuff. I mean, only half of his spells (one, to be exact) shown in the manga is named. Moreover, when Chelia finally used one of her Sky God spells in her fight against Wendy (Chap 288), you can see that his reaction was shown (page 5). This means that they are connected, in a way. So I guess what I'm trying to say is that while it was never really confirmed that Orga is, in fact, a God Slayer, it was HEAVILY implied. Besides, we'll really know whether or not he is soon, probably in his fight against Laxus, along with explanations of why his lightning is black if he's not a God Slayer or why he doesn't use "Lightning God Slayer's" as a prefix to his spells if he is.
