User blog comment:Marco the Marine Admiral/Orga is not a God Slayer/@comment-1534821-20121024102351/@comment-166.111.202.30-20121024120523

Supposing that Orga is a God Slayer, I think the reason is that Orga has not yet switched to his God Slayer mode. When he is in that mode he may will use "Thunder God's XXX" as well. So I still think he is a 2nd generation.
