User blog comment:Marco the Marine Admiral/Orga is not a God Slayer/@comment-5210830-20121026025939

He COULD be a God Slayer because of his lightning being black. All God Slayers elements are now black like, Zancrow's black fire and Chelia's black sky. Or we'll just wait for the next chapter in the manga to know if Orga is a God Slayer or not. :P
